LASCO 437-420 PVC Reducer Bushing, 4" x 2" Spigot x Slip, Schedule 40

LASCO 437-420 reducer bushing adapts a 4" spigot to a 2" socket in Schedule 40 PVC piping. Injection-molded white PVC provides a lightweight, corrosion-resistant connection commonly used in pool, spa, irrigation and general plumbing systems where Schedule 40 dimensions are required.

• Size & connections: 4" nominal spigot (male) to 2" nominal slip/socket (female) — IPS sizes for Schedule 40 systems.
• Material: Durable injection-molded PVC, white finish resists corrosion and most common chemicals used in pool and irrigation systems.
• Schedule & standards: Manufactured to Schedule 40 dimensions; many listings cite ASTM D2466 and NSF 14/61 compliance for Lasco Schedule 40 fittings.
• Operating range: Suitable for standard Schedule 40 applications — common temperature range up to ~140°F and service pressures typical for this size (see manufacturer data for exact ratings).
• Installation: Intended for solvent-weld (primer and PVC cement) joints on the slip/socket side; spigot end fits into mating socket for a secure connection.
• Applications: Ideal for pool and spa plumbing, irrigation, drainage and non-corrosive liquid handling where Schedule 40 PVC is specified.

Choose the LASCO 437-420 reducer bushing when you need a reliable, easy-to-install transition from 4" to 2" pipe in Schedule 40 systems. Always follow local plumbing codes and the manufacturer’s installation instructions; consult product technical data sheets for precise pressure ratings and any regional restrictions for potable-water use.
