How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.Bronze fittings have better corrosion resistance and are stronger than brass and aluminum fittings.Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.

Stainless steel fittings have very good corrosion resistance. 303 stainless steel fittings won’t rust when exposed to water, making them good for areas that require frequent cleanings. Fittings that swivel until tightened rotate 360° for easy installation. Fittings with a threaded 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.

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

Steel fittings are stronger and more durable than other metal fittings. They should be used in noncorrosive environments. Zinc-plated steel fittings have slightly better corrosion resistance than unplated steel fittings. Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance. Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance.

Metal Cam-and-Groove Hose Couplings for Water

A complete coupling consists of a plug and a socket (both sold separately) that allow you to quickly connect and disconnect medium-to large-diameter hose lines. To connect, insert the plug into the socket and press the levers down. The levers fit snugly into the groove on the plug’s body and force the plug against the gasket to form a tight seal. To disconnect, lift both levers and pull out the plug.

Plugs with barbed end are also known as E adapters. Insert the barbed end into plastic or rubber hose and secure with a clamp.

Couplings with locking levers prevent accidental disconnection. The locks engage automatically when the coupling is connected. Press the locks simultaneously to disengage.

Straight sockets with barbed end are also known as C couplers. Insert the barbed end into plastic or rubber hose and secure with a clamp.

90° elbow sockets with barbed end are also known as CL couplers. Insert the barbed end into plastic or rubber hose and secure with a clamp.

Aluminum couplings are lighter in weight than brass plugs and sockets. They have good abrasion and corrosion resistance. Brass couplings are softer than aluminum plugs and sockets, so they’re easier to thread together. They have good corrosion resistance.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.

Plastic Cam-and-Groove Hose Couplings for Chemicals and Petroleum

Made of plastic, these couplings are lighter in weight than metal cam-and-groove hose couplings, yet have the chemical resistance to withstand gasoline and other harsh substances. A complete coupling consists of a plug and a socket (both sold separately) that allow you to quickly connect and disconnect medium-to large-diameter hose lines. To connect, insert the plug into the socket and press the levers down. The levers fit snugly into the groove on the plug’s body and force the plug against the gasket to form a tight seal. To disconnect, lift both levers and pull out the plug.

Plugs with barbed end are also known as E adapters. Insert the barbed end into rubber hose and secure with a clamp.

Sockets with locking levers prevent accidental disconnection. The locking pins engage automatically when the coupling is connected. Press the locking pins simultaneously to disengage.

Sockets with barbed end are also known as C couplers. Insert the barbed end into rubber hose and secure with a clamp.

Nylon plugs and sockets have better strength than PVDF plugs and sockets. They have good corrosion and chemical resistance to handle gasoline and fuel applications.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.

Barbed Hose Fittings for Coolant

Fittings have a barbed end that slides into rubber hose and secures with a clamp. All are nylon, which is lightweight with excellent impact and abrasion resistance. They have good corrosion resistance.

Fittings with a threaded pipe connection are also known as hose nipples. They adapt a barbed end to a threaded end.

Cam-and-Groove Hose Couplings for Abrasive Material

Made of ductile iron, these couplings are tough enough to handle sand, cement, and other abrasive solids and slurries. They resist impact and wear better than aluminum and brass couplings. Use their cam-and-groove fittings to quickly connect and disconnect medium- to large-diameter hose lines. To connect, insert the plug into the socket and press the levers down. The levers fit snugly into the groove on the plug’s body and force the plug against the gasket, forming a tight seal. To disconnect, lift both levers and pull out the plug. A complete coupling consists of a plug and a socket (both sold separately).

Plugs with barbed end are also known as E adapters. Insert the barbed end into plastic or rubber hose and secure with a clamp.

Sockets with barbed end are also known as C couplers. Insert the barbed end into plastic or rubber hose and secure with a clamp.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings

Temperature Range: See Gaskets

The smooth finish inside these fittings makes it easy to remove product residue. Also known as aseptic and tri-clamp fittings, they connect with a gasket, a clamp, and another quick-clamp fitting for a fast and easy way to access your line. The pressure rating of the fitting will vary depending on the clamp you choose, and the temperature rating will vary based on the gasket material you choose.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

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

Gaskets

Buna-N gaskets are oil resistant. EPDM gaskets resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets stand up to fuel, oil, and acid condensates. PTFE gaskets withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.
