How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.

Front and Back Sleeves for Yor-Lok
Fittings for Stainless Steel Tubing

Couple these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on stainless steel tubing.

Nuts for Yor-Lok Fittings for Stainless Steel Tubing

PTFE Sleeves for Yor-Lok Fittings

Made of plastic, these sleeves create a strong seal without damaging tubing.
