Schedule 40 PVC reducer coupling (model 429-251) provides a straight inline transition from 2" to 1-1/2" pipe using solvent-weld slip ends. Manufactured for durability in Schedule 40 PVC systems, this white injection-molded fitting is widely used in irrigation, pool and spa, and other PVC piping applications that require a reliable, sized down connection.

  • Nominal size: 2" x 1-1/2" (slip x slip)
  • Material: Rigid PVC, injection-molded for consistent dimensions
  • Schedule: SCH 40/STD suitable for standard Schedule 40 PVC pipe
  • Installation: Slip ends for solvent-weld installation using PVC primer and cement
  • Standards: Manufactured to ASTM D2466 and listed to NSF/ANSI piping standards where specified
  • Finish & rating: White color; manufacturer lists a maximum temperature rating near 140°F (follow local codes)

This reducer coupling is designed to create a secure solvent-weld joint between a larger 2" line and a 1-1/2" line without adapters or threaded transitions. Verify pipe schedule and local plumbing codes before use. Handle and store fittings out of direct sunlight until installed; allow the recommended cure time for primer and cement before pressurizing the system.
