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.

Use these clamps to connect vacuum tube fittings. Insert two fittings into a clamp and tighten to form a secure seal.

Bolt Clamps

For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
Temperature Range: Neoprene Rubber Gaskets: -50° to 180° F
Silicone Rubber Gaskets: -100° to 500° F
Tubing: Use with steel

Bolt clamps have a stainless steel strip that provides an escape route for electrostatic buildup when used in a fully-grounded system. They have fair corrosion resistance.
