Design:
Claron Style PSR retainer is designed to retain single acting piston seals. The retainer is manufactured from Acetal (POM) and is profiled to fit into a groove on the piston. The retainer is split with two holes similar to a circlip to facilitate fitting with circlip pliers. The retainer provides a simple housing design solution for all single acting piston seals.

Housing:
For surface finish and recommended lead in chamfers refer to the illustration below. For seal housing dimensions and machining tolerances refer to the catalogue page of selected seal. Refer to Appendix 4 for value of tolerance symbols.
Fitting:
Style PSR snap fits into a groove and may be fitted with standard circlip pliers. 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.
