Deesawala Rubber Industries stands as one of the best manufacturers and suppliers of premium quality PTFE & Teflon Cladded Dam Gate Rubber Seals. Our Dam Gate Rubber Seals are highly regarded for their fine quality. Dams and barrages are constructed to store or redirect water for irrigation or generation of electric power. In concrete dams, tunnels, spillways, and other water structures, hydraulic gates help manage the water flow. We use seals on either side of the gate or the metal frame in the gate slot to stop water from flowing past a closed gate. Rubber is a popular choice which is used material for seals, as it is elastic, deforms readily and goes back to its original shape on removal of load.
