Design:
Claron Style PWM Rod wiper is designed to remove potential system contaminates from a reciprocating rod during the negative stroke. It is classified as a medium duty wiper and is precision moulded in Nitrile 90o rubber.
The wiper is machine trimmed to provide a precise wiping lip.
Operating conditions:
Optimum service conditions are affected by temperature, speed and surface finish.
Refer to Appendix 1section 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 PWM may be deformed and fitted into a closed groove housing as shown below. 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.
