OA Profile Compact PTFE Piston Cap Seals
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.
Standard Materials
Cap: 0102 Pigment filled PTFE
Energizer: 70A Nitrile
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 OA profile.
Availability: Inch: 0.281" to 16" rod diameter
