Tube Fittings for Metal Tubing

Precision AN 37° Flared Fittings
for Stainless Steel Tubing

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

Vibration-Resistant Precision AN 37°
Flared Fittings for Stainless Steel Tubing

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

Yor-Lok Fittings for Stainless Steel Tubing

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.

Precision Compression Fittings
for Stainless Steel Tubing

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°.

30° Flared Fittings for Steel Tubing

Also known as JIS (Japanese Industrial Standard) fittings.

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.

Yor-Lok Fittings for Copper Tubing

45° Flared Fittings for Copper and Brass Tubing

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.

Precision Compression Fittings for Copper Tubing

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

Hose and Hose Fittings

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Chemicals

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Minimal-Spill Push-and-Turn
Hose Couplings for Chemicals

Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line.

Minimal-Spill Push-and-Turn
Hose Couplings for Petroleum

Also known as dry disconnects and double shut-off couplings, these couplings make connecting and disconnecting your line quick and virtually spill-free. Built to stand up to petroleum products, such as diesel fuel and gasoline, their body and gasket are made from materials that won’t corrode from oil.

Breakaway Hose Couplings
for Chemicals and Petroleum

Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated.

Build-Your-Own High-Pressure
Braided Chemical Hose

Cut the hose to your desired length and attach the fittings. You don't need any special equipment to install.
