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.

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.
