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.

Low-Pressure Stainless Steel Threaded Pipe Fittings
Use these fittings in a low-pressure pipe line. 316 stainless steel fittings have excellent corrosion resistance.
Plugs with magnet attract metal debris that could otherwise damage your system.
NPTF (Dryseal) threads and NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.

- Pressure Class:
NPTF: 150 - Specifications Met:
Metric and BSPP: DIN 908 - Pipe Nipples and Pipe:
NPTF: Use Schedule 40 stainless steel - Flanges:
NPTF: Use Class 150 stainless steel

37° Flared Fittings for Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil
- Tubing: Use with seamless steel
- Specifications Met: SAE J514
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately. Fittings are zinc-plated steel for fair corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.
