Brass Union for 3/8" FNPT Piping

This brass union connects two sections of 3/8 inch FNPT pipe in residential or light-commercial plumbing systems. The Class 150 rating supports a maximum pressure of 1200 psi. It is intended for installers who need a removable joint that can be taken apart without cutting the pipe. Buyers who require a permanent soldered or welded connection will not use this fitting.

Class 150 Pressure Rating at 1200 psi

The single specification that decides fit is the Class 150 designation combined with a 1200 psi maximum pressure limit. This rating determines whether the union can handle the system’s working pressure without leaking or deforming. Verify that your application stays within this limit before installation. Systems exceeding 1200 psi require a higher-class fitting.

Temperature Range -65 to 250 Degrees F

Under sustained load the brass body operates continuously between -65 and 250 degrees Fahrenheit. The material maintains its seal and structural integrity across this span without the softening or embrittlement seen in short-term extremes. California Proposition 65 warnings apply for cancer and reproductive-harm substances present in the alloy.
