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.

About Fire-Fighting Hose Threads

Low-Pressure Brass and Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance. Fittings rated for use with drinking water meet NSF/ANSI 61 safety standards.

Union connectors separate into three pieces so you can access your line without unthreading pipe connections.

Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration.

Female x male 90° elbow adapters are also known as street elbows.

Right-angle tees are also known as run tees. Inline tees are also known as branch tees.

NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.

Standard-Wall Brass Threaded Pipe Nipples and Pipe

Also known as Schedule 40, this pipe is for use in low-pressure flow applications. It is brass, which offers good corrosion resistance. Pipe is seamless and has a smooth interior for unrestricted flow.

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.

Also known as Pressure Class 150 flanges, these are designed for low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges have good corrosion resistance. To adhere to safety standards for drinking water systems, use flanges that meet NSF/ANSI 61.

Easy-Fit Barbed Hose Fittings for Air and Water

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp.

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.

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 male threaded end are also known as F adapters.

Plugs with female threaded end are also known as A adapters.

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.
