5 Pipe Wrenches Compared (2026) — Lengths, Documented Capacities and Materials

Please note: Product availability and information are based on our research at time of writing and are subject to change. Always check Amazon for the latest details before purchasing. Our assessments are research-based: we compared RIDGID’s product pages, ordering tables and warranty terms and the Amazon listings, read and captured on 12 October 2026, and we have not used these wrenches or tested their grip, strength or durability. IRWIN publishes no page for the exact model linked here, and we say so in its entry.

Introduction

A pipe wrench grips round pipe and fittings for turning: its serrated hook and heel jaws bite harder as you pull on the handle, which is why it is the tool for threaded steel and iron pipe and a poor choice for finished fittings you want to keep unmarked. The five wrenches here are all of the same type, the straight pipe wrench, and differ in three documented ways: handle length, pipe capacity and body material. RIDGID’s heavy-duty family uses a ductile-iron housing; RIDGID’s aluminum family trades that for a lighter aluminum body; the IRWIN VISE-GRIP is a cast-iron design. Capacities and weights below come from RIDGID’s ordering tables for the four RIDGID wrenches and from the Amazon listing for the IRWIN, and we say which; RIDGID’s pipe capacity and the IRWIN listing’s jaw capacity are different terms and are not compared. If you are not sure a pipe wrench is the right tool, our how to use a pipe wrench guide and our pipe wrench vs adjustable wrench comparison come first; for a wider kit, see our plumbing tool kits review, and for the under-sink tool that is not an adjustable or pipe wrench at all, our basin wrench vs adjustable wrench comparison.

We do not rank these wrenches, assign star ratings, report buyer demand or infer stock or price from a product page, and we make no claims about grip, strength, durability or how a wrench behaves on corroded fittings, which are the makers’ descriptions. The Check Price buttons keep the article’s owner-approved Amazon links so you can inspect the current seller, selected variant and offer yourself. Two of the five pages sell more than one size; each link selects one specific length, named in its entry.

Quick Comparison: Length, Capacity and Material

The table gives each wrench’s handle length, capacity measure, weight and material as its source states them, with the source under each entry. For the four RIDGID wrenches, capacity is RIDGID’s pipe capacity, “maximum nominal diameter of steel pipe”, and weight is RIDGID’s tabulated weight; the IRWIN figures are the listing’s, and its “jaw capacity” is a different term that we have not established as equivalent. The Check Price links are the article’s owner-approved Amazon links; each selects one specific length, so check the selection before you order. Offers and sellers change.

Each entry gives the documented length, capacity, weight and material with the source named, followed by the product box with the owner-approved Amazon link. None of the entries reports a test, a measured grip, a price, a stock status or a sales figure.

1. RIDGID 31015 12-inch Heavy-Duty Straight Pipe Wrench — 12 in Heavy-Duty Straight

12 in heavy-duty straight

RIDGID’s Heavy-Duty Straight Pipe Wrenches page (RIDGID product page) describes the family as having a sturdy ductile-iron housing and an I-beam handle with a full floating forged hook jaw, self-cleaning threads and replaceable hook and heel jaws. Its ordering table lists catalog 31015 as the 12 in Heavy-Duty Straight Pipe Wrench with a 12 in (300 mm) nominal size, a pipe capacity of 2 in (50 mm) and a weight of 2-3/4 lb (1.2 kg); RIDGID defines nominal size as the length of the handle and pipe capacity as the maximum nominal diameter of steel pipe. The Amazon listing identifies the 31015 in the 12 in size, repeats the ductile-iron housing and replaceable jaws, and says the 12 in wrench is ideal for pipe diameters from 1/2 in to 1-1/2 in with a capacity of up to 2 in.

The listing’s 1/2 to 1-1/2 in range is a recommended working range; the maximum is the table’s 2 in, and the two figures should not be confused. RIDGID’s Full Lifetime Warranty (warranty terms) covers defects in workmanship and material for the life of the tool, with repair or replacement at RIDGID’s option, and excludes misuse, abuse and normal wear and tear. Grip and durability are RIDGID’s descriptions, not results we measured.

