Twinlip NBR medium to heavy duty rod wiper.

- Design -

Claron Style PWE double acting Rod wiper is designed to remove potential system contaminants from a reciprocating rod during the negative stroke and to assist sealing by collecting the fluid film on the positive 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 wipers ability to assist sealing make it ideal for use where zero leakage is required. Claron Wiper Seals Style PWE should not be utilised in combination with double-acting Rod seals unless the housing design allows for pressure relief between the wiper and the seal.
