50High pressure rotary lip seals
High Pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. high pressure hydraulic seals is made with slip ring and o-ring/square ring.
It adopts a toothed section, which is easier to install. The two grooves are the same and interchangeable. They are used to seal the rod, shaft, pin and rotary joint with high-speed rotation or swing movement. They have the characteristics of high pressure resistance, wear resistance, high temperature resistance, resistance to most chemicals.
