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 EBR – Rod Buffer Ring

EBR Rod Buffer Rings are linear, uni-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 geometry will provide controlled sealability during stroke extension while preventing pressure trapping and allowing fluid return during stroke retraction. The EBR profile will retrofit non-Eclipse seals designed for similar hardware.

Typical Range of Application

Pressure	Temperature*	Velocity	Media
1,500 – 5,000 psi [100 – 350 bar]	-30°F to 250°F [-34°C to 121°C]	13 fps [4 m/s]	Hydraulic/Mineral Oil or similar

*Limited by O-Ring compound
				Values and ratings in this catalog are based on industry standard applications operating under ideal conditions. The customer should assume responsiblity for validation testing of performance and suitabilty of Eclipse Engineering products. Eclipse Engineering accepts no liabilty for the accuracy and applicabilty of provided information.
