MECHANICAL SEAL
This static seal is a development of the traditional radial static structure of O-rings and retaining rings. The strong, symmetrical cross-section structure and the anti-extrusion polyurethane material make the HS easy to install and improve the sealing performance in pressure fluctuation conditions, with a longer service life.
There are two sealing areas, providing double protection and reducing leakage. This structure can reduce the torsion of the seal (whether in assembly or use). The use of anti-extrusion polyurethane material eliminates the need for plastic retaining rings.
