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. Fittings with a threaded end are also known as hose nipples.
NPTF (Dryseal) threads are compatible with NPT threads.

- Maximum Pressure: 150 psi @ 72° F
- Temperature Range: -40° to 160° F
- Attachment Type: Use Crimp-On Hose Ferrules; except For 1/2" to 5/8" Hose IDs: Use Band-and-Buckle Clamps
- Specifications Met: SAE J476
Push-On Barbed Hose Fittings for Hydraulic Fluid
These fittings have sharp barbs 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. Use them in low-pressure hydraulic applications up to 350 psi. Also known as hose nipples, they adapt a barbed end to a threaded end, so you can connect to pumps, cylinders, and other equipment in your hydraulic system. Fittings are zinc-plated steel, which has excellent strength and durability. Fittings have fair corrosion resistance.
Fittings that swivel until tightened rotate 360° for easy installation.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.
