Description
304 Stainless Steel 150# Threaded Union - SP114
Charman 304 Stainless Steel SP114 Threaded Unions provide a convenient way to join compatible threaded piping components while allowing the connection to be separated without rotating the adjoining pipe. Manufactured from 304 stainless steel, these unions are available in nominal sizes from 1/8" through 3" for plumbing, industrial, process, maintenance, and general piping applications.
The SP114 Union uses a multi-piece threaded design that allows the fitting to be assembled or disconnected at the union connection point. This makes it useful where equipment, valves, or sections of threaded piping may need future service, replacement, or removal.

What Is an SP114 Threaded Union?
A 304 stainless steel SP114 threaded union is a multi-piece fitting designed to connect two compatible threaded piping components while allowing the joint to be separated when service or removal is required.
Unlike a standard coupling, which typically requires one piping component to rotate during installation or removal, a union can be separated at the union nut. This makes the fitting especially useful near equipment, valves, pumps, and other components that may require maintenance.
