Accofluor spring activated lip seal ASL-Seals Type ASL-seal is a single-acting, spring activated PTFE seal for both piston and rod. ASL-seals are appropriate for use as a dynamic seal at slowly rotating or reciprocating movements as well as a shaft e.g. an O-ring in seal or static seal. ASL seals often,replace rubber seal applications with high or low low temperatures, non-lubricated services, Type ASL-seals can be delivered with many different spring types and materials adjusted to demands on friction, aggressive media, high The advantages of series ASL-Seals are e.g.: High chemical resistance Withstands speeds up to 15 m/s Wide temperature range, –254°C – +310°C (depending on the choice of material) Withstands pressures up to 40 MPa (standard) Higher pressures demand special design FDA quality Accofluor ASL-Seals are designated according to a system that states the seal series/type, dynamic seal diameter, cross-section and choice of material.
