Vacuum-Rated Large-Diameter Steel Tubing
Steel
Galvanized Steel
- Max. Temperature: Not Rated
- Bending Method: Tube Bender
- Compatible Fittings: Vacuum
This tubing has the strength to withstand vacuum applications up to 29" Hg. It is welded and has a weld bead on the inside.
Tubing with a galvanized finish offers better corrosion resistance than unfinished steel.

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.

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.
