Merit Brass C101-12 Brass 90 Elbow 3/4 Inch Fnpt Class 125

Product Description

The MERIT BRASS C101-12 is a Class 125 brass pipe 90 degree elbow fitting designed for threaded pipe assemblies in plumbing, HVAC, and light industrial applications. With female NPT (FNPT) connections on both ends, the fitting accepts standard tapered male pipe threads and creates a secure, leak-resistant 90 degree directional change in a piping run. The 3/4 inch size suits common branch and main line work. Licensed plumbers and pipefitters handle this type of fitting as routine stock. Brass construction offers good corrosion resistance and reliable performance across a wide range of fluid-handling service conditions.

This fitting is used in residential and light commercial piping systems where a threaded right-angle connection is needed. Typical applications include water supply lines, gas distribution piping where brass is code-accepted, hydronic heating loops, and compressed air distribution. The FNPT x FNPT configuration makes it compatible with standard NPT male-threaded pipe nipples and fittings throughout the system. It is sold individually, making it suitable for both single-fitting repairs and bulk project procurement.

Key Features

Compatibility

Designed as an OEM-style threaded replacement fitting for 3/4 inch NPT piping systems using standard Class 125 brass fittings.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the piping system completely before removing any existing fitting. Apply an approved thread sealant or PTFE tape to the male threads being engaged — do not apply sealant to the female threads of this fitting. Tighten to hand-tight plus the number of turns specified by the thread sealant manufacturer; avoid overtightening, which can crack brass fittings. Verify local code requirements, including IPC and IFGC provisions, before using brass fittings in gas service.
