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.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance, so they’re the best choice for high-humidity environments.
Fittings that swivel until tightened rotate 360° for easy installation.
Fittings with a flared end meet JIC or SAE standards for dimensions. Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings. Fittings with a 45° flared end are also known as refrigeration and SAE fittings. Fittings with a female 37° and 45° flared end have a dual-angle seat that accepts both 37° and 45° flared fittings.
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. Then, clamp the hose into the tool’s vise and apply light pressure on the handle to drive into the fitting.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

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.
Fittings with a 45° flared end are also known as refrigeration and SAE fittings.

- Maximum Pressure: 250 psi @ 72° F
- Temperature Range: -40° to 160° F
- Attachment Type: Use Crimp-On Hose Ferrules, except For 1/2" Hose ID: 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.
