Bmi Usa 4130 Brass Nipple Lead Free 1/8 X 3 in

Product Description

The BMI USA 4130 is a lead-free brass close nipple designed for use in threaded pipe assemblies across plumbing, HVAC, and related mechanical systems. Machined from solid brass, this nipple provides a reliable threaded connection between fittings, valves, and other piping components. At 1/8-inch nominal pipe size and 3 inches in length, it fits tight-space installations where a short, straight extension is needed. The lead-free construction meets modern potable water compliance requirements. Installation is handled by licensed plumbers and pipefitters working on both new construction and service or retrofit projects.

This nipple is suited for residential and light commercial plumbing and hydronic systems. Its 1/8-inch NPT thread size makes it common in low-pressure supply lines, gauge ports, drain connections, and instrument taps. The red finish identifies the fitting in the field for quick visual sorting. It is compatible with standard NPT fittings and valves throughout the trade.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off the water supply and relieve system pressure before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Tighten to hand-tight plus the appropriate number of turns using a pipe wrench — do not overtighten brass fittings, as this can crack the fitting body.
