The EM rod seal/wiper ring for pneumatic applications is a proven combination element for sealing piston rods in compact pneumatic cylinders and valve lifters. The special design using a wear-resistant Ultrathan® compound enables installation in smallest grooves for extremely low break-away and dynamic friction.

• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Bi-functional element: seal and wiper.
• Extreme wear resistance.
• Low static and dynamic friction thanks to miniaturized design.
• Smooth running due to optimum adjustment of the functional lips.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Excellent media resistance in case of suitable compound selection.
• Short axial assembly length.
• Short radial assembly depth.
• Installation in closed and undercut housings.
• Low compression set.
• The coordinated geometries of the seal and wiper lips achieve favorable friction coefficients and long service life.
