Reducing bushing for pipe transitions
The Banjo RB150-075 reducing bushing connects a 1-1/2 inch male NPT thread to a 3/4 inch female NPT thread. It is made from black polypropylene and rated to Schedule 80 dimensions. This fitting suits installers who need a durable, corrosion-resistant step-down in fluid-handling systems.
Thermals noise and power draw in normal use
The polypropylene body handles a temperature range from -20 degrees to 150 degrees Fahrenheit without degrading. It sustains a maximum working pressure of 150 psi in typical service. No moving parts or electrical components are present, so the fitting adds no noise or power draw to the installation.
How it fits into a build
The MNPT x FNPT thread pattern lets the bushing thread directly into existing pipe or fittings without adapters. Its Schedule 80 wall thickness provides mechanical strength for high-pressure lines while the polypropylene material resists chemical attack. The compact reducer frees up space compared to larger fabricated assemblies.

Questions about this item
How do I install the 1-1/2 MNPT x 3/4 FNPT bushing without cracking the polypropylene threads?
Hand-tighten the Schedule 80 bushing into the female port, then add one to two turns with a strap wrench; the tapered NPT threads seal by deformation, so over-torquing splits the black polypropylene body.
What replacement or maintenance does this Schedule 80 reducing bushing need over time?
Inspect the black polypropylene threads and sealing faces each season; replace the bushing if you see stress whitening, cracks, or weeping at the 150 psi rating limit.
At what temperature does this 150 psi rated fitting hit its limit first during sustained hot-fluid service?
The polypropylene material is rated to 150 degrees F; above that temperature the 150 psi pressure rating drops rapidly, so temperature is the first limiting factor.
