Merit Brass XB111-06 Brass Pipe Coupling 3/8 in Fbspt Class 125

Product Description

The MERIT BRASS XB111-06 is a Class 125 brass pipe coupling designed for threaded pipe connections in a wide range of plumbing and mechanical piping systems. The coupling features female British Standard Pipe Taper (FBSPT) threads on both ends, accepting 3/8 inch threaded pipe. At 0.14 pounds, it is a compact, lightweight fitting suited for joining two sections of pipe in a straight run. Brass construction provides reliable corrosion resistance and durability in typical fluid and gas service applications where Class 125 fittings are specified.

This coupling is used in residential and light commercial plumbing, HVAC piping, compressed air lines, and general mechanical systems where 3/8 inch threaded connections are required. The FBSPT x FBSPT configuration makes it appropriate for joining threaded pipe where a straight coupling is needed to extend or repair an existing run. Licensed plumbers and pipefitters are the primary installers in regulated applications.
