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.

Barbed Hose Fittings for Coolant

Fittings have a barbed end that slides into rubber hose and secures with a clamp. All are nylon, which is lightweight with excellent impact and abrasion resistance. They have good corrosion resistance.

Fittings with a threaded pipe connection are also known as hose nipples. They adapt a barbed end to a threaded end.

Clamp-On Fittings for Copper Tubing

For Use With: Water
Temperature Range: 32° to 180° F
Tubing: Use with copper

Use these clamp-on fittings to make leak-resistant connections on copper tubing without threading or soldering. Slide them over tubing and turn the end nuts until hand-tight, plus a quarter turn. The gasket compresses the tubing as you tighten, creating a seal while permitting moderate movement and misalignment of tube ends. Fittings are brass for good corrosion resistance.

Copper tube size is the accepted designation of the copper tubing industry, not the actual OD.

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.

Drain Hose for Plumbing Fixtures

Drain water from washing machines and dishwashers. You’ll need a hose clamp to attach to your appliance.

Hose for washing machines has an end that can be trimmed to fit 1", 1 1/8", and 1 1/4" outlets. The hook end makes it easy to hang this hose from the lip of a sink.

Hose for dishwashers has an end that can be trimmed to fit 5/8", 3/4" and 1” outlets on your dishwasher or disposal.

Hose for washing machines and dishwashers does not come with a hose clamp to secure the hose to your appliance. Add a hook end fitting (sold separately) to hang the hose from the lip of a sink. You’ll need an additional hose clamp to attach the hook end fitting to the hose.
