Seal Ring Piston - Eclipse Engineering

ESR Piston seals are linear, bi-directional, elastomer energized seals 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 ESR profile will retrofit non-Eclipse seals designed for similar hardware.
