Georg Fischer 829-420FB Sch 80 Pvc Reducing Coupling 4x2 in

Product Description

The GEORG FISCHER 829-420FB is a Schedule 80 PVC bushed reducing coupling designed for pressure-rated plumbing and industrial piping systems. It transitions from a 4-inch socket to a 2-inch socket (SxS) in a single fitting, eliminating the need for a separate bushing insert in many applications. The Schedule 80 wall thickness provides higher pressure tolerance and greater impact resistance compared to Schedule 40, making it appropriate for demanding service conditions. Licensed plumbers and pipefitters install this fitting where a straight-run reduction is required without an additional adapter.

This bushed reducing coupling is used in residential, commercial, and light industrial plumbing systems where PVC pressure piping is specified. Typical applications include cold-water supply lines, irrigation mainlines, chemical-drainage headers, and recirculation systems where a reduction from 4 inches to 2 inches is needed in a compact inline configuration. The socket-by-socket end configuration accepts standard Schedule 80 PVC pipe on both ends and is joined using PVC solvent cement per manufacturer and code requirements.

Key Features

• Schedule 80 PVC construction for higher pressure ratings versus Schedule 40
• 4-inch x 2-inch socket-by-socket (SxS) bushed reducing configuration in one fitting
• PVC material offers corrosion resistance and compatibility with a wide range of fluids
• Overall length of 4.94 inches supports compact inline installation
• Suitable for use in pressure-rated cold-water and industrial piping systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 PVC piping systems using 4-inch and 2-inch pipe in socket-joint configurations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable plumbing codes, including IPC and local authority requirements. Depressurize and drain the piping system completely before cutting or removing any existing fittings. Both pipe ends and fitting sockets must be cleaned, primed, and joined using solvent cement rated for Schedule 80 PVC. Do not apply heat or use threaded adapters directly on the socket ends, as this can compromise fitting integrity.
