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 threaded end are also known as hose nipples.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.

Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance. Use them in low-pressure applications.

Identification rings (sold separately) snap over the release ring so you can color-code your lines.

Clips (sold separately) align and organize your tubing and fittings.

A spring-free flow path allows more air or water to pass through these tube couplings at lower line pressures than other quick-disconnect couplings. This reduces turbulence, foaming, bubbles, and blockage. They have a shut-off valve that stops the flow when the coupling is disconnected, so air or water won’t leak from your line. Unlike couplings with a button release, these have a safety slide to reduce accidental separation from bumps or drops. They’re often used in laboratories, pharmaceutical facilities, and other sterile environments. All are FDA compliant for direct contact with food.

When you insert the plug into the socket, it’ll connect with a click. To disconnect, slide the latch on the socket and remove the plug.

Acetal plugs and sockets are stronger and harder than polypropylene plugs and sockets, making them less likely to scratch. Their slippery surface also makes them more wear resistant. They resist moisture, so they won't crack or become brittle when used in humid environments.

Polypropylene plugs and sockets are flexible yet tough, so they keep their shape and strength after repeated use. They are more water resistant than acetal plugs and sockets and can be completely submerged.

Note: For a complete coupling, order a plug and a socket with the same coupling size.

Instead of a gasket, these fittings have a metal-reinforced O-ring that is designed for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases. Also known as KF, QF, and NW fittings, they are the most common type of connection in high-vacuum systems. Connect with a clamp and another quick-clamp fitting for fast, easy access to your line. To use fittings in pressure applications, use a pressure-rated ring (sold separately). Made of 304 stainless steel, these fittings have very good corrosion resistance.

Note: To complete a connection, you’ll need two quick-clamp fittings, a ring, and a clamp (all sold separately).

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They withstand high pressure, so they’re often used in hydraulic applications. Made from 316 stainless steel, they resist corrosion from water and chemicals. A complete fitting requires a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
