Reducer Bushing 4" x 2" PVC Schedule 40 - Spigot x FIPT (438-420)

Reducer bushing designed to adapt a 4" spigot connection down to a 2" female threaded connection. Molded from durable Schedule 40 PVC, this fitting provides a secure transition between larger spigot pipe and smaller threaded fittings commonly used in irrigation, pool, and general plumbing systems. Part number 438-420 is a compact, easy-to-install solution for contractors and DIYers who need a reliable size reduction in PVC piping runs.

• Material: Injection-molded Schedule 40 PVC for corrosion resistance and long service life.
• Connection: 4" spigot (male) to 2" female threaded (FIPT) — designed to mate with standard threaded and spigot pipe sizes.
• Typical uses: Irrigation, pool & spa plumbing, sprinkler systems, and other non-pressurized or low-pressure PVC applications where a size reducer is required.
• Installation: Solvent-weld the spigot end into Schedule 40 socket or hub; thread the FIPT side into the receiving fitting. Follow solvent cement manufacturer cure times before pressurizing.
• Compatibility: Fits standard Schedule 40 PVC piping and common threaded plumbing fittings; check fitting orientation and thread type before assembly.

This reducer bushing offers a simple, space-saving way to reduce from 4" to 2" without complex adapters. For best results, clean and prime joint surfaces, use the correct PVC primer and solvent cement for Schedule 40 PVC, and verify local plumbing codes for use in potable water or pressurized systems. If you need assistance confirming compatibility with your system, consult a licensed plumber or our product support resources.
