Design:

 

Claron Style PDS rod seal is a 3 piece assembly consisting of a Nitrile Rubber sealing element which is backed up by a tough Thermoplastic elastomer header complete with an Acetal anti-extrusion ring on the I.D. The complete assembly forms a highly robust sealing unit for use in high pressure applications where shock loads and pressure spikes are present. This seal is widely used in the mobile plant industry and is also a modern replacement for common veepac seals.

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 PDS 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.
