Ipex 400300prb Pvc Sch40 Conduit Reducer Bushing 4x3 in

Product Description

The IPEX 400300prb is a PVC Schedule 40 conduit reducer bushing designed to transition between a 4-inch bell end and a 3-inch spigot end in electrical conduit systems. This fitting allows installers to step down conduit run sizes within the same Schedule 40 PVC system without the need for additional adapters. Constructed from non-metallic PVC, it resists corrosion and moisture in both above-grade and below-grade conduit applications. Licensed electricians and electrical contractors install this fitting as part of raceway systems governed by NEC requirements for rigid nonmetallic conduit.

This reducer bushing is suited for use in residential and commercial PVC conduit installations where a 4-inch conduit must transition to a 3-inch conduit. Typical applications include underground feeder runs, site lighting conduit systems, service entrance raceways, and other Schedule 40 PVC conduit assemblies. The bell-to-spigot configuration allows the bushing to seat directly onto a Schedule 40 spigot and accept a Schedule 40 bell, maintaining consistent inside diameter clearances for wire and cable pull-through.

Key Features

• Bell x Spigot end configuration for direct Schedule 40 PVC conduit connections
• 4-inch inlet to 3-inch outlet reduction in a single fitting
• Non-metallic PVC construction resists corrosion, moisture, and soil contact
• Schedule 40 wall thickness compatible with standard PVC conduit solvent-weld fittings

Compatibility

Designed as an OEM-style replacement and standard fitting for Schedule 40 PVC electrical conduit systems requiring a 4-inch to 3-inch bell-to-spigot reducer bushing.

Installation Notes

Installation is performed by licensed electricians in accordance with applicable NEC articles governing rigid nonmetallic conduit. De-energize all circuits and confirm no conductors are present in the conduit run before cutting or joining sections. Use approved PVC conduit solvent cement and primer per manufacturer instructions for a watertight, code-compliant joint. Allow full cure time before pulling wire through the assembly.
