PSI Model W Wrap-Around End Seals

Model “W” End Seals are designed for existing installations. A plastic backing is simply removed to expose the self-curing rubber on both ends of the end seal. Once the two are pressed together a solid bond is created between mating surfaces and carrier/casing pipes. Model “W” end seals are available for all carrier/casing differentials.

Typical Application

PSI End Seal Model W Typical Application

Installation

  1. Prepare outside surfaces by removing dirt from Casing and carrier pipe.
  2. Wrap end seal around carrier pipe and casing pipe, make sure the widest portion of the end seal gets wrapped around the casing pipe.
  3. Overlap the edges of the end seal with the release papers facing toward each other.
  4. Remove release papers and firmly press together the entire seal area along the edge. Repeat the pressing process to make sure seam is tight.
  5. Position banding clamp approximately 1″ from the end of the casing pipe and then tighten onto the end seal.
  6. Fold end seal in an S shape so it will extend into the casing.
  7. Position banding clamp approximately 1″ from the end of the end seal on the carrier pipe and then tighten. (Make sure the end seal is folded into the casing, to relieve stress during backfilling and allow for expansion and contraction movement.)
  8. Repeat on other end of casing.
