Hex Bushing Malleable Iron Class 150
This ZORO SELECT hex bushing connects a 3/4 in male NPT thread to a 1/2 in female NPT thread. It is built from malleable iron rated for Class 150 service. Plumbers and maintenance technicians use it to step down pipe sizes in water, air or oil lines. The fitting arrives new and ready for thread sealant.
Class 150 pressure rating and NPT threads
The Class 150 rating provides adequate headroom for standard low-pressure plumbing and compressed-air systems. The 14 threads per inch on each end create a reliable seal when assembled with appropriate tape or paste. It runs out of capacity in high-pressure hydraulic circuits or steam lines that exceed the Class 150 limit. The malleable iron body resists cracking under normal mechanical stress.
Fits standard NPT pipe assemblies
The bushing threads directly into any 3/4 in female NPT port and accepts a 1/2 in male NPT nipple or valve. No special tools are required beyond a standard hex wrench for the bushing body. It frees up space compared with a coupling plus nipple combination because the reduction occurs in a single fitting. The item ships directly from Zoro and orders of $75 or more ship free.

Questions about this item
Will the 3/4 in MNPT thread connect to the older 1/2 in FNPT fitting I already have?
Yes, the bushing reduces from 3/4 in male NPT to 1/2 in female NPT so it bridges those two sizes directly.
How can I verify the Class 150 rating is holding pressure after installation?
Pressurise the system to its working limit and check the joint for leaks; a sound malleable iron Class 150 bushing will show no seepage at the threads.
Does the 5P515 package include thread sealant or must I buy it separately?
Only the hex bushing is supplied; pipe thread sealant or tape is not included and must be purchased separately.
