The Parker OE profile is a bi-directional piston seal for use in low to medium duty hydraulic actuators. The OE profile is a simple two piece design comprised of a standard size Parker O-ring energizing a wear resistant PTFE cap. The OE profile offers long wear and low friction, and because of its short assembly length, requires minimal gland space on the piston. The seal is commonly used in applications such as mobile hydraulics, machine tools, injection molding machines and hydraulic presses. Parker's OE profile is designed to retrofit non-Parker seals of similar design. Options: Notched side walls: Adding an "N" to the end of the part number indicates that notches are to be added to the side walls of the PTFE cap. Notches can help optimize the seal's response to fluid pressure. In application, the void created by the notch allows fluid pressure to fill the cavity between the side face of the gland and the seal. Consult EPS Division for the availability and cost to add side notches to the OE profile.
