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.
