Made of polypropylene, these fittings have good corrosion and abrasion resistance, and are lighter in weight than metal barbed hose fittings. Slide the barbed end into plastic or rubber hose and secure with a clamp.

Fittings with a threaded end are also known as hose nipples.

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. Fittings with a threaded end are also known as hose nipples.

Hose connectors are also known as hose menders and splicers. Use them to join two lengths of hose or to repair damaged hose.

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. Replace a damaged ring with a ring stop (sold separately).

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.

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into rubber hose and secure with a clamp or a crimp-on hose ferrule. The nut swivels until tightened for easy installation. Fittings are brass for good corrosion resistance.

NPSM (National Pipe Straight Mechanical) female threads are compatible with male NPT and NPTF (Dryseal) threads.

A complete coupling consists of a plug and a socket (both sold separately) 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.

Plugs are also known as nipples. Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.

Plugs and sockets with a clamp-on/crimp-on barbed end insert into rubber hose and secure with a clamp or a crimp-on hose ferrule. Sleeve-lock sockets connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.

Push-to-connect sockets join by firmly pushing the plug into the socket until you hear a click. Unlike sleeve-lock sockets, you don't have to slide back the sleeve. To disconnect, slide the sleeve on the socket forward until the plug ejects.

Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Brass is softer than other metals, so it’s easier to thread together. It has good corrosion resistance. Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All ARO plugs are compatible with any of the ARO sockets of the same coupling size, regardless of the pipe size or barbed hose ID.

Plugs are also known as nipples.

Plugs and sockets with a barbed end insert into plastic or rubber hose and secure with a clamp or a crimp-on hose ferrule.

Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Nickel-plated steel has good corrosion resistance. Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Made of 316 stainless steel, these fittings have the corrosion resistance to stand up to a wide variety of chemicals, as well as fuels, gasoline, and oils. To connect, slide the barbed end into plastic or rubber hose and secure with a clamp.

Adapters are also known as hose nipples; they adapt a barbed end to a threaded end.

Commonly used in low-pressure welding applications, these fittings connect downstream of your tank and pressure regulator. Slide the barbed end into rubber hose and secure with a crimp-on hose ferrule. Fittings are brass for good corrosion resistance.

Adapters let you adapt to a threaded end so you can connect welding hose to torches or pressure regulators. They consist of a barbed shaft with a rounded end that sits inside a threaded CGA nut (sold separately) so you can make a threaded hose connection.

Sets contain a crimping tool and a variety of fittings, nuts, and ferrules so you can connect pressure regulators, torches, and other components of your welding system. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance.

Barbed adapters let you adapt to a threaded end so you can connect welding hose to pressure regulators or torches. They consist of a barbed shaft with a rounded end that sits inside a threaded nut so you can make a threaded hose connection.

Barbed connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose. Slide the barbed end into welding hose and use a hose ferrule and the crimping tool to secure the fitting to hose.

Threaded connectors let you attach threaded welding hose to pressure regulators and torches.

Fittings with left-hand threads are identified with a notch in the nut.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.

Use these barbed fittings in low-pressure steam heating, humidification, and washdown applications up to 150 psi. Slide the barbed end into plastic or rubber hose and secure with a clamp. Also known as hose nipples, they adapt a barbed end to a threaded end.

Zinc-plated steel fittings have fair corrosion resistance and are stronger and more durable than other metal fittings. Aluminum fittings are lighter in weight than other metal fittings and have good corrosion resistance. 304 stainless steel fittings have very good corrosion resistance.

Fittings meet NSF/ANSI Standard 61 for drinking (potable) water. They are brass, which offers good corrosion resistance. Slide the barbed end into plastic or rubber hose and secure with a clamp or a crimp-on hose ferrule.

Fittings with a threaded pipe end are also known as hose nipples.

Hose connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.
