Protective effect on seals
1. Prevent assembly pressure deviation. The sealing rings have limited slots, effectively preventing installation deviation and leakage.
2. UV protection. Cover the periphery of the sealing ring to avoid direct sunlight and increase the service life of the sealing ring.
3. Prevent rainwater. The sealing ring does not directly contact rainwater, reducing corrosion of the sealing ring and increasing its service life.
4. Windproof sand. The sealing ring does not directly come into contact with wind and sand, reducing damage to the sealing ring and increasing the product’s coverage area.
5. Prevent ozone. The high-pressure sealing ring is fully protected and kept away from ozone generation areas to prevent ozone aging of the sealing ring.
