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.
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. 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.

Threaded Hose Fittings for Hydraulic Fluid
Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system.
Zinc-plated steel fittings are stronger and more durable than stainless steel fittings. They have fair corrosion resistance. Fittings that swivel until tightened rotate for easy installation.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.
BSPP threads have a gasket or a 60° internal flare to protect against leaks.
- Maximum Pressure: See table
- Temperature Range: -20° to 230° F
- Specifications Met: SAE J514
Continuous-Swivel Threaded
Hose Fittings for Hydraulic Fluid
Also known as live swivels, these fittings have ball bearings, so they can swivel continuously 360° before and after installation. This not only makes installation easier, but also eliminates the twisting and kinking that can cause premature hose failure. Fittings are threaded on both ends so you can connect them directly to a threaded hose end or to pumps, cylinders, and other equipment in your hydraulic system. They are zinc-plated steel, which has excellent strength and durability. Fittings have fair corrosion resistance.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings and meet JIC standards for dimensions.
UN/UNF (SAE) male threads have a gasket to protect against leaks. They are also known as O-ring boss threads.

Screw-On Hose Fittings for Hydraulic Fluid
These two-piece fittings screw directly onto rubber hose without the need for a separate adapter. To install, separate the two pieces of the fitting (the hose-end portion and the nipple portion). Screw the hose-end portion of the fitting onto the hose, then thread the nipple portion of the fitting into the hose-end portion. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.
Zinc-plated steel fittings offer better strength and durability than 316 stainless steel fittings. They have fair corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings. They swivel 360° until tightened for easy installation.
Notes: Fittings are only for use with hydraulic hose.

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.
