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 Noise, Filtration, and Flow Ratings

About Fire-Fighting Hose Threads

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.

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

Brass plugs and sockets 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.

Threaded Hose Fittings for Compressed Gas

Use these fittings to connect welding hose to pressure regulators and torches. They are also known as CGA (Compressed Gas Association) fittings. Fittings are brass for good corrosion resistance.

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.

Self-Draining Breather Vents

Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain. They have a silicone O-ring above the threads for a tight seal. Install them at the lowest point of the enclosure. Breather vents meet IP66 for protection in washdown environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.

Brass breather vents have good corrosion resistance.

Submersible Threaded Breather Vents

Nickel-Plated Brass

Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures. All have a hydrophobic and oleophobic filter membrane that blocks moisture and contamination from particle buildup.

Nickel-plated brass vents stand up to corrosive environments better than nylon and polycarbonate vents. They’re also durable, which means you won’t have to replace them as often.
