What this fitting does

This malleable iron hex bushing provides a Class 150 threaded connection between 1/4 in and 1/8 in female NPT ports. It suits plumbing and pneumatic systems that require a durable, pressure-rated reducer for standard pipe threads.

Threads and class to verify

Confirm that both ports in your assembly use NPT threads and that the 150 class rating meets the system pressure requirements. The fitting has 18 threads on the larger end and 27 on the smaller end, so existing taps must match these counts.

No extras included

The product ships as a single component without sealant, gaskets or additional hardware. Installers must supply thread tape or pipe compound separately to ensure a leak-free joint.

Questions about this item

What comes with the 5P507 hex bushing and what must I buy separately?

The box contains the malleable iron Class 150 hex bushing with 1/4 in female NPT and 1/8 in female NPT threads; pipe sealant or tape and the mating pipe nipples are sold separately.

How do I choose between the available versions of this fitting?

The 5P507 is a single configuration — 1/4 in by 1/8 in FNPT both ends — so there are no alternative capacities or versions to select from.

What does the Class 150 rating mean when the bushing is installed in a real piping system?

Class 150 indicates the fitting is rated for 150 psi working pressure at ambient temperature, suitable for standard low-pressure water, air or oil lines.
