Bmi Usa 4840 Brass Nipple 1-1/2 X 4 Inch Lead Free

Product Description

The BMI USA 4840 is a lead-free brass threaded nipple designed for use in plumbing supply and distribution systems. This close-tolerance fitting connects threaded pipe runs and provides a durable, corrosion-resistant joint in potable water, hydronic, and general plumbing applications. At 4 inches in length and 1-1/2 inches in diameter, it fits standard NPT threaded pipe systems. The brass construction meets lead-free requirements, making it suitable for installations where contact with drinking water is a factor. Licensed plumbers and pipefitters are the primary installers of this fitting type.

This nipple is suited for residential and light commercial plumbing installations where a short-length threaded pipe extension or connection is needed between fittings, valves, or equipment. Common applications include water supply lines, boiler piping, and mechanical room rough-in work. The 4-inch length provides adequate reach for offset connections in tight installations without requiring field-cut pipe. The red finish identifies the fitting as a standard catalogued product in the BMI Canada line, cross-referenced as BMI Canada part 04840.

Installation Notes

Shut off the water supply and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly.
