Lasco Reducer Bushing 3" x 1-1/2" Spigot x FPT (438-337)
Lasco 438-337 Reducer Bushing — 3" spigot to 1-1/2" female pipe thread. This Schedule 40 PVC reducing bushing provides a reliable transition from a 3-inch spigot connection to a 1-1/2-inch female pipe thread (FPT). Manufactured to common PVC standards, it is suitable for irrigation, pool plumbing, and many cold-water PVC applications where a threaded connection is required.
- Material: Type I PVC (Schedule 40) for corrosion resistance and long service life.
- Size: 3" spigot x 1-1/2" FPT — MPN/Model 438-337.
- Use: Designed for water, irrigation, and general PVC piping systems (not for compressed air).
- Temperature: Maximum recommended service temperature 140°F; not for hot-water distribution in dwellings.
- Standards: Manufactured to typical SCH 40 PVC specifications (cell classification commonly used in Lasco fittings).
- Installation: Solvent-weld the spigot end into PVC pipe; thread the FPT side to compatible male pipe fittings using appropriate thread sealant or tape.
Choose this reducer bushing when you need a durable, serviceable transition between a larger PVC spigot and a smaller threaded component. Its Schedule 40 wall thickness gives strength for typical above-ground and underground irrigation plumbing. Follow local plumbing codes and manufacturer guidance when installing; avoid use with compressed gases or in systems exceeding the recommended temperature range.
