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.

Extreme-Pressure Socket-Connect Stainless Steel Unthreaded Pipe Fittings
The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Pressure Class 6000. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Extra-Thick-Wall Stainless Steel Unthreaded Pipe

- For Use With: Air, Water, Hydraulic Fluid, Natural Gas, Steam, Oil
- Specifications Met: ASTM A312
- Fittings: Use Class 6000 or Schedule 160 stainless steel
With an extra-thick wall, this Schedule 160 pipe is the strongest stainless steel pipe we offer. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless, which provides a smooth interior for unrestricted flow.
304 stainless steel pipe has very good corrosion resistance. 316 stainless steel pipe has excellent corrosion resistance.

Extra-Thick-Wall Steel Threaded Pipe Nipples and Pipe
Extra-thick walls give this pipe excellent strength to handle high-pressure applications. It is also known as Schedule 160. Pipe is seamless, so it has a smooth interior for unrestricted flow. It is for use in noncorrosive environments.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Extra-Thick-Wall Galvanized Steel Threaded Pipe Nipples and Pipe
Also known as Schedule 160, this pipe has extra-thick walls for excellent strength. It has a galvanized finish that provides better corrosion resistance than our plain steel pipe. Pipe is seamless, so it has a smooth interior for unrestricted flow.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
