Piston Seal OE Profile

Piston Seal OE Profile


The Parker OE profile is a bi-directional piston seal for use in low to medium duty hydraulic applications. The OE profile is a two piece design comprised of a standard size Parker O-ring energizing a wear resistant PTFE cap. The OE profile offers long wear, 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 will retrofit non-Parker seals of similar design.

The OE profile may be ordered without the energizer by omitting the energizer code. See part number nomenclature in the downloadable PDF.

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 your local Zatkoff Seals & Packings representative for the availability and cost to add side notches to the OE profile.
