Merit Brass XNL101-1612 90 Deg Reducing Elbow 1x3/4 Fnpt

Product Description

The MERIT BRASS XNL101-1612 is a 90-degree reducing pipe elbow designed for threaded piping systems in plumbing, HVAC, and light industrial applications. Machined from brass with a rough finish, it connects a 1-inch nominal line to a 3/4-inch nominal line while making a right-angle direction change. The female National Pipe Taper (FNPT) end style on both ports creates a pressure-tight mechanical seal when assembled with tapered male threads. Rated at 125 lb, this fitting is suited for low-to-medium pressure service in water, gas, and air distribution lines where a simultaneous size reduction and directional change are needed in a single component.

This reducer elbow is commonly installed in residential and light commercial piping systems where supply lines transition from a larger trunk diameter to a smaller branch or fixture connection at a 90-degree offset. Typical applications include water supply headers, compressed air distribution, and low-pressure gas piping roughed in during new construction or retrofit service. Licensed plumbers and pipefitters are the primary installers, though HVAC and mechanical contractors also use brass FNPT fittings frequently in hydronic and refrigerant-adjacent piping work.

Key Features

• 90-degree turn and one-step size reduction in a single fitting, eliminating the need for a separate coupler and elbow
• FNPT threads on both ends for standard tapered pipe thread engagement
• 1 inch x 3/4 inch nominal sizing for common trunk-to-branch transitions
• 125 lb pressure rating suitable for water, air, and low-pressure gas service
• Brass construction provides corrosion resistance and good machinability for field trimming if needed
• Rough finish is compatible with thread sealant tape or pipe dope applied during assembly

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 125 lb threaded brass piping systems using NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the supply line completely before removing any existing fitting or threading in this elbow. Apply an appropriate thread sealant such as PTFE tape or pipe-thread compound to the male threads mating into these FNPT ports. Do not overtighten, as brass fittings can crack if excessive torque is applied.
