Rubber Vacuum Rings provided by us, are mainly used for various applications. These rings will distort into unequal grooves to some extent if this is not done. To ensure a suitable seal, the orientation of cutting grooves is critical. It's also crucial to have the right groove design. Our provided Rubber Vacuum Rings are very effective and safe to use. Surface roughness, flatness, and surface finish are all important for sealing surfaces. Permeability, modulus to deform into sealing surfaces, and outgassing from the rubber compound are all important considerations in material selection.
