High Demand Item – Frequently Reordered by Contractors
The Fernco QwikSeal is the fast way to tie a service lateral into a sewer or storm main without excavating the whole line. Core a hole in the host pipe or manhole, insert the QwikSeal, push your service pipe through, and tighten the 316 stainless clamp — a watertight connection in minutes, with no glues, epoxies, grout, or hard-to-use hubs.
It seals into concrete, clay, solid-wall plastic, and corrugated host pipe, and handles up to 7° of deflection in concrete manholes. Easy-to-identify colors keep sizing straightforward: green for SDR sewer pipe, grey for PVC Schedule 40 / iron pipe size. Made in the USA and compliant with ASTM C923.

FAQ
What host pipe can it connect to?
Concrete, clay, solid-wall plastic, and corrugated — if you can core a clean hole in it, QwikSeal can seal to it.
What’s the difference between green and grey?
Green QwikSeals fit SDR-35 / SDR-26 sewer pipe; grey QwikSeals (S40) fit PVC Schedule 40 or iron pipe size. Match the color to your service pipe.
Do I need a special hole saw?
Fernco offers matching coring bits — tempered steel hole saws for plastic and diamond-tipped abrasive bits for concrete and clay. Ask us if you need the coring tools.
