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.

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.

No need for expensive crimping tools—these fittings make air conditioning and refrigeration assemblies with clamps. Instead of a crimper, they use two clamps that you tighten against a cage on your fitting with pliers. Both fitting ends swivel until tightened, so you don't have to rotate the entire hose during installation. The cage and clamps stretch out after use, so they shouldn't be used again.
Fittings with an O-ring pilot create a leak-tight seal, so they’re often used in commercial and vehicle air conditioning systems. When you screw the fitting onto your tube, the bead and the pilot squeeze the O-ring, which fills in any gaps. The pilot also helps guide your hose onto the fitting, making it easy to properly align and secure the connection.
