18.4-21.6mm Spring Band Clamp - Zinc Plated Steel

Rotor Spring Band Clamps are self-tensioning sealing components, which ensure a leak-free sealing of hose/spigot joints.Utilizing austempered, high-tensile chrome-vanadium spring steel, the final product indicates great flexibility and strength, ensuring a reliable, leak-proof connection of a hose to a fitting.Once the Rotor Hose clamp is installed on the hose joint, there will not be any need to re-torque or re-adjust the clamp over time (compared to a typical screw type clamp).
