Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Clamps for Claw-Clamp High-Vacuum Fittings for Stainless Steel Tubing
Connect claw-clamp high-vacuum fittings for an airtight seal. For a complete connection, you'll need four clamps and a ring (sold separately).
Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.
