The seal which is manufactured in Kintowe R01, is designed to provide a valve action to prevent excessive pressure build up in the cavity between the buffer seal and the rod seal. A polyacetal/PFC anti-extrusion ring is fitted to provide maximum extrusion resistance against
Manufactured in Kintowe R01, Kintowe K653 is a strong flexibility seal making installation very easy.
Features
*Easy installation
*Long using life
