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.

Quick-Connect High-Vacuum Fittings for Stainless Steel Tubing
Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools. To connect, insert your tubing into the fitting and twist the collar on the end of the fitting; an O-ring on the inside of the fitting compresses to form the seal. Also known as quick-disconnects, they're as easy to twist off as they are to twist on. Not for use in pressure applications.
Connectors have quick-connect fittings on both sides. Use them to connect two lengths of tubing: stainless steel to stainless steel, glass to glass, or go from one material to the other.
Adapters have a quick-connect fitting on one side and a quick-clamp fitting on the other. Use them to attach and remove components for one-off uses or to adapt your quick-clamp system to connect to glass tubing. Quick-clamp fittings are also known as KF, QF, and NW fittings; they require a clamp and ring (sold separately) to complete the connection.
