Bahco 9073 RP US

Best Overall
Jaw Capacity1-3/8 in (35mm)
Overall Length12 in
HandleThermoplastic (Ergo)
FinishBlack phosphate
Pros
  • Reversible jaw doubles as an adjustable wrench
  • Aggressive angled teeth grip firmly
  • Slim tapered jaws fit tight spaces
Cons
  • Higher price than the smaller 9071
  • Smaller jaw capacity than heavy Stillson-type wrenches

The Bahco 9073 RP US is part of Bahco's ERGO combination line, pairing a reversible jaw with aggressive angled teeth that bite into pipes and fittings without slipping. The reversible jaw also lets it double as an adjustable wrench, so one tool covers two jobs on a service call. Owner reviews consistently praise the secure grip and the slim, tapered head that reaches into confined areas.

At 12 inches overall with a 1-3/8 in jaw capacity, it covers most residential and light commercial plumbing tasks. The black phosphate finish resists corrosion better than bare steel. While it costs more than the smaller 9071 RP US, the added reach and reversible-jaw versatility justify the investment for regular use.

Expert take: The 9073 RP US is the go-to for professionals who need a reliable, non-slip grip plus adjustable-wrench versatility. Its slim head is a real advantage in confined spaces.

Bahco 9071 RP US

Best Budget
Jaw Capacity1-1/16 in (27mm)
Overall Length8 in
HandleThermoplastic (Ergo)
FinishBlack phosphate
Pros
  • Affordable price point
  • Good grip for smaller fittings
  • Compact, lightweight design
Cons
  • Smaller jaw capacity than the 9073
  • 8-inch length limits leverage

The Bahco 9071 RP US offers a solid entry point into the ERGO combination line without the premium cost of the 9073. At 8 inches overall with a 1-1/16 in jaw capacity, it handles smaller fittings and lighter plumbing tasks well. Owner reviews note it performs well for home use and occasional professional work.

Like the rest of the ERGO line, it uses a reversible jaw and thermoplastic handle, and the black phosphate finish holds up well with basic care. The shorter length means less leverage than the 12-inch 9073, but for the price it is a dependable tool that many users find adequate for their needs.

Expert take: A smart choice for DIYers who want Bahco ERGO quality without the higher cost of the 12-inch model. It is a capable wrench for most residential plumbing jobs.

Bahco 361-36

Best Heavy-Duty
Jaw Capacity4 in (102mm)
Overall Length36 in
Weight~13.4 lbs (6.1 kg)
ConstructionChrome vanadium, hardened jaws
Pros
  • Large 4-in jaw capacity
  • Excellent leverage for large pipes
  • Chrome vanadium, corrosion-treated construction
Cons
  • Heavy and bulky
  • Overkill for small jobs

The Bahco 361-36 is a traditional Stillson-type pipe wrench built for industrial and heavy commercial applications. Its 4-inch jaw capacity handles large-diameter pipe, making it suitable for large-scale plumbing, irrigation, or gas line work. The 36-inch handle provides substantial leverage for breaking loose stubborn, large-diameter fittings.

At roughly 13.4 lbs, this wrench is not for everyday household tasks. It is a specialized tool for specific, demanding jobs. The deep-grooved, induction-hardened jaws grip and turn large pipes without slipping, even under high torque, and the chrome vanadium body is treated to resist corrosion in harsh environments.

Expert take: The 361-36 is the right choice for professionals who regularly work with large-diameter pipes. Its build quality and grip are unmatched for heavy-duty use.

Bahco 361-8

Best Compact
Jaw Capacity1 in (25mm)
Overall Length8 in
TypeStillson
ConstructionForged steel, corrosion-treated
Pros
  • Excellent for tight spaces
  • Lightweight and portable
  • Good grip for its size
Cons
  • Limited leverage
  • Smaller jaw capacity

The Bahco 361-8 is designed for working in confined areas like under sinks or inside cabinets. Its short, 8-inch body allows it to fit where larger wrenches cannot. As a classic Stillson-type wrench, it uses deep-grooved jaws for a secure grip on smaller pipes and fittings.

This wrench is ideal for precision work and quick adjustments in tight spots. Its 1-inch jaw capacity and shorter body mean less leverage than the 361-36, so it is not suited to breaking loose very tight, large fittings. Owner reviews appreciate its build quality and how it handles in cramped conditions, making it a valuable addition to a plumber's toolkit.

Expert take: A must-have for any plumber who works in tight spaces. The 361-8 offers the same Stillson-type grip as the larger Bahco wrenches in a compact, maneuverable package.

