Red Brass Hex Bushing 3/4" x 1/8

This red brass hex bushing reduces a 3/4 inch male NPT thread to a 1/8 inch female NPT thread. It is manufactured to ASTM B584, ASME B16.15 and ANSI B1.20.1 standards for Class 125 service. The fitting handles pressures up to 125 psi across a temperature range of -20 to 400 degrees F. It suits plumbing and light industrial piping systems.

For Thread Reduction Only

This bushing is intended for installers who need to step down pipe threads in a straight line. It will not work where a change of direction is required, so builders needing an elbow or tee should look elsewhere. Systems operating above 125 psi or outside the stated temperature limits need a different fitting class. California Proposition 65 warnings apply for cancer and reproductive harm.

Simple Threaded Installation

Installation requires only a wrench on the hex flats and suitable thread sealant for NPT connections. Over-tightening can crack the brass or strip threads, which is the most common fault. Ensure both mating threads are clean and undamaged before assembly. No special tools or soldering are needed for a proper seal.

Questions about this item

What pipe threads must already be present for this 3/4" MNPT x 1/8" FNPT bushing to connect?

The male end needs a 3/4" FNPT fitting and the female end needs a 1/8" MNPT pipe or component.

Will this Class 125 red-brass bushing hold up if I keep my existing steel pipe rated for the same pressure?

Yes, it meets ASTM B584 and ASME B16.15 at 125 psi, so it matches Class 125 steel fittings within that pressure limit.

How can I confirm the bushing is sealing properly after I thread it in?

Pressurise the line up to 125 psi and check for leaks; the ANSI B1.20.1 threads should seal with standard pipe compound.
