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.

Thick-Wall Stainless Steel Threaded Pipe Nipples and Pipe

Thick walls, also known as Schedule 80, give this pipe the strength to handle high-pressure applications. It is seamless so it has a smooth interior for unrestricted flow.

304 stainless steel pipe has very good corrosion resistance.

Straight reducers are also known as swage nipples.

For Use With: Air, Water, Hydraulic Fluid, Natural Gas, Oil, Steam
Specifications Met: MSS SP-95, ASTM A403
Fittings: Use Class 3000 stainless steel
Flanges: Use Use Class 300 or 600 stainless steel

Medium-Pressure Galvanized Iron and Steel Threaded Pipe Fittings

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Plugs with external hex drive and plugs with round body are also known as bull plugs; the center is hollow, which allows fluid to put pressure on the threads for a tight seal.
