Merit Brass 2106-001 Red Brass Close Nipple 3/8 Inch Npt

Product Description

The MERIT BRASS 2106-001 is a close-pattern red brass nipple designed for tight-space pipe connections where no exposed thread length is needed between fittings. Manufactured to a seamless process and rated Schedule 40, this 3/8 inch nipple meets ASTM B687-88 and B456 material specifications. Red brass resists corrosion from water, heat, salt water, acids, minerals, and peaty soils, making it a reliable choice in systems where water chemistry is a concern. Licensed plumbers and pipefitters install this fitting across commercial and OEM applications where a durable, close-coupled threaded connection is required.

This nipple is suited for residential and commercial plumbing systems as well as OEM assemblies involving water, oil, gas, or steam service. Its relative metal softness allows threads to seat tightly against mating fittings, supporting leak-resistant joints with standard pipe dope or PTFE tape. The 3/8 inch size fits common branch lines, gauge ports, and instrument connections where space is limited and a close nipple eliminates unnecessary standoff. Packaged in quantities of 25 per box, this part is well suited for stocking and service-call kits.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply thread sealant or PTFE tape rated for the intended service medium before hand-tightening and then wrench-tightening to avoid cross-threading the soft brass threads. Follow applicable local plumbing codes and IFGC requirements for gas service applications.
