33 Wiper Seal

The Hallite 33 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 (d1) 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 diamter is an interference fit with the housing. Certain sizes of the standard Hallite 33 metric range are suitable for ISO6195 Housing Type A.

It should be noted that the Hallite 33 inch profile differs from the metric profile. Many of the metric sizes are also available as polyester wipers – see Hallite 38.
