High Demand Item – Frequently Reordered by Contractors
The Fernco Quik Cap is the fast, reusable way to cap a pipe end, pressure-test a DWV line, or seal a cleanout. Made of flexible PVC with a 300-series stainless steel clamp, it slips over the open end of the pipe and tightens down in seconds — no glue, no threads, no waiting.
The convex face resists ballooning under air or water test pressure, and each cap fits a range of pipe materials at its nominal size — plastic, cast iron, copper, steel, stainless, and more. Use it as a temporary test cap or leave it on as a permanent end cap, above ground or buried. Stocked 1-1/2″ through 12″.
Applications
- Pressure-testing DWV, sewer and drain lines (air or water)

FAQ
Is it reusable?
Yes — loosen the clamp and it comes off clean for reuse, or leave it on as a permanent cap.
How do I size it?
Match the cap to your nominal pipe size. Many sizes also fit clay, AC, concrete, or stainless at a nearby size — see the Fits column.
Will it hold test pressure?
Yes — the convex face is designed to resist ballooning during air and water tests. Tighten the clamp to 60 in-lbs.
