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.

Metal Barbed Hose Fittings for Air and Water
Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance. Nickel-plated brass fittings resist corrosion better than plain brass fittings.
Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.
Stainless steel fittings have very good corrosion resistance. 303 stainless steel fittings won’t rust when exposed to water, making them good for areas that require frequent cleanings. Fittings with a threaded end are also known as hose nipples.

Metal Barbed Hose Fittings for Chemicals and Petroleum
Made of stainless steel, these fittings stand up to a wide variety of chemicals, as well as fuels, gasoline, and oils. To connect, slide the barbed end into plastic or rubber hose and secure with a clamp.
Adapters are also known as hose nipples; they adapt a barbed end to a threaded end.

Nickel-Plated Brass Low-Pressure Barbed Tube Fittings for Air and Water
The nickel plating on these brass fittings provides extra protection against corrosive environments. The plating won’t peel or chip, so the fittings keep a bright, polished appearance. The barbs grip onto tubing, providing a secure hold with no clamp required.

- Temperature Range: -40° to 230° F,
except UN/UNF (SAE Straight) Threads: -20° to 160° F - Tubing: Use with hard (Durometer 60D-90D) Buna-N rubber, EVA plastic, Nylon plastic, polyethylene plastic, polypropylene plastic, polyurethane rubber, PTFE plastic, PVC plastic, PVDF plastic, or silicone rubber,
except UN/UNF (SAE Straight) Threads: Use with firm (Durometer 85A) polyurethane rubber
