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.

Universal-Thread Push-to-Connect Tube Fittings for Air and Water
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
Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads. With a nylon body and nickel-plated brass threads, these fittings are lighter than most metal fittings, and withstand corrosion better than plain brass threads. They also have a reusable gasket to guard against leaks. Connect the tube ends 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 known as instant fittings. All meet ISO 14743, which is an international standard for push-to-connect fittings for plastic tubing.

Wye-Shaped On/Off Valves with Garden Hose Threads
Convert one faucet into two, four, or five convenient outlets. Each outlet has individually operated shutoff valves.
Plastic valves are lighter than brass or zinc valves, and are durable enough to hold up to impacts and abrasion. They have good corrosion resistance.
Zinc valves have good corrosion resistance. Some also have a TPR rubber or plastic coating to protect your hands—the coating keeps valves from getting hot in the sun or cold in the winter.
Brass valves are softer than zinc and plastic, so they’re easier to thread together. They’re also corrosion resistant.
