Rod Seal CR Profile

Rod Seal CR Profile

Rod Seal CR Profile


Description

The Parker CR profile is a cap seal with anti-extrusion, low friction and low wear features. The seal is a bi-directional rod seal for use in pneumatic and low to medium duty applications. Because of its short assembly length, it requires minimal space in the rod housing. The three CR profiles will fit into standard O-ring grooves without modification. Parker’s CR profiles will retrofit non-Parker seals of similar design.
  • CR0 fits a standard O-ring groove
  • CR1 fits an O-ring groove designed for one back-up ring
  • CR2 fits an O-ring groove designed for two back-up rings
The CR profile may be ordered without the energizer by omitting the energizer code. See part number nomenclature in the downloadable PDF.

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