Safety Warning

Item Information

The A2 wiper seal / ring serves to prevent ingress of dust, dirt, sand and swarf into dynamic rod guides. This is achieved by its special shape, which largely prevents scoring, protects the guidance parts and extends the service life of the seals. The wiper seal has been specifically developed for pneumatic equipment operated with dry and oil-free compressed air. Initial pre-assembly lubrication is a prequisite for impeccable performance. An oversized outer diameter ensures interference fit in the groove and thus prevents intrusion of foreign particles and moisture on the wiper’s outer diameter.


• Good wear resistance.

• Smooth running due to optimum lubricant-retaining sealing lip geometry.

• High temperature resistance in case of suitable compound selection.

• Excellent media resistance in case of suitable compound selection.

• Product geometry prevents dirt deposits at the front face of the cylinder.

• Installation in closed and undercut housings.


Range of application:

Suitable for axially operated rods in pneumatic working cylinders, plungers and rod guides.


The A2 wiper seal is available in the following compounds:

N3587 - Industrial applications

V3664 - High temperatures

N8613 - Low temperatures

P5008 - Heavy-duty
