The IPEX 40424 is a 4-inch PVC cleanout plug with male pipe thread (MPT) connection, manufactured to SDR35 dimensional standards. This plug is designed to seal cleanout access points in gravity-flow drainage and sewer piping systems. It threads directly into a female cleanout fitting, providing a removable, pressure-resistant closure that allows future access for rodding or inspection. Plumbers install this fitting during new construction rough-in and during service calls on existing drain-waste-vent systems. The PVC construction resists corrosion, root intrusion, and common household and commercial drain chemicals.
This cleanout plug is suited for residential and light commercial drain, waste, and vent (DWV) piping systems. It is compatible with SDR35 PVC sewer and drain piping conforming to ASTM D2729 and ASTM D3034 specifications. Typical install locations include sewer laterals, building drain cleanout risers, and underground DWV runs where periodic access may be required for maintenance or inspection.
Designed as an OEM-style replacement and new-installation fitting for SDR35 PVC drain and sewer systems conforming to ASTM D2729 and ASTM D3034.
Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and applicable local codes. Thread the plug into the female cleanout opening by hand first, then tighten with a pipe wrench or strap wrench to achieve a leak-free seal. Apply thread sealant tape or compound rated for PVC and drain service before threading. Always verify that the system is depressurized and flow is stopped before removing or installing a cleanout plug in an active line.
