1-1/2 inch Flexible Cap (Copper Cast Iron PVC or Steel Pipe)

1-1/2" Fernco Qwik Cap – Flexible PVC Cap for Drain, Waste, and Vent Terminations

The 1-1/2" Fernco Qwik Cap is a flexible PVC end cap designed for sealing open pipe ends in non-pressurized DWV systems. It provides a fast, tool-assisted method to cap off cast iron, PVC, ABS, or copper pipes temporarily or permanently. Suitable for use in above-grade and underground applications, this cap complies with plumbing codes requiring mechanical closures on DWV terminations.

Manufactured from elastomeric PVC and equipped with a stainless steel clamp, the Qwik Cap accommodates slight variations in pipe outside diameter. It is typically installed during system testing, maintenance isolation, or where future expansion is anticipated. The reusable design and quick installation make it a reliable component in both new construction and repair work.
