O-Cap® type 2555- is a double acting rod seal. It uses the same groove dimensions as ORing +2 Back-Up Ring according to Swedish and Japanese standard. It consists of a Kefloy® ring energized by a rubber O-Ring. The O-Cap® is designed to eliminate the frictional – and wear problems, which may occur with rubber O-Rings.
O-Cap® is pressure responsive. O-Cap® can be used with a great variety of fluids. Kefloy® is compatible with virtually all fluids. O-Cap® is designed to replace rubber O-Rings where they cause frictional – or wear problems. O-Caps® should not be used for new designs.
