Merit Brass XB101-04 Brass 90 Elbow 1/4 in Threaded Class 125

Product Description

The MERIT BRASS XB101-04 is a 90-degree brass pipe elbow designed for threaded plumbing and piping assemblies. It features female British Standard Pipe Taper (FBSPT) connections on both ends, allowing a direct inline direction change without the need for additional adapters. Rated at Class 125, this fitting is built for low-to-medium pressure service in water, air, and general fluid systems. The 1/4-inch fitting size makes it well suited for smaller-diameter branch lines and instrumentation runs. Licensed plumbers and pipefitters are the typical installers for this type of fitting in residential and light commercial environments.

This elbow is used wherever a 90-degree change of direction is needed in a 1/4-inch threaded pipe run. Common applications include plumbing supply lines, compressed air distribution, hydraulic lines, and HVAC condensate or refrigeration accessory piping. The FBSPT x FBSPT configuration fits directly onto male-threaded pipe ends or fittings. It is appropriate for residential and light commercial installations where Class 125 pressure ratings are acceptable for the service conditions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free joint. Do not overtighten, as brass fittings can crack under excessive torque.
