Model "C" Custom Pull-on End Seals are designed to accommodate custom carrier/casing diameter combinations. They are ordered to 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 "C" 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 "C" 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 screw driver needed for tightening the hose clamps.
