Value Collection 839-422 Pvc Reducer Bushing 4x3 in Sch 80

Product Description

The VALUE COLLECTION 839-422 is a Schedule 80 PVC reducer bushing designed to transition pipe runs from a 4-inch male iron pipe thread (MIPT) connection down to a 3-inch female iron pipe thread (FIPT) connection. Built from rigid PVC, this bushing handles the demands of industrial, commercial, and plumbing systems where a durable, corrosion-resistant threaded fitting is required. Schedule 80 wall thickness provides greater pressure capacity compared to Schedule 40, making it suitable for higher-demand applications. Licensed plumbers and pipefitters are the typical installers of this type of threaded reducer fitting.

This reducer bushing is used wherever a pipe run requires a threaded step-down from 4 inches to 3 inches in diameter. Common applications include water distribution, chemical handling, irrigation systems, and industrial plumbing where PVC is an approved material. The MIPT x FIPT end configuration allows it to thread directly into a female-threaded pipe or fitting on the larger end and accept a male-threaded pipe on the smaller end, eliminating the need for additional coupling hardware at the transition point.

Key Features

• Schedule 80 PVC construction for higher pressure rating compared to standard Schedule 40 fittings
• MIPT x FIPT threaded end connections for straightforward installation into existing threaded systems
• 4-inch to 3-inch reduction in a single fitting, minimizing components at the transition
• PVC material provides corrosion resistance suitable for water and many chemical service applications
• Compact, lightweight design at 0.18 pounds for easy handling during installation

Compatibility

Designed as an OEM-style threaded reducer bushing for Schedule 80 PVC piping systems using standard MIPT and FIPT threaded connections at 4-inch and 3-inch nominal pipe sizes.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the line completely before removing any existing fittings or threading this bushing into place. Use PTFE thread tape or an approved pipe thread sealant on all threaded connections to ensure a leak-free joint. Do not over-torque threaded PVC fittings, as excessive force can crack the fitting body.
