End Seals

Advance Products & Systems End Seals outperform the costly and labor-intensive brick and mortar method of sealing casing ends.

While soil stress and pipe movement cause mortar to crack, the APS products move with the pipe, ensuring the integrity of the seal. And, unlike link-type sealing blocks that are limited to carrier/casing differential and can only be used on a concentric profile, the APS seals are totally flexible. APS offers four types of end seals that can accommodate any combination of pipe sizes.

Models for Every Application

The models AC and AM are seamless and can easily be pulled on at the time of construction while the model AW wrap-around is designed to facilitate installation when the carrier line has already been welded together and the pull is complete. Simply wrap around the carrier and casing, remove the release liner from the two pressure sensitive butyl mastic strips and press the adhesive strips down to form a seal.

Model AZ, zipper type end seal, wraps around the casing end and carrier pipe and zips shut to provide a tight seal while still allowing for pipe movement. All four are made of 1/8″ thick synthetic rubber assuring excellent chemical resistance and resiliency and are secured with stainless steel banding straps with a 100% non-magnetic worm gear mechanism to insure the integrity of the clamp. Only a screwdriver is required for installation.

In addition, Innerlynx form a mechanical seal between pipelines and casing. Innerlynx form a hydrostatic seal and electrically insulate the carrier pipe from the casing. Innerlynx can be installed by one person and require no special tools.
