Model W Wrap-Around End Seal by GPT

Black EPDM 60 end seals to be used on each of the casing. Suitable for temperatures up to 250°F.


PSI Model "W" Wrap Around Casing 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.

Model "W" Wrap Around End Seals are designed to accommodate customer supplied specifications so they may be used for any size casing/carrier differential. Manufactured from 1/8" thick specially compounded synthetic rubber, PSI Model "W" end seals are extremely robust, resistant to wide variations in environmental conditions while eliminating the possibility of foreign material entering the opening between carrier and casing pipes.

Included with Model "W" End Seals are two appropriately sized hose clamps, which are used to secure the rubber material around both carrier and casing pipes. Installation is quick and easy, with only a screwdriver needed for tightening the hose clamps.
