Claron Polyseal Single Acting Rod Wiper Seal PWK

Design:

Claron Style PWK 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 92° shore Polyurethane. The wiper is machine trimmed to provide a precise wiping lip. The design incorporates ribs on the heel working face to ensure concentricity and stability.

Operating Conditions:

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