Design:
Claron Style EGS rod seal is a 2 piece assembly consisting of a Nitrile Rubber sealing element complete with rubberised fabric reinforcement which is backed up by a tough Thermoplastic elastomer header. The complete assembly forms a robust sealing unit for use in high pressure applications where shock loads and pressure spikes are present. This seal is widely used in telescopic cylinder applications.

These range perameters are Maximum simultaneous conditions. Optimum service conditions are affected by temperature,

speed, pressure, surface finish and extrusion gaps. Refer to Appendix 1 for further information.

Housing:

For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machining tolerances refer to the catalogue page of selected seal. Refer to Appendix 4 for value of tolerance symbols.

Fitting:

Style EGS is designed to be fitted into a split gland as shown in the illustration below. The seal can be supplied split to ease fitting if required. For the seal to function correctly, it is important that care be taken in fitting the seal within its housing. For a detailed checklist, refer to Appendix 3.
