DGS-300 Dam Gate Seal Installed on Hydroelectric Dam
NHPC-Approved Dam Gate Seal - Type DGS-300
Our Type DGS-300 Dam Gate Seal is specifically engineered for hydroelectric dam applications and approved by NHPC (National Hydroelectric Power Corporation). Manufactured from premium EPDM rubber compound, these seals provide exceptional water-tight integrity under high hydrostatic pressure while maintaining flexibility across extreme temperature variations. Each seal undergoes rigorous pressure testing and quality certification to meet stringent dam safety standards.
