The Parker ON profile is a bi-directional rod seal for use in low to medium duty hydraulic actuators. The ON profile is a simple two piece design comprised of a standard size Parker O-ring energizing a wear resistant PTFE cap. The ON profile offers long wear and low friction, and because of its short assembly length, requires minimal space in the rod housing. The seal is commonly used in applications such as mobile hydraulics, machine tools, injection molding machines and hydraulic presses. Parker's ON profile is designed to retrofit non-Parker seals of similar design. Options: Notched side walls: Notches can be added to the side walls of the PTFE cap. This can help to optimize the seal's response to fluid pressure. Notched side walls help ensure that fluid pressure fills the cavity between the side face of the seal and the side face of the seal gland. Consult EPS Division for the availability and cost to add side notches to the ON profile.
