  • Red brass resists corrosion for longer service life

3/4 in Female NPT Brass Union

This Value Brand union coupling joins two 3/4 in Female NPT threaded pipes in a straight line. The red brass body is rated to Class 125 with a maximum operating pressure of 200 psi. It suits water, air and compatible fluid lines in residential or light commercial plumbing systems.

Installation checks for 3/4 in NPT threads

Verify that both mating ports are 3/4 in Female NPT and that the thread sealant you plan to use is approved for brass fittings. Confirm the system pressure will not exceed 200 psi and that the fluid is compatible with red brass. California Proposition 65 warnings apply because the fitting contains a listed chemical.

Replaces worn 3/4 in brass unions

Use this coupling when an existing 3/4 in union leaks, cracks or corrodes beyond safe service. The jump is worth it if the old fitting cannot hold 200 psi or if thread damage prevents a reliable seal. It is not for installations that require a different thread standard, a higher pressure class or a non-brass material.

Questions about this item

What is included with the Value Brand 6RDA6 union and what must be purchased separately?

The box contains the red brass union with 3/4 in female NPT threads on both ends; pipe sealant or tape and the mating pipe nipples are not included.

How do I decide between the Class 125 and other pressure classes for this 3/4 in union?

Class 125 designates a 200 psi maximum operating pressure at ambient temperature; choose it when your system pressure stays at or below that rating.

What does the 200 psi rating mean once the union is installed in a plumbing line?

It is the maximum continuous operating pressure the brass body and threads are rated to hold at room temperature; system pressure must not exceed 200 psi.
