Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Typically used with extreme-pressure stainless steel unthreaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

Typically used with high-pressure iron and steel threaded pipe fittings. Also known as Schedule 160.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Typically used with high-pressure aluminum threaded pipe fittings.

Use for pressures up to 200 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

See what’s flowing through your line with this clear pipe. Since it’s Schedule 80, this pipe has thicker, stronger walls than standard-wall pipe, so you can use it for heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

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.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Use these couplings at pressures up to 10,000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO A-shape plugs and sockets.

Use these couplings at pressures up to 6,500 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Snap-Tite H-Shape plugs and sockets.

Minimize spills if a driver pulls away from your diesel exhaust fluid (DEF) pump too soon. Both halves of these couplings have a shut-off valve that stops the flow they’re separated.

Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam applications up to 600 psi. Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.

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

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

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

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.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

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.

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.
