The Parker OA profile is a bi-directional piston seal for use in low to medium duty hydraulic actuators. The OA profile is a two piece design utilizing a rectangular PTFE cap and standard size Parker O-ring. The OA profile is an excellent choice for applications requiring a compact design. The unique properties of the modified PTFE provide added wear resistance for improved cycle life. Parker's OA profile is designed to retrofit non-Parker seals of similar design.
