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 EVSE – Extended Heel Cantilever Spring Energized Rod Seal

In some applications, a combination of pressure, temperature and hardware gap will give rise to a situation where the jacket degrades due to extrusion. A simple upgrade for Cantilever Spring Seals is to increase the length of the seal in order to isolate the spring side of the seal from distortion. By specifying and extended heel version, pressure ratings can be doubled over non-extended designs. This can be useful in cases where rebuilds yield larger than normal extrusion gaps or when legacy designs are pushed to higher operating pressures and temperatures to achieve greater performance. Accumulators and pressure intensifiers are common applications for extended heel Cantilever Spring Seals.
