The A1 wiper seal / ring serves to prevent ingress of dust, dirt, sand and swarf. This is achieved by its special design which largely prevents scoring, protects the guiding parts and extends the service life of the seals. 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.