2. RIDGID 31100 Model 818 18-inch Aluminum Straight Pipe Wrench — 18 in Aluminum Straight

18 in aluminum straight

RIDGID’s Aluminum Straight Pipe Wrenches page (RIDGID product page) says RIDGID Aluminum Pipe Wrenches provide professional strength in lightweight aluminum and offer the same durability and ease of use as RIDGID’s heavy-duty wrenches. Its ordering table lists catalog 31100 as Model 818, the 18 in Aluminum Straight Pipe Wrench, with an 18 in (450 mm) nominal size, a pipe capacity of 2-1/2 in (65 mm) and a weight of 3-3/4 lb (1.8 kg), against 5-1/2 lb (2.6 kg) for the 18 in heavy-duty wrench, catalog 31025, on the family page. The Amazon listing identifies the Model 818 and the 31100, repeats the aluminum material, the I-beam handle, the full floating forged hook jaw and the replaceable hook jaw, heel jaw and spring assembly, and says the 18 in wrench is ideal for pipe diameters from 1 in to 2 in with a capacity of up to 2-1/2 in.

Its weight, 3-3/4 lb, is RIDGID’s tabulated figure, against 5-1/2 lb for the 18 in heavy-duty wrench on the family page; this article quotes RIDGID’s tabulated weights. The IRWIN VISE-GRIP in entry 3 is also sold as an 18 in model, in cast iron; its 2-1/2 in is a jaw capacity from a listing, a different measure from RIDGID’s pipe capacity, so the two are not compared. Warranty terms are as in entry 1. Strength and ease of use are RIDGID’s descriptions, not results we measured.

3. IRWIN VISE-GRIP 18-inch Cast Iron Pipe Wrench, 2-1/2 in Jaw — Cast-Iron Straight

18 in cast-iron straight

IRWIN publishes no page for this exact wrench, so everything in this entry comes from its Amazon listing and none of it is confirmed by the maker. The listing is titled “IRWIN VISE-GRIP Pipe Wrench, Cast Iron, SAE, 2-1/2-Inch Jaw, 18-Inch Length (45619)”, shows model number 274103 and manufacturer part number SBD274103, states a jaw capacity of 2.5 in, and describes a cast-iron housing, per the listing, hardened teeth, a heat-treated adjusting nut, an I-beam handle and a “hammer head” flat surface. IRWIN’s current site lists cast-iron pipe wrenches in other sizes only, and we found no page for model 274103 or for “45619”.

Because there is no maker page, this wrench’s construction, its jaw capacity and its warranty are unconfirmed: the descriptions above are the seller’s, and IRWIN’s warranty for this model remains unconfirmed. The listing’s 2-1/2 in is a jaw capacity; RIDGID’s figures in the other entries are pipe capacities, defined as the maximum nominal diameter of steel pipe, and we have not established that the two measures are equivalent, so we do not compare them. The same Amazon page sells 10, 12 and 14 in versions; the article’s link selects the 18 in. The listing gives a weight, but it is not comparable to RIDGID’s tabulated weights and we do not use it.

4. RIDGID 31095 Model 814 14-inch Aluminum Straight Pipe Wrench — 14 in Aluminum Straight

14 in aluminum straight

RIDGID’s Aluminum Straight Pipe Wrenches page (RIDGID product page) lists catalog 31095 as Model 814, the 14 in Aluminum Straight Pipe Wrench, with a 14 in (350 mm) nominal size, a pipe capacity of 2 in (50 mm) and a weight of 2-1/4 lb (1.0 kg), against 3-1/2 lb (1.6 kg) for the 14 in heavy-duty wrench, catalog 31020. The Amazon listing identifies the Model 814 and the 31095, repeats the 2 in capacity, the aluminum material, the I-beam handle, the self-cleaning threads and the replaceable hook jaws, heel jaws and spring assemblies, and describes the hook jaws as full-floating forged alloy steel.

