The Merit Brass NIPBR18-412 is a seamless brass pipe nipple designed for use in plumbing, HVAC, and industrial piping systems where a reliable threaded connection is required. This nipple measures 1/8 inch in nominal size and 4-1/2 inches in length, making it a practical close-to-medium length fitting for tight or standard spacing applications. It features male NPT threads on both ends, allowing it to thread directly into female NPT fittings, valves, tees, elbows, and other standard pipe components. The MNPT configuration is one of the most common thread types used in North American plumbing and HVAC work, ensuring broad compatibility across job sites and equipment types. Manufactured using a seamless process, this nipple has no longitudinal weld seam, which improves pressure resistance and reduces potential leak points. The Schedule 40 and standard wall thickness rating means it meets widely accepted strength requirements for low to moderate pressure service lines. Brass is the material of choice here because it resists corrosion in water and gas service, handles a wide temperature range, and machines cleanly for consistent thread quality. Trade professionals such as plumbers, pipefitters, HVAC technicians, and mechanical contractors rely on brass nipples like this one for water supply lines, compressed air systems, natural gas connections, steam service, and instrumentation piping. This nipple is domestically produced, which supports consistent quality control and material traceability. The red color coding used on Merit Brass fittings helps with quick identification on the job. Whether used as a replacement part or in new construction, the NIPBR18-412 delivers dependable performance in a standard size that fits easily into any fitting inventory.
The Merit Brass NIPBR18-412 is a domestically made, seamless brass pipe nipple with MNPT ends, built to Schedule 40 and standard wall specifications for reliable performance in plumbing, HVAC, and industrial piping applications.
