About Metal Tubing

Steel

Galvanized Steel

Max. Temperature: Steel: 150° F; Galvanized Steel: 390° F
Bending Method: Tube Bender
Compatible Tube 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.

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.