This is the middle length in the lineup. Its 2 in pipe capacity is the same as the 12 in heavy-duty 31015 in entry 1; the two differ in length and material and in RIDGID’s tabulated weights, 2-1/4 lb for this 14 in aluminum wrench and 2-3/4 lb for the 12 in 31015, so the 14 in is the lighter of the two. Warranty terms are as in entry 1. Everything about strength and ease of use is the maker’s description, not a result we measured.

5. RIDGID 31010 Model 10 10-inch Heavy-Duty Straight Pipe Wrench — 10 in Heavy-Duty Straight

10 in heavy-duty straight

RIDGID’s Heavy-Duty Straight Pipe Wrenches page (RIDGID product page) lists catalog 31010 as the 10 in Heavy-Duty Straight Pipe Wrench with a 10 in (250 mm) nominal size, a pipe capacity of 1-1/2 in (40 mm) and a weight of 1-3/4 lb (0.8 kg), in the same ductile-iron housing and I-beam handle with full floating forged hook jaw and replaceable hook and heel jaws as the rest of the family. The Amazon listing identifies it as the Model 10 / 31010, repeats the ductile-iron housing and replaceable jaws, and says the 10 in wrench is ideal for pipe diameters from 1/4 in to 1 in with a capacity of up to 1-1/2 in; its material field says alloy steel, where RIDGID’s page says ductile iron, so we use RIDGID’s wording.

It is the shortest handle in the lineup and the smallest capacity: the table’s 1-1/2 in maximum is above the listing’s 1 in recommended range, and an earlier version of this article quoted only the 1 in figure as the capacity. RIDGID also lists a 10 in aluminum wrench (catalog 31090, 1-1/4 lb, same 1-1/2 in capacity); the link here is the heavy-duty 31010. Warranty terms are as in entry 1. We have not assessed how the short handle behaves in a tight space.

Pipe Wrench Buying Guide

Wrench type: straight pipe wrenches and the others

All five wrenches here are straight pipe wrenches: a handle in line with the jaw, a hook jaw and a heel jaw that grip round pipe, and a threaded adjusting nut. RIDGID lists straight pipe wrenches as one family among several (RIDGID wrench families): end pipe, offset, chain, strap, compound-leverage and adjustable wrenches are each their own families on its site, so a wrench for a tight corner, a large pipe or a finished surface may be a different type altogether. For the choice between a pipe wrench and an adjustable wrench, our pipe wrench vs adjustable wrench comparison covers it, and for an under-sink nut our basin wrench vs adjustable wrench comparison.

Length and pipe capacity

RIDGID’s nominal size is the length of the handle, and its pipe capacity is “the maximum nominal diameter of steel pipe”. Across RIDGID’s four wrenches here: 10 in handle and 1-1/2 in pipe capacity; 12 in and 2 in; 14 in and 2 in; 18 in and 2-1/2 in. Longer handles are listed with larger capacities across RIDGID’s tables (24 in with 3 in, 36 in with 5 in), but the 12 in and 14 in wrenches share a capacity, so length alone does not tell you capacity. The IRWIN’s listing gives a “jaw capacity”, a different term from RIDGID’s, and we have not established that the two measures are equivalent. A listing’s “ideal for pipe diameters” range is narrower than the maximum capacity; the maximum is the figure to check against your pipe.

Material and weight

RIDGID’s heavy-duty wrenches have a ductile-iron housing; its aluminum wrenches replace that with aluminum and are listed lighter at the same length: 3-3/4 lb against 5-1/2 lb at 18 in, 2-1/4 lb against 3-1/2 lb at 14 in and 1-1/4 lb against 1-3/4 lb at 10 in. Across lengths, RIDGID lists the 12 in heavy-duty 31015 at 2-3/4 lb, which is more than the 14 in aluminum Model 814 at 2-1/4 lb and less than the 18 in aluminum Model 818 at 3-3/4 lb. The IRWIN is described as cast iron by its listing only. Weight here means the tabulated figure, not how a wrench feels in the hand.

