Piping Seals

What is an end seal?

An end seal is a 1/8″ thick synthetic rubber seal that eliminates foreign material from entering the annular space between a carrier pipe and a casing pipe. APS offers six types of end seals that can accommodate any combination of pipe sizes.

How do you seal around drain pipes?

Apply caulk or expanding foam around the hole. If the gap around the pipe is wider than an inch, use a solid material like sheet metal, plywood, or rigid foam to fill the hole. Fasten in place with adhesive or short screws and seal with caulk or spray foam.

LINK-SEAL® is a modular, elastomer sealing system that creates a permanent, hydrostatic seal for nearly any cylindrical object as it passes through a barrier.

LINK-SEAL modular seals are considered to be the premier method for permanently sealing pipes of any size passing through walls, floors and ceilings. In fact, any cylindrical object may be quickly, easily and permanently sealed against the entry of water, soil or backfill material. Expansion Joints are often used in the piping system.

For the system approach, metal or non-conductive Century-Line™ sleeves with water stops may be ordered with LINK-SEAL modular seals to ensure correct positioning and a water tight seal of the installation within poured concrete walls.

Pipe Sleeve Seals

Seal pipe sleeves and carrier pipes.

Pipe Seals provide positive, mechanical seals around pipe sleeves and copper or plastic carrier pipes. Often used where rubber expansion joints are used. Industrial Strainers. Temporary Strainers are functional above or below ground to keep out dirt, water, insects and more out of the pipe.

Pipe Seals

For a convenient installation, the carrier pipe slides easily through the Fernco Pipe Sleeve Seal and two stainless steel clamps tighten easily with a screw driver. No need sealing compounds that can typically damage plastic pipes.
