The VALUE COLLECTION 438-421 is a Schedule 40 PVC pipe bushing designed to reduce a 4-inch pipe connection down to a 2.5-inch fitting. It features a Slip (spigot) inlet and a Female Iron Pipe Thread (FIPT) outlet, allowing a smooth-bore pipe end to be inserted into the bushing while the threaded end connects to a standard threaded female fitting. This bushing is commonly installed by plumbers and pipefitters in drain, waste, vent, and low-pressure water distribution systems. At 1.05 pounds, it is a straightforward reducer fitting appropriate for both new construction and retrofit applications.
This bushing is suited for residential and light commercial plumbing installations where a 4-inch main line or hub must be reduced to a 2.5-inch threaded branch connection. Typical applications include drain line transitions, irrigation manifold assemblies, and industrial process piping where Schedule 40 PVC is the specified material. The FIPT outlet accepts a standard male-threaded fitting or pipe end, making it compatible with a wide range of PVC and CPVC threaded components in low-pressure systems.
Designed as an OEM-style replacement or new-installation fitting for Schedule 40 PVC piping systems using 4-inch to 2.5-inch reducing bushing configurations.
Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Shut off the water supply and depressurize the line before cutting into any existing piping. The Slip inlet requires proper PVC primer and solvent cement applied per the cement manufacturer instructions before assembly. Do not use this fitting on systems operating above the pressure or temperature limits published for Schedule 40 PVC.
