Stainless Steel Threaded Union Specification

A Stainless Steel Threaded Union is a type of fitting used in piping systems to join two pipes or components that can be easily disconnected and reconnected without the need for welding or flanging. They are commonly used when frequent disassembly is required for maintenance, inspection, or repair. The union is designed with a male and female thread that allows for quick assembly and disassembly by simply screwing or unscrewing the parts.

Diameter Range	1/8″, 1/4″, 3/8″, 1/2″, 3/4″, 1″, 1 1/4″, 1 1/2″, 2″, 2 1/2″, 3″,4”
Thread Type	PF, PT, NPT, BSPP and BSPT
Stainless Steel	ASTM A182 F304/304L, F304H, F316/316L, F310, F317, F321

Pressure and Temperature Ratings

Stainless steel threaded unions can handle a range of pressures, from low-pressure applications to high-pressure systems, depending on the size and design of the union.

They are typically rated to handle pressures from 150 psi to 2000 psi (depending on the specific type), and can withstand a range of temperatures, generally between -50°F to 1000°F (though this can vary depending on the specific grade of stainless steel used).
