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.

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these fittings in a low-pressure pipe line. 304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Plugs with magnet attract metal debris that could otherwise damage your system.

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

Premium Low-Pressure Stainless Steel Threaded Pipe Fittings with Certification

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition. All fittings except 1/4" and 3/8" plugs and plugs with hex drive adhere to ANSI/MSS SP-114 standards for heat treating, material thickness, and marking. It’s the highest quality standard for Pressure Class 150 low-pressure stainless steel fittings. They also meet either ASTM A351 or A479 requirements for parts that will be used in pressure systems.

These stainless steel fittings are more corrosion resistant than steel fittings, and almost as strong. 316 stainless steel fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Extreme-Pressure Stainless Steel Threaded Pipe Fittings

With the strength to handle extreme pressures, these fittings can be used to connect equipment in hydraulic fluid lines. 316 stainless steel fittings have excellent corrosion resistance.

NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have a gasket to prevent leaks.

Open-Flow Quick-Disconnect Hose Couplings for Air and Water

Couplings allow for maximum flow because there’s no shut-off valve in the plug or the socket. 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 Open-Flow plugs are compatible with any of the Open-Flow sockets of the same coupling size, regardless of the pipe size. They are compatible with Hansen ST, Parker ST, and Perfecting E couplings.

Plugs are also known as nipples.

Sockets are sleeve-lock style. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug.

Brass plugs and sockets are softer than other metal plugs and sockets, so they’re easier to thread together. They have good corrosion resistance. 303 stainless steel plugs and sockets have very good corrosion resistance. They’re the best choice for high-humidity environments.

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

Warning: There is no valve in these couplings. Stop the air and water flow before you disconnect the line.

Impact-Resistant Thread-Lock Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Made of brass with a steel wing nut, these couplings are tough enough to handle occasional drops to concrete and frequent connections on dump truck, oil rigs, and other heavy duty equipment. Compared to push-to-connect couplings, these are threaded, so they're easier to connect when there's pressure in your line. The threads engage as you tighten the coupling, overcoming the pressure gradually rather than all at once. To limit fluid loss when you connect and disconnect them, they both have flat faces for a close fit, as well as shut-off valves that stop flow. This is why they’re known as flush-face and double shut-off couplings.

A complete coupling consists of a plug and socket (both sold separately). Sometimes referred to as wing-style couplings, the socket has a wing nut that makes it easy to tighten and loosen these couplings by hand. Make sure to thread the socket until it's covering the O-ring on the outside of the plug.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.

Warning: Stop the flow before you disconnect the line.

Quick-Disconnect Hose Couplings for Natural and LP Gas

1 1/4 Coupling Size

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket (sold separately or in a set) that connect and disconnect quickly. All of the natural and LP gas plugs are compatible with any of the natural and LP gas sockets of the same coupling size, regardless of the pipe size. Plugs and sockets are brass for good corrosion resistance. These couplings are rated ANSI Z21.41/CSA 6.9 for use with gas fuel appliances. CSA-US and CSA Certified, they also meet U.S. and Canadian safety standards.

Plugs are also known as nipples. They have a heat-sensitive fuse that will stop gas flow in the event of a fire.

Sockets have a shut-off valve that stops the flow when the coupling is separated, so gas won’t leak from the line. They are sleeve-lock style. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug.

NPTF (Dryseal) threads are compatible with NPT threads.

Warning: Stop the flow before you disconnect the line.
