Typically used with low-pressure stainless steel threaded pipe fittings.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

Also known as Code 61 SAE hydraulic flanges.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

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

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Pressure Class 6000.

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

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

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

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Even in temperatures as low as -46°, these A350 LF2 steel flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications.

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

Use these unthreaded flanges in low-pressure applications. Also known as Pressure Class 125 flanges.

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

Typically used with thin-wall aluminum unthreaded pipe fittings.

Typically used with thick-wall aluminum unthreaded pipe fittings.

Also known as Pressure Class 200 pipe.

The inside of this pipe won’t leach contaminants into your line or accumulate particles—it’s polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, it resists organic solvents, acids, and alkalis better than CPVC pipe.

Also known as I-line fittings, these fittings have a male adapter that interlocks with a female adapter for more support than standard quick-clamp fittings.

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.

Use at pressures up to 4,300 psi.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

Fittings are polished to a32 Ra and under finish on the interior.

Originally used on satellites, rocket propulsion systems, and even Mars rovers, these fittings will handle your most challenging industrial environments. They're designed to withstand high vibration and high vacuum without generating particles that could disrupt your operation.
