How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Tube Sleeve Sets for Hand Bending

Protect thin-wall tubing from crimping and collapsing while bending by hand. These sets include sleeves for 6 different tube sizes.

Tube Sleeves for Hand Bending

Protect thin-wall tubing from crimping and collapsing while bending by hand.

Tube Benders for Tight Spaces

Handle-free and one quarter the size of traditional tube benders, these benders fit in small, hard-to-reach spaces.

Tube Benders

Smoothly bend hard metal tubes, such as steel and titanium, without causing crimps or kinks.

Tube Benders for Soft Metal

Tube Bending Pliers

Grip tubing from the side to make bends in tight spaces.

Tube Benders for Thick-Wall Tubing

Ratcheting action gives these tools greater leverage than standard tube benders for bending thick‐wall material.

Multisize Low-Effort Tube Bender Sets

These tools include one slide bar and 10 bending mandrels for 1/4" to 5/8" tube OD.

Multisize Low-Effort Tube Benders

Bending mandrels for 1/2" to 2" tube OD are sold separately.

Multisize Tube Benders for Soft Metal

Bend more than one size of tubing without adjusting the bending head.

Multisize Tube Benders

Make bends up to 135° in fuel, brake, and hydraulic lines.

One-Hand Multisize Tube Benders for Soft Metal

Use one hand to make bends up to 90° in soft metal tubing.

Hose Benders

Slide these hose benders over your hose and bend to form any angle up to 90°.

Tube Straighteners

Pull coiled tubing through these straighteners to make it smooth and level.

Tubing and Tube Fittings

D.O.T. Brass Compression Tube Fittings for Air

These compression tube fittings meet Department of Transportation FMVSS 571 safety standards for air brake lines.

Nuts for D.O.T. Brass Compression Tube Fittings for Air

Sleeves for D.O.T. Brass
Compression Tube Fittings for Air

Tight-Seal Brass Compression
Tube Fittings for Air and Water

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.

Low-Temperature/High-Pressure D.O.T.
Push-to-Connect Tube Fittings for Air

Use at pressures up to 250 psi.

Low-Temperature D.O.T.
Push-to-Connect Tube Fittings for Air

Use at pressures up to 150 psi.

D.O.T. Hard Plastic Tubing for Air

Also known as air brake tubing, this tubing meets D.O.T. FMVSS 106 or D.O.T. FMVSS 49 specifications for testing and performance requirements in motor vehicle brake systems.
