Quality with a History

1971

Super Seal was founded in 1971 by a GE chemical engineer widely regarded as a leader and innovator in the fields of cross linked polyolefin and electrical resistant compounds. With this strong technical background the company began producing heat shrinkable protective end seals out of its manufacturing plant in Bridgeport, CT.


1985

Due to the company’s success and growth, in 1985 Super Seal moved to a larger and more modern manufacturing facility in Stratford, CT where it continues today as an industry leader in the supply of heat shrinkable end seals serving the wire and cable industries. For over 40 years Super Seal has been providing high quality heat shrink end seals used to environmentally protect and insulate wire, cable, pipe, conduit and roping.
