Merit Brass XB103-04 Brass 90 Street Elbow 1/4 in

Product Description

The MERIT BRASS XB103-04 is a 90-degree street elbow fitting machined from brass, designed for threaded pipe connections in plumbing, HVAC, and light industrial systems. It features female British Standard Pipe Taper (FBSPT) on one end and male British Standard Pipe Taper (MBSPT) on the other, allowing a direction change directly at a fitting or valve without a separate nipple. Rated Class 125, this elbow is suited for low-to-medium pressure service in water, air, and compatible fluid applications. The 1/4 inch fitting size makes it a common choice for instrumentation lines, gauge ports, and branch connections. Licensed plumbers and HVAC technicians are the typical installers.

This street elbow is used in residential and light commercial plumbing and HVAC piping where a 90-degree direction change is needed at a threaded connection point. The FBSPT x MBSPT end configuration allows it to thread directly into a tee, valve, or fitting body, eliminating an extra coupling. At 1/4 inch, it is frequently found on gauge connections, air line branches, water supply take-offs, and boiler trim piping. Its compact brass construction handles typical shop-air and domestic water pressures within Class 125 ratings.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4 inch threaded brass pipe systems rated Class 125, including water, air, and compatible low-pressure fluid applications.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician following applicable IPC or IFGC guidelines for threaded pipe joints. Shut off and depressurize the line before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque brass fittings, as the material is softer than steel and the threads can be damaged.
