Fernco EPDM End Caps 37mm to 115mm

Fernco EPDM End Caps blank off the open end of a soil, waste or drain pipe with a rubber cap and a stainless steel clamp band, no glue needed. Fernco is the new name for Flexseal, and their caps are sized by the outside diameter of the pipe in millimetres, so each size covers a range rather than one nominal size.

Use one to seal a redundant branch after a sink, bath or toilet comes out, to close a drain while a job is part done, or to blank a pipe for an air or water test. Fernco make the caps for any pipe material, above or below ground, and the cap comes off again by slackening the band.

Which size do I need?

Measure across the outside of the pipe and pick the size whose range takes that figure. As a guide, 40mm plastic waste (about 43mm across) takes the 37mm to 45mm cap, 50mm plastic waste (about 56mm) the 48mm to 56mm cap, 82mm plastic soil the 76mm to 85mm cap and 110mm plastic soil or drain the 105mm to 115mm cap. Old cast iron and clay vary, so measure them, or bring the measurement to the counter.

Fitting tips

Cut the pipe square and clean it so the rubber seals on a smooth surface. Push the cap fully home and tighten the band to 6Nm. Fernco rate the clamp to 0.6 bar, so brace the cap when the pipe is under test, especially on smooth plastic pipe where a cap can slide. Couplings, elbows and tees are in our flexible rubber connectors range.

Common Questions

Can a Fernco end cap be used on cast iron or clay? Yes. Fernco make them for any pipe material. Measure the outside of the old pipe, because cast iron and clay sizes vary.

Can I use one for a drain test? Yes, Fernco make them for air and water testing of drains. The clamp seals up to 0.6 bar, and the cap should be braced while the test is on.

Can I take the cap off later? Yes. Slacken the band and pull it off, then use it again.
