Additional to the machined seals Stepseal® 2K and Rimseal for housings ISO 7425/2 (rubber energized plastic seals) the U-Cup RU6 has been developed as an injection molded seal of polyurethane material to fit in the same ISO housings. The integrated NBR O-Ring (only available for series RU62 - RU64) improves the performance at low pressure and low temperature applications. Polyurethane (Zurcon® Z20) is a proven material for U-cups due to their good mechanical properties.
