We started Eclipse with the premise that if we could solve enough of our customers problems they would continue to come back to us for solutions regardless of the type of products we offered.

Eclipse has evolved to produce standard product offerings for a wide range of industries including Hydraulics, Pneumatics, Energy Production, Aerospace as well as Pharmaceutical and Food Handling. Instituting ISO9001/AS9100 quality system in 2015 allowed Eclipse to become a top tier supplier.

Today, Eclipse can support our smaller customers that require only a few seals a year to those needing in the 100’s of thousands. We continue to retain a quality product and are able to deliver consistently on time. Our customers continue to bring us challenging projects that allow our team to do what we do best, problem solving.

Eclipse EDS – Piston Channel Seal

EDS Piston 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.

Typical Range of Application

Pressure	Temperature*	Velocity	Media
5,000 psi [350 bar] MAX	-30°F to 250°F [-34°C to 121°C]	16 fps [5 m/s]	Hydraulic Oil, Mineral Oil, Gases

*Limited by O-Ring compound
				Values and ratings in this catalog are based on industry standard applications operating under ideal conditions.
