About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

Stainless steel fittings have very good corrosion resistance. 303/304 stainless steel fittings also stand up to wet and high-humidity environments.

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

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

Metal Push-On Barbed Hose Fittings for Air and Water

Fittings have sharper barbs than standard barbed hose fittings to grip rubber push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. 303/304 stainless steel fittings have very good corrosion resistance.Fittings with a threaded end are also known as hose nipples.Hose connectors are also known as hose menders and splicers. Use them to join two lengths of hose or to repair damaged hose.

The optional installation tool (sold separately) allows you to connect large quantities of barbed fittings to push-on hose. Use the built-in cutter to squarely cut the hose without fraying. Next, lubricate either the push-on hose, fitting or both. Then, clamp the hose into the tool’s vise and apply light pressure on the handle to drive into the fitting. Replace a damaged ring with a ring stop (sold separately).

NPTF (Dryseal) threads are compatible with NPT threads.

Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

Barbed Hose Fittings for Steam

Use these barbed fittings in low-pressure steam heating, humidification, and washdown applications up to 150 psi. Slide the barbed end into plastic or rubber hose and secure with a clamp. Also known as hose nipples, they adapt a barbed end to a threaded end.

303/304 stainless steel fittings have very good corrosion resistance.
