Single acting rod seals from the AF-441 series can be used for most hydraulic applications. Different material combinations guarantee high functional security and long life over the entire pressure and velocity range, gives low friction, and takes into account various temperatures and pressure fluids. Special Features: Two part composition comprising of profile slide ring and O-ring Outstanding shear characteristics, no stick- slip effect Good dynamic and static sealing Good abrasion resistance, long life Wide temperature range and chemical re- sistance, depending on O-ring material Designed for mounting in undivided grooves, depending of size Available for all rod diameters up to 2500 mm AF-441 126 Material Operating pressure Velocity Temperature : PTFE-Compound or polyurethane : up to 40 MPa (400 bar) : reciprocating to 15 m/s : -40 to +200 °C Rod Seal
