Design:

Claron Style PFB double acting Rod wiper is designed to remove potential system contaminents 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 rod wiper. The wiper is precision moulded in 80° Shore Nitrile Rubber with an accurately machined lip. The wiper has a metal case designed to press fit in the housing thus retaining the wiper. The press fit design of this wiper allows it to be used in a simple open ended housing. The sizes are to common Japanese housing standards.Claron Wiper Seals Style PFB 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.
