1-1/4" MNPT x 1/2" FNPT Galvanized Hex Bushing

This galvanized malleable iron hex bushing connects a 1-1/4 inch male NPT thread to a 1/2 inch female NPT thread. It is rated for Class 150 service and suits plumbing installations that require a durable, corrosion-resistant transition between different pipe sizes.

Installation uses the external hex for wrench

Apply thread sealant to the male NPT threads before tightening the bushing into the female fitting. Over-tightening can crack the malleable iron body or strip the tapered threads, so stop when the joint feels solid and leak-free.

Class 150 rating defines the pressure limit

The fitting is designed for standard Class 150 piping systems and should not be used where pressures exceed that rating. California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and reproductive harm, so handle with appropriate precautions.

Questions about this item

How can I confirm the 1-1/4" MNPT x 1/2" FNPT galvanized hex bushing is sealing correctly after installation?

Pressurise the line and check the NPT threads at both the 11 1/2 TPI male end and the 14 TPI female end for leaks; a dry joint confirms the Class 150 malleable iron fitting is working as intended.

What comes in the box with the ZORO SELECT 5P886 hex bushing and what must I supply myself?

The package contains only the single galvanized hex bushing; you must provide pipe thread sealant or tape and the mating 1/2" FNPT and 1-1/4" MNPT pipe sections separately.

Which version of the galvanized hex bushing should I choose for a Class 150 malleable iron system?

Select the ZORO SELECT 5P886 model with 1-1/4" MNPT x 1/2" FNPT NPT threads, 11 1/2 TPI on the male side and 14 TPI on the female side, rated for Class 150 service.
