Copperfit 1A1584 Abs Dwv Cap 4 Inch Slip

Product Description

The COPPERFIT 1A1584 is a 4-inch slip-fit cap for ABS drain, waste, and vent (DWV) piping systems. It terminates an open pipe end, preventing flow, debris entry, and odor escape in residential and light commercial drain and vent lines. The slip connection fits directly over the outside diameter of a standard 4-inch ABS pipe and is solvent-welded in place. Plumbers and pipefitters install this fitting during new construction, remodel work, and system testing when a permanent or temporary pipe termination is needed. At 0.44 pounds, it is lightweight and easy to handle in confined spaces such as crawl spaces and wall cavities.

This cap is suited for residential and light commercial DWV applications where ABS pipe is the system material of choice. Common uses include capping stub-outs during rough-in inspections, permanently closing unused branch lines, and terminating vent stacks at the roof or within a wall assembly. It is installed by licensed plumbers or qualified pipefitters working under applicable plumbing codes.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or locally adopted plumbing codes. Before installing, confirm the pipe end is clean, dry, and free of burrs or debris. Apply a compatible ABS solvent-weld cement to both the pipe exterior and the fitting socket, then seat the cap fully and hold briefly for initial set. Do not pressure-test the joint until the cement has fully cured per the cement manufacturer's instructions.
