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. 316 stainless steel fittings have excellent corrosion resistance, so they’re the best choice for 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 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.
