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; those with NSPM threads are also known as ball-seat fittings.
Fittings with a threaded end are also known as hose nipples.
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. 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.
NPTF (Dryseal) threads are compatible with NPT threads. NPSM (National Pipe Straight Mechanical) female threads are compatible with male NPT and NPTF threads.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

Industrial Quick-Disconnect Hose Couplings for Air
A complete coupling consists of a plug and a socket (both sold separately or in a set) that connect and disconnect quickly. Use them if you need frequent access to a line. They are also known as industrial interchange couplings. All Industrial plugs are compatible with any of the Industrial sockets of the same coupling size, regardless of the pipe size or barbed hose ID.
Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Chrome-plated steel has fair corrosion resistance and has a bright, shiny appearance. Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

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.
NPTF (Dryseal) threads are compatible with NPT threads.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

Quick-Disconnect Hose Couplings for Steam
Use these couplings for low-pressure steam heating, humidification, and washdown applications up to 300 psi. 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 quick-disconnect steam plugs are compatible with any of the quick-disconnect steam sockets of the same coupling size, regardless of the pipe size. Plugs and sockets are brass for good corrosion resistance.
Sockets have a shut-off valve that stops the flow when the coupling is separated, so steam won’t leak from the line. They swivel before and after installation as needed to prevent hose kinking. 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 back until the plug ejects.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
