1-1/4” PVC Trap Adapter – Engineered for Secure Drainage Interfaces

Designed for professional-grade performance, the 1-1/4” PVC Trap Adapter delivers a secure and reliable transition between drain piping and trap assemblies. This adapter is essential in high-demand residential and light commercial drainage systems, where performance and code compliance are non-negotiable.

Built for Durability and Accuracy

Constructed from schedule 40 PVC, this trap adapter maintains structural integrity under standard operating conditions and resists chemical corrosion common in wastewater systems. It accommodates slip-joint installations with precision-machined surfaces for consistent compression and sealing capability.

• ✅ Schedule 40 PVC Body Rated for low-pressure drainage, waste, and vent applications in compliance with ASTM D2665.
• ✅ Slip x Threaded or Slip x Slip Ends Allows flexibility in connection to different fixture tailpieces and trap assemblies.
• ✅ Thermal and Chemical Resistance Maintains dimensional stability in varying conditions common to residential installations.

Common Applications

This fitting is installed in undersink drain systems where it connects tubular trap arms to PVC DWV pipe. It supports configurations in lavatories, kitchen sinks, and utility sinks requiring a stable and code-approved transition fitting.

Installation Guidelines

Use of approved slip-joint nuts and washers is required to maintain watertight performance. Proper deburring and solvent-welding (when applicable) should be executed per IPC and UPC guidelines. Installation must follow local code requirements, particularly regarding vertical and horizontal trap arm alignment and grade.
