Product Identity

The Legend Valve 350-647 is a black hex bushing with 4" x 2" FNPT/MNPT threads. It connects a larger female pipe thread to a smaller male pipe thread in plumbing systems. This new fitting is intended for installers who need a durable transition between different pipe sizes.

Suitable Applications

This bushing suits plumbers and maintenance technicians reducing a 4" female port to a 2" male connection in water, gas or oil lines. It is not for buyers who need a straight coupling, a different thread standard or a fitting rated for pressures beyond the manufacturer's published limits.

Installation Notes

The hex head allows tightening with a standard pipe wrench. Apply appropriate thread sealant to the male threads before assembly to prevent leaks. Over-tightening can crack the casting, so stop when the joint feels snug and test for drips before putting the system into service.

Questions about this item

Which pipe sizes does the 4" x 2" hex bushing connect?

The 4" x 2" hex bushing joins a four-inch female NPT thread to a two-inch male NPT thread, letting you step down from a larger pipe to a smaller one.

Can the black hex bushing be installed on existing steel pipe threads?

Yes, the bushing uses standard NPT threads that mate with existing steel pipe of matching size, so it fits onto the threads you already have.

How can I confirm the bushing is sealed correctly after tightening?

After assembly, pressurise the system and check the joint for leaks; a properly seated NPT connection with thread sealant will hold pressure without weeping.
