Description: SPGA is a double acting seal capable of passing over port.
The Nylon sealing face has a step-cut joint for ease of installation.It composed a rubber energizer.
OK/SPGA double acting piston seal provides the designer with a compact, low friction seal for light to medium duty hydraulic cylinders.
It comprises a PTFE ring, strengthened with additives to resist creep, which is pre-loaded by an O ring to be effective for the operating pressure range recommended. As the pressure rises the O ring deforms and compresses the PTFE ring against the tube wall increasing the sealing force and the effectiveness of the seal. As only the PTFE ring is in contact with the sliding surface, friction is very low and stick-slip movement is eliminated.
The OK/SPGA seal is not recommended for applications where it is necessary for the pressurised cylinder to maintain the load in a set position.
