Bmi Usa 4945 Lead Free Brass Nipple 4.5 Inches

Product Description

The BMI USA 4945 is a lead-free brass threaded nipple designed for use in plumbing supply and distribution systems. At 4.5 inches in length with a 1/2 inch pipe thread, this nipple serves as a short extension or connector between threaded fittings, valves, and fixtures. Brass construction provides solid corrosion resistance and durability in both hot and cold water applications. The lead-free designation meets current potable water compliance requirements, making it suitable for installations where water quality standards must be maintained. Licensed plumbers and pipefitters are the primary installers of this fitting type.

This nipple is suited for residential and light commercial plumbing installations, including water supply lines, fixture connections, boiler trim, and hydronic piping. Its 4.5-inch body length makes it a practical close-to-medium extension where standard close or short nipples fall short. The 1/2 inch NPT thread pattern is one of the most common sizes in domestic plumbing, ensuring broad compatibility across standard fittings and valves found in typical plumbing work.
