Comma axial seals used for shaft sealing and bore sealing are a further development of the axial C-Seal. The elastic recovery in radial direction is still limited, yet the leakage over the outer diameter in the case of a Comma seal is well controlled by the seating load generated by the compression of the ring part of the design.
Silver, gold or copper plating enhances tightness performance and lowers friction during assembly and operation.
They are typically used in valves, semi-dynamic applications, connectors and in areas that need rod seals and piston seal
