Hose Fittings

Plastic Push-On Barbed Hose Fittings for Water

Made of nylon, these fittings are lighter in weight than metal barbed hose fittings.They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

Plastic Barbed Hose Fittings
for Chemicals and Petroleum

Made of plastic, these fittings are lighter in weight than metal barbed fittings, yet have the chemical and corrosion resistance to stand up to harsh substances. Slide the barbed end into plastic or rubber hose and secure with a clamp.
