Copperfit 1A1581 Abs Dwv Cap 1.5 Inches Slip

Product Description

The COPPERFIT 1A1581 is a 1.5-inch slip-connect ABS DWV cap used to terminate drain, waste, and vent piping runs. Made from acrylonitrile butadiene styrene (ABS) plastic, this cap presses and solvent-cements onto the spigot end of standard 1.5-inch ABS pipe or fittings to create a sealed, permanent closure. It is a standard component in residential and light commercial DWV systems wherever an open pipe end must be capped off during rough-in, testing, or final installation. Plumbers and pipefitters use this fitting in new construction and remodel work.

This cap is suited for residential and light commercial drain, waste, and vent applications. Common install scenarios include capping stub-outs during rough-in inspections, sealing unused branch openings on tee fittings, and closing off vent piping terminations in walls or ceilings. The slip-style socket end accepts standard 1.5-inch ABS pipe and is joined with ABS solvent cement per applicable plumbing code requirements.

Key Features

• 1.5-inch slip socket end for solvent-cement connection to standard ABS pipe
• ABS construction provides resistance to common drain-line chemicals and moisture
• Lightweight at 0.06 pounds, reducing load on piping assemblies
• Single-piece molded design with no mechanical fasteners or seals to fail
• Suitable for drain, waste, and vent (DWV) service

Compatibility

Designed as an OEM-style replacement and standard fitting for 1.5-inch ABS DWV piping systems in residential and light commercial plumbing installations.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following local plumbing codes and IPC guidelines. Before installation, shut off water supply and ensure the pipe end is clean, dry, and free of burrs. Apply ABS solvent cement to both the pipe spigot and the cap socket, join immediately with a slight twist, and hold for the manufacturer-recommended cure time before pressurizing the system. Do not use this fitting with PVC pipe or PVC solvent cement.
