The fire connection coupling is an indispensable specialized connection equipment for the fire-fighting water supply system. Provides quick connection of fire hoses, fire trucks, external hydrants and straight stream trunks, forming a continuous water supply line for transporting pressure fire water and mixed fire extinguishing compounds, ensuring reliable connection of pipelines when extinguishing fires. The design is rationally thought out, consists of a coupling body, a seal seat, a rubber seal and a retaining ring, it is easy to disassemble and assemble, has excellent sealing properties.
On the surface of the seal seat there are special channels for fastening the fire hose with a cable, preventing the hose from slipping and leaking at high operating pressure. Built-in high-quality rubber seal completely prevents water leakage from the connection under pressure. High-strength corrosion-resistant and frost-resistant material, easy quick connection, reliable fixation of the connection. Widely used in all internal and external fire-fighting water supply systems, it is a basic key component that ensures the tightness of lines when supplying water and extinguishing fires.
