This cup type serves as a sealing component that contains pressurized fluid within a confined chamber. Its plain mechanical function is to maintain a tight seal between two mating surfaces under dynamic conditions. A concrete generic failure consequence is that a cracked or deformed cup may lead to external leakage and gradual loss of system efficiency. The catalog lists the spec as 13X1.
