The sealing ring of the distribution box is the best protection, and it plays a very important role in the protection of the waterproof distribution box. Over a long period of time, the continuity of the degree of protection depends on the characteristics of the seal ring. Fix the sealing ring in the correct position. EPDM material has the best protection against most widely used chemicals because of its excellent chemical corrosion resistance. However, the chemical corrosion resistance of the sealing ring varies greatly according to its material, so it is the most effective method to make the chemical composition react directly with the sealing ring according to the needs.
