- 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.

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.

Standard-Wall Galvanized Steel Threaded Pipe Nipple and Pipe Assortments

- For Use With: Air, Steam, Oil, Water, Natural Gas
- Specifications Met: ASTM A733, ASME B1.20.1, ASTM A53
- Fittings: Use Class 125 or 150 galvanized iron and galvanized steel
- Flanges: Use Class 150 steel
Assortments contain threaded pipe in various lengths. The galvanized finish on this pipe provides fair corrosion resistance. Also known as Schedule 40, it is designed for low-pressure applications. Pipe is welded, so there is a weld bead on the inside.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

High-Pressure Steel Threaded Pipe Cap and Plug Assortments



The heavy duty caps and plugs in these assortments come in various sizes and stand up to high-pressure flow applications. Made of steel, they’re for use in noncorrosive environments. You can take them apart as needed for maintenance and repair because they’re threaded.

Standard-Wall Brass Threaded Pipe Nipple and Pipe Assortments

- For Use With: Air, Drinking Water, Natural Gas, Oil, Steam, Water
- Specifications Met: ASME B1.20.1, ASTM B687, Fed. Spec. WW-N-351C, NSF/ANSI 61
- For Fitting Class: 125
Keep various lengths of brass pipe on hand for applications requiring good corrosion resistance. The pipe in these assortments is threaded, so you can take apart its connections for maintenance and repair. They’re Schedule 40, so they should be used in low-pressure applications. This pipe is seamless, so it has a smooth interior for unrestricted flow, and it’s stronger than welded pipe.
Fully threaded pipe nipples are also known as a close nipple; they are threaded on each end to the center.
