Product Description

The BMI USA 4021 is a lead-free brass threaded nipple designed for use in plumbing distribution systems where potable water safety compliance is required. Measuring 4 inches in diameter with a 3-inch length, this fitting connects threaded pipe sections in supply lines and branch connections. The red-finish brass construction provides corrosion resistance suited to water service applications. At 2.55 pounds, the fitting is sized for commercial and residential installations handled by licensed plumbers working with threaded iron or brass pipe systems.

This nipple is suited for residential and light commercial plumbing applications, including domestic water supply lines, branch connections, and service risers. Its lead-free brass construction makes it appropriate for installations subject to lead-free compliance requirements under applicable plumbing codes. Plumbing contractors and service technicians use this type of fitting when connecting or extending threaded pipe runs in potable water systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off and depressurize the water supply before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten — use a pipe wrench with a backup wrench on adjacent fittings to avoid stressing connected components.
