Bmi Usa 4500 Lead Free Brass Nipple 3/4 X Close

Product Description

The BMI USA 4500 is a lead-free brass close nipple designed for threaded pipe assemblies in residential and light commercial plumbing systems. A close nipple consists entirely of threads with no unthreaded center section, allowing two fittings to be joined with minimal spacing between them. This nipple measures 3/4 inch in diameter with an overall length of 1 3/8 inches. Constructed from lead-free brass, it meets safe drinking water requirements and is suited for potable water, hydronic heating, and general-purpose fluid handling applications. Licensed plumbers and experienced pipefitters are the primary installers of this fitting type.

This close nipple is appropriate for use in residential water supply lines, boiler piping, and light commercial plumbing where compact thread-to-thread connections are required. Its 3/4 inch threaded ends accept standard NPT fittings including couplings, valves, tees, and elbows. The lead-free brass construction makes it a compliant choice for potable water systems in jurisdictions enforcing low-lead content regulations. It is a compact solution for situations where pipe spacing is tight and a standard nipple with a center hex would not fit.

Key Features

• 3/4 inch NPT threaded ends compatible with standard fittings and valves

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and relieve system pressure before removing any existing fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten, as brass threads can be damaged by excessive torque.
