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.

37° Flared Fittings for Steel Tubing

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Tight-Space 37° Flared Fittings for Steel Tubing

The external hex bolt on these fittings allows for easy installation in cramped spaces.

30° Flared Fittings for Steel Tubing

Also known as JIS (Japanese Industrial Standard) fittings.

Compression Fittings for Steel Tubing

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

High-Pressure Compression Fittings for Steel Tubing

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.

Vibration-Resistant Compression
Fittings for Steel Tubing

Yor-Lok Fittings for Steel Tubing

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

Vacuum Fittings for Steel Tubing

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Clamps for Vacuum Fittings for Steel Tubing

O-Ring Face Seal Fittings for Steel Tubing

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

O-Ring Face Seal Tube Adapters for Steel Tubing

Hose Fittings

Threaded Hose Fittings for Hydraulic Fluid

Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 6,000 psi

Continuous-Swivel Threaded
Hose Fittings for Hydraulic Fluid

Also known as live swivels, these fittings swivel continuously 360° before and after installation. This not only makes installation easier, but also eliminates the twisting and kinking that can cause hose failure. Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 5,000 psi.

Push-On Barbed Hose Fittings for Hydraulic Fluid

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.

Screw-On Hose Fittings for Hydraulic Fluid

These two-piece fittings screw directly onto the hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose. Use in high-pressure hydraulic applications up to 5,800 psi.

Couplers for High-Pressure Fill Valves

Lubrication Hose Fittings

Use these two-piece fittings in grease and lubrication lines. They screw directly onto hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.
