Traditionally, the solution to septic tank inlet and outlet connections has been to leave an oversized hole for pipe insertion. The contractor is then left to fill the remaining void, usually relying on mortar and fill material. The resulting joint is rigid, not watertight, and slows the installation process. A●LOK Septi-Seal Gaskets give your installers a better solution.

The Raider Septi-Seal Gasket is a flexible rubber gasket designed specifically to be cast into a concrete septic tank to accept and seal 4" inlet and outlet pipes. The gasket is cast into the concrete using a special plastic placement ring that positions the gasket so that it is partially locked into the concrete and partially into the void where the pipe goes through.
