Channel Seal Rod

EDS Rod Channel Seals are linear, bi-directional, elastomer energized seals typically used in light duty reciprocating assemblies but available for a wide variety of industries and applications. EDS profiles are designed to work in standard O-Ring grooves without modification. Advantages include extrusion resistance, low friction, and compact groove design. The EDS profile will retrofit non-Eclipse seals designed for similar hardware.
