WIPER -- 40 X 48 X 5/7 -- 6586600

The 33 type wiper has a lip designed to remove lightly adhered dirt from the rod i.e. mud, dust or moisture. The wiper is manufactured from a hard nitrile rubber suitable for installing in a grooved housing. Rod diameters of 20mm and below require a two piece housing. To prevent dirt passing the outside of the wiper and to reduce the pumping action, the outside diameter is an interference fit with the housing. Certain sizes of the standard 33 metric range are suitable for ISO6195 Housing Type A.
