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.

Easy-Fit Barbed Hose Fittings for Air and Water

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp.

Steel fittings are stronger and more durable than other metal fittings. They should be used in noncorrosive environments. Zinc-plated steel fittings have slightly better corrosion resistance than unplated steel fittings. Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance. Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance.

Fittings with a threaded end are also known as hose nipples.

Fittings with a hex body can be tightened with a wrench.

Hose connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.

Easy-Fit Barbed Hose Fittings for Chemicals

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp. Fittings are 316 stainless steel, which has excellent corrosion resistance to withstand a variety of chemicals.

Adapters are also known as hose nipples; they adapt a barbed end to a threaded end. Adapters with a hex body can be tightened with a wrench.

Connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.
