Bmi Usa 4515 Brass Nipple 3/4 in X 1-1/2 in Lead Free

Product Description

The BMI USA 4515 is a lead-free brass nipple designed for threaded pipe connections in residential and light commercial plumbing systems. Machined from solid brass, this nipple measures 3/4 inch in diameter and 1.5 inches in length, making it a compact close or short nipple suitable for tight-space installations. The lead-free construction meets modern potable water safety requirements. Licensed plumbers and pipefitters install this fitting as part of supply-line assemblies, shutoff valve connections, and fixture risers. Its red finish aids identification in mixed-metal piping environments.

This nipple is used in water supply systems where a short brass threaded connection is needed between fittings, valves, or fixtures. Common applications include residential bathroom and kitchen plumbing, commercial lavatory connections, and light industrial fluid-handling assemblies where brass corrosion resistance is required. The 3/4-inch nominal pipe thread size fits standard NPT-threaded valves, couplings, and fittings widely used across plumbing trades.

Key Features

• Lead-free brass construction suitable for potable water service
• 3/4 inch nominal pipe size with 1.5-inch body length
• Standard NPT threads for compatibility with common threaded fittings and valves
• Red finish for quick visual identification
• Compact length suited for close-quarters installations

Compatibility

Designed as an OEM-style replacement or new-installation component for standard 3/4 inch NPT threaded plumbing assemblies in residential and light commercial water supply systems.

Installation Notes

Installation is performed by a licensed plumber following local plumbing codes and IPC guidelines. 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. Do not over-tighten brass fittings, as brass threads can be damaged by excessive torque.
