Get a quote

Design:

Claron Style PWS Rod wiper is designed to remove potential system contaminants from a reciprocating rod during the negative stroke. It is classified as a medium to heavy duty wiper and is precision moulded in Nitrile 90o rubber. The wiper is machine trimmed to provide a precise wiping lip.

The addition of sealing beads on this wiper provide positive sealing in the housing preventing moisture/contaminants from passing the outside of the wiper.

Operating conditions:

Optimum service conditions are affected by temperature, speed and surface finish.

Refer to Appendix 1 for further information.
