Merit Brass xnl101-64 4 in Fnpt 90 Deg Brass Elbow 125 Lb

Product Description

The MERIT BRASS xnl101-64 is a 90-degree brass pipe elbow designed for threaded piping systems in plumbing, industrial, and mechanical applications. Configured with female National Pipe Taper (FNPT) connections on both ends, this fitting redirects flow at a right angle within SCH 40/STD pipelines. Rated at 125 lb pressure class with a working pressure range of 125 to 200 psi, it handles a wide service temperature range of -20 to 400 degrees F. At 4 inches nominal size and weighing 7.7 pounds, this is a large-format fitting typically installed by licensed plumbers or pipefitters in commercial or industrial environments.

This elbow is suited for use in water supply, compressed air, steam, and general fluid piping systems where a 90-degree directional change is required at a 4-inch pipe junction. Its rough brass finish and FNPT end style make it compatible with standard threaded pipe assemblies operating within SCH 40/STD system design parameters. The fitting is lead-free, which supports compliance requirements in potable water applications where lead-free materials are mandated by local codes.

Compatibility

Designed as an OEM-style replacement or new-install fitting for 4-inch threaded pipe assemblies conforming to SCH 40/STD schedule and FNPT connection standards in plumbing and mechanical piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local mechanical codes. Depressurize and drain the piping system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to all male threads prior to assembly, and tighten to a firm, wrench-tight engagement without overtightening brass fittings. Inspect the connection for leaks after system pressure is restored.
