Fernco Quick Caps  

Offer a quick, easy way to cap pipe ends. Made of flexible PVC, they're suitable for above-ground or underground use, on cast iron, steel, copper or plastic piping.

The convex face allows the cap to withstand greater pressure for testing purposes and minimizes ballooning.

To install, simply place over open end of pipe and tighten to 60" lbs. torque. If a Flashback were to get to the cell, this lid will blow off.

The lids are nearly a half inch thick. They can be drilled and tapped for threading an outlet valve for your hose. Under a vacuum, this lid will flex inward. You could minimize that by adding a hard Seal/surface between the end of the pipe and the inside of the cap.

  • Screw the adapter in. No need for threading
  • Lid seals great
  • A back-flash will blow the lid off
  • This picture is of a 4 inch OD ss tube, using a 4 inch Fernco. The cap slid on with ease. The steel band had to be tightened quite a bit to seal the tube.
