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.
