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

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.

Control the flow of your line while it’s protected behind an instrument panel. These valves have threads and a hex nut below the handle, so it sticks out of your panel for access. They’re for use with water, oil, air, and inert gas.
