DanaCover Rod Seal VR

DanaCover is designed for static applications where o-ring or o-ring with back-up ring is insufficient.
DanaCover is machined out of high-quality hydrolysis resistant polyurethane so any dimension available.

Thanks to the production method we can square fine tolerances and by that optimal performance. Further the performance is reinforced trough the seal-design and low compression-set of the material.

The performance of the seal will always depend on the overall picture of the working conditions.

Verification can only be done by testing the seal in the actual working conditions.
