A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Bolt these fittings onto your ultra-high-vacuum chamber to transfer liquids and gases inside. Also known as feedthroughs, they come assembled with a flanged (CF) fitting, metal tubing, and two Yor-Lok tube fittings.

Use these nuts with a sleeve and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

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

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.

The external hex bolt on these fittings allows for easy installation in cramped spaces. They are also known as banjo-style fittings and JIC (Joint Industrial Council) fittings. They provide a tight seal on tubing that is flared to 37°.

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

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.

Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required.

Crimp these fittings onto hydraulic hose for a permanent, leak-tight connection. Since they crimp on, they handle higher pressure than screw-on fittings.

Metal hose fittings have better durability than plastic barbed 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.

With an easy-to-cut hose and push-to-connect fittings, you can install a compressed air line system in just a few hours.

Bend this hose around obstructions and corners, and the aluminum tube reinforcement holds its shape.

Flare soft metal tubing.

Mount these flarers in a vise and create single and double 37° and 45° flares.

Form 45° flares in aluminum, brass, or copper tubing so it’s compatible with flared tube fittings often used in low-pressure plumbing, air conditioning, and refrigeration systems.

Create 45° flares for low-pressure applications.

Enlarge the end of a tube to allow a second piece of the same diameter to fit inside.

Stretch the end of soft plastic and rubber tubing to make room for fittings with the same or slightly larger diameter.

Create flares around already-cut holes in sheet metal up to 3/16" thick to make the edges stronger and more rigid. Also known as dimple dies.

Stop leaks from variations in temperature and vibration that can loosen 45° flared tube fittings.
