About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Clamps for Vacuum Fittings for Steel Tubing

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: -20° to 190° 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.

T-Handle Clamps

For Use With: Air, Plastic Pellets
Tubing: Use with galvanized steel, steel

T-handle clamps allow you to quickly disassemble and reassemble your line without tools. They offer very good corrosion resistance.

Vacuum Fittings for Steel Tubing

For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
Temperature Range: -10° to 180° F
Tubing: Galvanized Steel: Use with steel, galvanized steel
Steel: Use with steel

Use these fittings to create an air vacuum system without the hassle of brazing and welding. Insert two fittings into a clamp (sold separately) and tighten to form a secure seal.

Galvanized steel fittings have fair corrosion resistance. Fittings without a finish should only be used in noncorrosive environments.
