Nomaco PEBFRED21 Concentric Reducer 2x1 Inches

Product Description

The NOMACO PEBFRED21 is a concentric reducer fitting designed to transition pipe or tubing from a 2-inch diameter to a 1-inch diameter along a shared centerline. Concentric reducers maintain axial alignment between the two pipe sections, making them the standard choice when flow must remain centered and balanced through the transition. This fitting is used in piping systems across HVAC, plumbing, and related mechanical trades. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers.

The PEBFRED21 is suited for residential and light commercial piping installations where a reduction from 2 inches to 1 inch is required. Its concentric design keeps both pipe ends on the same centerline, which is especially important in horizontal runs and in systems where flow symmetry affects performance. This fitting is a straightforward, workmanlike solution for pipe transitions in mechanical rooms, equipment connections, and distribution lines.

Key Features

• Concentric design maintains shared centerline between inlet and outlet for balanced flow
• Transitions from 2-inch pipe to 1-inch pipe in a single fitting
• Suitable for use in HVAC, plumbing, and mechanical piping applications
• OEM-style replacement or new-installation fitting for standard pipe reduction requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for piping systems requiring a concentric reduction from 2 inches to 1 inch.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or local mechanical codes. Depressurize and drain the piping system fully before removing any existing fittings or installing this reducer. Ensure pipe ends are clean, deburred, and properly prepared before making the connection. Verify that the fitting material and joining method are compatible with the fluid, pressure, and temperature conditions of the system.
