3/8 in Female NPT Brass Union

This brass union connects two 3/8 in female NPT threads in plumbing and hydronic systems. Rated for 200 psi maximum operating pressure, it suits water lines and similar fluid circuits. The Class 125 fitting is intended for installers needing a straight-threaded joint without flaring tools.

Installation notes

Thread each end onto matching 3/8 in female NPT connections using pipe sealant or tape rated for brass. Hand-tighten then finish with a wrench; over-tightening can strip the relatively soft red-brass threads. Ensure both mating surfaces are clean to avoid leaks at the joint.

Compatibility check

Verify that your existing piping uses 3/8 in female NPT threads and that system pressure will not exceed 200 psi. Confirm the fluid is compatible with brass alloys and that local codes accept Class 125 fittings for the application. This product is restricted from sale in California due to Proposition 65 chemical content.
