Stainless Steel Threaded Pipe and Pipe Fittings

Low-Pressure Stainless
Steel Threaded Pipe Fittings

Use these corrosion-resistant fittings in a low-pressure pipe line.

Standard-Wall Stainless Steel
Threaded Pipe Nipples and Pipe

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

Medium-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.

High-Pressure Stainless
Steel Threaded Pipe Fittings

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Stainless Steel Unthreaded Pipe and Pipe Fittings

Standard-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings

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

Standard-Wall Stainless Steel
Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure stainless steel unthreaded pipe fittings.

Extra-Thick-Wall Stainless
Steel Unthreaded Pipe

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

Thin-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings

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

Thin-Wall Stainless
Steel Unthreaded Pipe

Typically used with thin-wall stainless steel unthreaded pipe fittings.

Thick-Wall Stainless
Steel Unthreaded Pipe

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

Tube Fittings for Stainless Steel Tubing

Butt-Weld Fittings for
Stainless Steel Tubing

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

Extra-Support High-Polish Metal
Quick-Clamp Sanitary Tube Fittings

Also known as I-line fittings, the flanged end of the male adapter on these high-polish fittings interlocks with the flanged end of the female adapter to provide extra support to your line.

Extra-High-Polish Metal
Quick-Clamp Sanitary Tube Fittings

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Bolt-Together High-Vacuum
Fittings for Stainless Steel Tubing

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

High-Polish Gasket Fittings
for Stainless Steel Tubing

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

Quick-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

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.

Claw-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

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.

High-Polish Metal Quick-Clamp
Sanitary Tube Fittings

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.
