Bmi Usa 4420 Brass Nipple Lead Free 1/2 X 2 Inches

Product Description

The BMI USA 4420 is a lead-free brass threaded nipple designed for use in potable water, plumbing, and fluid distribution systems. At 1/2 inch nominal diameter and 2 inches in length, this short nipple provides a compact threaded connection between fittings, valves, and pipe assemblies. The red finish aids quick visual identification on the job. Constructed from solid brass, it delivers reliable corrosion resistance in both hot and cold water applications. Licensed plumbers and pipefitters install this fitting as part of roughing-in work, repair, and retrofit projects across residential and light commercial systems.

The BMI USA 4420 brass nipple is suited for residential and light commercial plumbing installations where a short threaded connection is required. Typical applications include connecting shutoff valves, ball valves, boiler components, water heaters, and manifold assemblies. Its lead-free brass construction meets requirements for use in potable water systems. The 1/2 inch NPT thread size is one of the most common in residential plumbing, making this nipple a practical stock item for service calls and new installations alike.

Installation Notes

Installation is performed by a licensed plumber or qualified 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 wrench-tight per standard practice — do not overtighten brass fittings, as overtightening can crack the fitting body.
