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.

Male
Threads
with Gasket

Temperature Range: 0° to 175° F
Tubing: Use with firm (Durometer 85A-100A) nylon plastic or polyurethane rubber
Specifications Met: ISO 14743

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types. They also have a reusable gasket to protect against leaks. The tube ends connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect them, push the release ring and pull the tubing out of the fitting. These fittings are sometimes called instant fittings. All meet ISO 14743, which is an international standard for push-to-connect fittings for plastic tubing.

Nano M8/Micro M12 Splitters

M12 Plug

M8 Socket × M8 Socket

4 Pole × 3 Pole × 3 Pole

Join two devices with M8 connectors to a single cord, distribution block, or I/O module with M12 connectors to save space and reduce the number of cords in industrial automation setups. Often used with sensors and switches, these splitters send or receive two signals through one connection. Rated IP65 and IP67, they’ll stand up to dust, low-pressure washdowns, and brief submersion.

Note: M12 plugs have an extra pin on the face that is not used.

5 Pole Plug × 5 Pole Socket × 5 Pole Socket

To save space and reduce the number of cords in industrial automation setups, these splitters join two devices with M12 connectors to a single cord, distribution block, or I/O module with M12 connectors. Often used with sensors and switches, they send or receive two signals through one connection. They’re rated IP67 to stand up to dust and brief submersion.

For the straight female socket connection, the 2nd pole is a contactless pole.
