Bmi Usa 4568 Lead Free Brass Nipple 3/4x8

Product Description

The BMI USA 4568 is a lead-free brass threaded nipple designed for use in potable water supply systems, hydronic heating lines, and general plumbing applications. Machined from brass with a red finish, this nipple measures 3/4 inch in diameter and 8 inches in length, making it well suited for close-quarter connections where a longer nipple run is required. At 0.9 pounds, the fitting is solid and thread-ready for standard NPT connections. Lead-free construction meets modern potable water compliance standards, making it appropriate for installations governed by current plumbing codes.

This nipple is used in residential and light commercial plumbing systems wherever a 3/4-inch threaded connection is needed. Common install scenarios include water heater connections, boiler supply and return piping, fixture supply risers, and general pipe extensions. The 8-inch length provides enough run to clear obstructions or span short gaps between fittings and valves without requiring a union or coupling.

Key Features

• Lead-free brass construction meets potable water compliance requirements
• 3/4 inch diameter with standard NPT threading on both ends
• 8-inch length suits close-quarter and short-span piping runs
• Red finish for easy identification in mixed-material piping systems
• Solid brass body provides corrosion resistance in water and low-pressure gas applications

Compatibility

Designed as an OEM-style replacement or standard-use fitting compatible with 3/4-inch NPT threaded pipe systems in residential and commercial plumbing applications.

Installation Notes

This fitting is installed by licensed plumbers working under applicable IPC or local plumbing code requirements. Shut off the water supply and relieve system pressure before threading this nipple into any live line. Apply thread sealant tape or pipe dope to the male threads before assembly and tighten to a snug fit using a pipe wrench — avoid over-tightening, which can crack fittings or strip threads. Verify lead-free compliance requirements with the local authority having jurisdiction before installation in potable water service.
