Galvanized Hex Bushing 3" MNPT x 1-1/2" FNPT

This galvanized hex bushing connects a 3 inch male NPT thread to a 1-1/2 inch female NPT thread. It is made from cold rolled steel with a Class 150 malleable iron construction. The fitting suits plumbing systems requiring a secure reduction between different pipe sizes.

Class 150 rating under sustained pressure

The Class 150 rating indicates the pressure capability for continuous service at standard temperatures. Galvanized coating resists corrosion during extended exposure to water or air. Malleable iron construction maintains structural integrity without cracking under prolonged mechanical stress.

Check thread compatibility and chemical warnings

Verify that your existing piping uses NPT threads matching the 8 and 11 1/2 thread specifications. Confirm the galvanized finish is suitable for your fluid type. Note the Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.

Questions about this item

Does the Class 150 rating limit the pressure this galvanized hex bushing can handle in a continuously running system?

Class 150 indicates a pressure class for malleable iron fittings, suitable for standard water, oil, and gas service at moderate pressures and temperatures.

What pipe thread sealant or tape is required on the 3-inch male NPT end with 8 threads per inch to ensure a leak-free joint?

Apply PTFE tape or pipe thread compound approved for NPT threads on the male end before assembly to seal the tapered joint.

Will the galvanized coating on this malleable iron bushing react with older black iron pipe threads when joined?

Galvanized and black iron NPT threads mate mechanically; the zinc coating does not prevent threading but dielectric unions are used if corrosion between dissimilar metals is a concern.
