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.

- Attachment Type: Use Crimp-On Hose Ferrules, except For 1/2" Hose ID: Use Band-and-Buckle Clamps
- Specifications Met: SAE J476
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. Next, lubricate either the push-on hose, fitting or both. 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.

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.

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. 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.

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Hydraulic Fluid
Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close against each other, reducing fluid loss when connecting and disconnecting the line. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them when you need frequent access to a line. All of the International Standard ISO Minimal-Spill quick-disconnect plugs are compatible with any of the International Standard ISO Minimal-Spill quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings are compatible with ISO 16028 Parker FEM, ISO 16028 Perfecting HT, and ISO 16028 Snap-Tite 74 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated. They are zinc-plated steel, which has excellent strength and durability and fair corrosion resistance.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.

- For Use With: Air, Fuel Oil, Hydraulic Fluid, Mineral Oil
- Temperature Range: -60° to 400° F
Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°. Sleeves are zinc-plated steel for fair corrosion resistance. They are also known as ferrules.
Inch × metric sleeve adapters convert the fitting from inch to metric.

37° Flared Fittings for Aluminum Tubing
- For Use With: Air, Coolant, Gasoline, Hydraulic Fluid, Water
- Temperature Range: -60° to 400° F
- Tubing: Use with seamless aluminum
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are aluminum, which is lightweight with good corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.

Push-to-Connect Fittings for Plastic Tubing—Food and Beverage
- Temperature Range: 35° to 140° F
- Tubing: See table
- Specifications Met:
White Polypropylene: NSF/ANSI 51, NSF/ANSI 61
Black Polypropylene: FDA Compliant 21 CFR 176.170, NSF/ANSI 58, NSF/ANSI 372
Acetal: NSF/ANSI 51, NSF/ANSI 61
Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect fittings with a release ring, push on the release ring and pull the tubing out of the fitting.
Acetal fittings resist moisture, so they won’t soften and lose strength in humid environments. They meet NSF/ANSI 51 for safe use with food and NSF/ANSI 61 for safe use with drinking water.
Black fittings have excellent UV resistance and are suitable for outdoor environments.