Jaws, replacement parts and warranty

RIDGID’s pages describe replaceable hook and heel jaws for the heavy-duty family and replaceable hook jaw, heel jaw and spring assembly in the aluminum listings, and publish a parts list for each family. RIDGID’s Full Lifetime Warranty covers defects in workmanship and material for the life of the tool, with repair or replacement at RIDGID’s option, or a refund after three failed attempts, and does not cover misuse, abuse or normal wear and tear; hand tools are returned to the place of purchase. IRWIN’s warranty for the exact wrench linked here is unconfirmed, because IRWIN publishes no page for it, so we state no warranty for that wrench.

What a pipe wrench is not for

Serrated jaws mark what they grip. Use a pipe wrench on pipe and threaded fittings you intend to turn, not on finished chrome or soft tubing, and see our how to use a pipe wrench guide for how to set the jaws and which way to pull. Check the current seller and selected length on the Amazon page before ordering.

Frequently Asked Questions

Q: What size pipe wrench do I need for home plumbing?

Match the handle length and capacity to the largest pipe you expect to turn. RIDGID lists a pipe capacity of 1-1/2 in for the 10 in 31010, 2 in for the 12 in 31015 and the 14 in aluminum 31095, and 2-1/2 in for the 18 in aluminum 31100, defined as the maximum nominal diameter of steel pipe. The IRWIN 18 in listing gives a 2-1/2 in jaw capacity, which we have not established as equivalent. Measure or check the pipe before choosing.

Q: What is the difference between a pipe wrench and an adjustable wrench?

A pipe wrench has serrated hook and heel jaws that tighten as you pull, for gripping round pipe; an adjustable wrench has smooth parallel jaws for nuts and bolts. Our pipe wrench vs adjustable wrench comparison covers the difference in full.

Q: Why do the 12 in and 14 in wrenches have the same capacity?

RIDGID lists 2 in capacity for both the 12 in heavy-duty and the 14 in aluminum wrench in its ordering tables. The difference is handle length, material and weight: 2-3/4 lb for the 12 in 31015 and 2-1/4 lb for the 14 in Model 814, per RIDGID.

Q: Is an aluminum pipe wrench lighter than an iron one?

RIDGID’s tables list its aluminum wrenches lighter than its heavy-duty ones of the same length: 3-3/4 lb against 5-1/2 lb at 18 in and 2-1/4 lb against 3-1/2 lb at 14 in. We quote the tabulated weights; the IRWIN is described as cast iron by its listing only, and no comparable weight is available.

Q: Are prices and availability shown here?

No current price or stock status is shown. The Check Price buttons keep the article’s owner-approved Amazon links so you can inspect the current seller, selected length and offer before purchasing.

Conclusion — Which Pipe Wrench Suits Which Job?

Choose by length, pipe capacity and material. For the smallest handle here, the RIDGID 31010 is the 10 in heavy-duty wrench with a 1-1/2 in pipe capacity. For a 2 in pipe capacity RIDGID lists two lengths: the RIDGID 31015 at 12 in in a ductile-iron housing, 2-3/4 lb, and the RIDGID Model 814 at 14 in in aluminum, 2-1/4 lb. For a 2-1/2 in pipe capacity RIDGID lists the 18 in aluminum Model 818, 3-3/4 lb. The IRWIN VISE-GRIP is the 18 in cast-iron wrench whose Amazon listing gives a 2-1/2 in jaw capacity; it is documented only by that listing, and its warranty is unconfirmed. These are documented sizes and materials, not results from a hands-on test; offers, sellers and variants change, so check the page before you order.
