Wiper seal Prädifa series A1

The A1 wiper seal / ring serves to prevent ingress of dust, dirt, sand and swarf. An oversized outer diameter ensures interference fit in the groove, thus preventing ingress of foreign particles and moisture via the static seal fit of the wiper.

Product Benefits:

• Good wear resistance.

• High temperature resistance in case of suitable compound selection.

• Excellent media resistance in case of suitable compound selection.

• Suitable compounds available for special requirements of the chemical process industry.

• Suitable compounds available for special requirements of the food processing industry.

• Dimensions according to DIN ISO 6195, Type E.

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

• Installation in closed and undercut housings.

Range of Application:

Axially operated rods in hydraulic and pneumatic working cylinders, plungers and rod guidances.
