Supa Seal one-piece polyurethane seals are the Manuli Hydraulics answer to the need for superior performance and extended service life in staple lock fitting seals. Moulded to tight tolerances and designed to withstand extreme conditions, the Supa Seal range offers multiple advantages over the traditional O-ring and backup ring arrangement, including an excellent resistance to abrasion, wear and contamination, and easy assembly and maintenance. Supa Seals are colour-coded for easy identification and are insensitive to pressure peaks with an excellent resistance to shock loads.
