O-ring 66,04x5,33 FPM80 brown

The 66.04×5.33 mm O-ring in FPM (FKM) with a hardness of 80 Shore A is a seal with a classic toroidal profile – circular in cross-section. The profile is made as a single seamless elastomer ring, injection moulded, and the injection point is placed as standard at an angle of 45° to the plane of the cross-section, which minimises the effect of the injection mark on the sealing function. The toroidal geometry ensures line contact with the surfaces of the sealing groove on both the pressure side and the atmospheric side. The FPM material (fluoroelastomer, also referred to as FKM or Viton®) is characterised by very good chemical resistance to mineral oils, hydrocarbon fuels, mineral-based hydraulic fluids, greases and most acids and aromatic solvents. A hardness of 80 Shore A means a higher degree of hardness compared with the typical standard of 70 Shore A, which results in a reduced tendency for the material to extrude at higher operating pressures. The seal meets the requirements of DIN 3771 and can be used in static (axial and radial) and dynamic (reciprocating) sealing applications in hydraulic and pneumatic equipment, industrial valves, engines and gearboxes.
