This high-quality cooling water hose made of polyethylene (PE) with an integrated steel spiral is specially designed for engine cooling systems in boats. The robust steel spiral construction allows for an exceptionally small bending radius while maintaining high pressure and temperature resistance.
The hose is designed for extreme temperatures from -40°C to +120°C and offers a working pressure of 5 bar (75 psi). The steel spiral prevents collapse under negative pressure and ensures reliable coolant flow under all operating conditions.
