Shanghai Leah manufactures a comprehensive range of compressor piston and rider rings for the vast majority of reciprocating compressors, produced in a range of Leah’s Special Polymers and other nonmetallic materials.

Many successful field applications using these unique materials have increasingly transformed both oil free and lubricated compressor reliability resulting in better sealing, less wear and longer life.

Custom designed rings for specific applications have been successfully developed for particularly demanding applications and Leah has completed numerous conversions from lubricated to non-lubricated operation.
