Dana X Seal heavy P068
Dana X Seal heavy is the heavy-duty version of the Dana X Seal. The Dana X Seal combines the Dana Glide qualities low friction, long service life and no stick-slip with the static sealing effect of a Quad-Ring® and is particularly suitable for applications where 100% static sealing effect is required for an extended duration. Dana X Seal heavy provides the same features as the Dana X Seal, but with a much enhanced form stability against extrusion. Dana X Seal heavy is typically used in applications where a big metallic clearance is required. To ensure that the profile ring is pressure activated even in conditions with rapid pressure changes, the seal is delivered with notches.
Advantages:
- High dynamic and static sealing effect
- High extrusion resistance
- Low friction

The Rubber-Profile-Rings may limit the temperature range and need to be compatible with the media.
The performance of the seal will always depend on the total picture of working conditions.
Verifying the performance of the seal can only be done by test at the actual working conditions.
