The OLD CASTLE V-2644 is a molded PVC DWV adapter sleeve designed to transition between spigot and hub connections in drain, waste, and vent piping systems. Built to SDR 35 standards, this P Series fitting accepts a 4-inch spigot on one end and a 4-inch hub on the other, joining sections of DWV piping with a solvent weld bond. The fitting measures 4.77 inches in diameter and 1.89 inches in length. Licensed plumbers and pipefitters install this fitting during new construction, remodel, and underground drainage work where a reliable spigot-to-hub transition is required.
This adapter sleeve is suited for residential and commercial DWV applications using 4-inch PVC pipe. It is commonly installed in horizontal drain runs, vertical stacks, and below-grade sewer laterals where SDR 35 PVC is the specified pipe material. The solvent weld connection method creates a permanent, watertight joint appropriate for gravity-flow drainage systems operating under typical DWV service conditions.
Designed as an OEM-style replacement and standard fitting for 4-inch SDR 35 PVC DWV piping systems in residential and commercial drain, waste, and vent applications.
Installation should be performed by a licensed plumber in accordance with applicable plumbing codes, including the International Plumbing Code (IPC) where adopted. Shut off water service and verify the line is depressurized and drained before cutting into an existing DWV system. Apply an approved PVC primer and solvent cement rated for DWV service to both the spigot and hub surfaces before joining. Allow full cure time per the solvent cement manufacturer instructions before restoring flow.
