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 for slowly rotating or reciprocating movements as well as a shaft seal or static seal. The series often replaces a rubber seal, e.g. an O-ring in applications with high or low temperatures, vacuum etc. aggressive media,high speeds, high pressures, Type ASL-seals can be delivered with many different spring types and materials adjusted to the application demands and so can the PTFE material. 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.
