ESS Scraper Seals are linear, double-acting, seal and rod wipers typically used in reciprocating hydraulic cylinder assemblies but available for a wide variety of industries and applications. Advantages include long wear life, low friction, and simple groove design. The geometry will provide controlled sealability during stroke extension while wiping outside contamination during stroke retraction. The ESS profile will retrofit non-Eclipse seals designed for similar hardware.
