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.

Threaded Hose Fittings for Hydraulic Fluid
Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system.
Zinc-plated steel fittings are stronger and more durable than stainless steel fittings. They have fair corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Fittings that swivel until tightened rotate for easy installation.
NPTF (Dryseal) threads are compatible with NPT threads. NPSM (National Pipe Straight Mechanical) female threads are compatible with male NPT and NPTF threads.

Push-to-Connect Tube Fittings for Air
UN/UNF (SAE)
Male Threads with Gasket
- Temperature Range: 0° to 170° F
- Tubing: Use with firm (Durometer 95A-45D) polyethylene plastic or polyurethane rubber
- Specifications Met: ISO 14743, except polybutylene plastic fittings
Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance.
Identification rings (sold separately) snap over the release ring so you can color-code your lines.
Clips (sold separately) align and organize your tubing and fittings.
Fittings with PTFE thread sealant offer extra protection against leaks.
Metric male threads have either a gasket or a thread sealant to protect against leaks. BSPP and UN/UNF (SAE) male threads have a gasket to protect against leaks. UN/UNF (SAE) threads are also known as O-ring boss threads.

- 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.

- Tubing: Use with hard (Durometer 65D) nylon plastic
- Specifications Met: D.O.T. FMVSS 571, SAE J1131, SAE J2494-1, SAE J2494-3
Suitable for use in air brake lines, these fittings meet Department of Transportation FMVSS 571 safety standards for low-temperature applications. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Fittings have a built-in tube support that slips inside the tubing to prevent it from collapsing. To disconnect, push on the release ring and pull the tubing out of the fitting. They have good corrosion resistance.
