PMW

Single lip metal cased AU medium to heavy duty Press fit rod wiper.

- Design -


Claron Style PMW metal cased Rod wiper is designed to remove potential system contaminents from a reciprocating rod during the negative stroke. It is classified as a medium to heavy duty rod wiper/scraper. The wiper is precision moulded in 98o Shore Polyurethane with an accurately machined lip. The high modulus (stiffness) of this material allows the wiper to scrape tenatious mud and dirt from the rod. The wiper has a metal case designed to press fit in the housing thus retaining the wiper. The metal case is coated with a corrosion resistant yellow Zinc plating. The press fit design of this wiper allows it to be used in simple 'open ended' housing.