Bahco 9072 RP US

Best Ergonomics
Jaw Capacity1-5/16 in (33mm)
Overall Length10 in
HandleThermoplastic (Ergo)
FinishBlack phosphate
Pros
  • Comfortable Ergo thermoplastic handle
  • Reversible jaw adds versatility
  • Good mid-size balance of reach and control
Cons
  • Not as heavy-duty as Stillson-type wrenches
  • Premium price for a combination tool

The Bahco 9072 RP US sits in the middle of the ERGO combination line, focusing on user comfort with a thermoplastic Ergo handle that reduces hand fatigue during extended use. At 10 inches with a 1-5/16 in jaw capacity, it splits the difference between the compact 9071 and the larger 9073. The reversible jaw still bites securely into pipes and fittings.

Like the rest of the ERGO line, it is not built for the heaviest industrial jobs the way a Stillson-type wrench like the 361-36 is, and the combination design carries a premium over a basic pipe wrench of the same size. For users who prioritize comfort and a two-in-one adjustable/pipe wrench, the 9072 is a strong contender.

Expert take: The 9072 RP US is a great choice for plumbers who work long hours and want a comfortable grip without stepping down to the smallest 9071. Its reversible jaw adds real everyday versatility.

What to check before buying a Bahco pipe wrench

Choosing the right pipe wrench involves more than just picking a brand. Consider the typical pipe sizes you work with. A 10 or 12-inch ERGO combination wrench like the 9072 or 9073 is a versatile starting point for most residential jobs. For larger commercial work, a longer Stillson-type wrench like the 361-36 provides the necessary leverage and jaw capacity.

Think about the working environment. If you often work in tight spaces like under sinks, a compact 8-inch model such as the 361-8 or 9071 is essential. For heavy-duty jobs on large pipes, a Stillson-type wrench like the 361-36 is necessary. The finish is also important; a phosphate or corrosion-treated finish holds up better than bare steel in damp conditions.

Mistakes to avoid when using a pipe wrench

A common mistake is using a pipe wrench on nuts or bolts. The aggressive jaw teeth can damage the corners of fasteners. Always use a proper wrench or socket for nuts and bolts. Pipe wrenches are designed for gripping and turning pipes and rounded objects.

Another error is applying force in the wrong direction. Pipe wrenches are designed to grip when turned in one direction. Ensure the jaw is oriented to bite into the pipe when you apply force. Pushing in the wrong direction can cause the wrench to slip, potentially damaging the pipe or causing injury.

FAQs

Are Bahco pipe wrenches made in Sweden?

Bahco was founded in Sweden and its hand tools are engineered under Swedish design standards, but manufacturing for SNA Europe (Bahco's parent company) is spread across multiple facilities, so the country of origin can vary by product line.

What is the difference between the Bahco 9073 and 9071?

The 9073 RP US has a larger 1-3/8 in jaw capacity and a 12-inch overall length for bigger pipes and better leverage. The 9071 RP US is an 8-inch model with a 1-1/16 in jaw capacity, sized for smaller fittings and a lower price.

Can I use a Bahco pipe wrench on chrome pipes?

It is not recommended as the aggressive teeth can scratch and damage the chrome finish. Use a strap wrench or a pipe wrench with a softer jaw insert for chrome pipes.

What size Bahco pipe wrench should I buy first?

A 10-inch ERGO combination wrench like the 9072 RP US is a good starting point for most homeowners and DIYers. It offers a solid balance of reach and jaw capacity for typical residential plumbing tasks.

Do Bahco pipe wrenches have a warranty?

Yes, Bahco tools typically come with a limited lifetime warranty against defects in materials and workmanship. Check the specific product documentation for details.

How do I adjust a Bahco pipe wrench?

Turn the knurled adjusting nut located at the base of the movable jaw. Turn it clockwise to tighten the jaw opening and counter-clockwise to loosen it.

Are Bahco wrenches better than Ridgid?

Both are top-tier brands. Bahco is often favored for its lighter weight and aggressive grip, while Ridgid is known for its robust, heavy-duty construction and replaceable jaws. The best choice depends on personal preference and specific needs.

Can I use a pipe wrench on gas lines?

Yes, a pipe wrench is commonly used on black iron gas pipes. Ensure the wrench is properly adjusted and the jaw is biting securely to avoid sparks or damage.

How do I clean and maintain my Bahco pipe wrench?

Wipe it clean after use to remove dirt and moisture. Occasionally apply a light coat of oil to the adjusting nut and hinge to keep it moving smoothly. Store it in a dry place to prevent rust.

What does the number on a Bahco wrench mean?

The number identifies the product series, and a suffix like RP US or RPC US indicates finish (black phosphate or chrome) on the ERGO combination wrenches. For example, 9071, 9072, and 9073 are the 8, 10, and 12-inch models in that line.

Our verdict

For most users, the Bahco 9073 RP US is the best overall pipe wrench, offering a strong combination of reversible-jaw grip, durability, and reach. If you are on a tighter budget, the Bahco 9071 RP US provides reliable performance at a lower cost, making it the best budget pick for DIYers.
