Rubber gate seals are an essential component of rubber gates, specifically designed to seal and prevent the leakage of liquids or gases. Typically installed between the gate leaf and the gate frame, between gate leaves, and between the gate leaf and bottom sill, the seals effectively fill gaps to prevent media from leaking through the gate seams, ensuring the sealing performance of the gate. With its excellent elasticity and deformation capability, the seal can closely fit the contact surfaces of the gate, forming a reliable sealing barrier that allows for precise control of water, gas, and other media when the gate is closed, ensuring the stable operation and safety of the entire system.
