Constant Torque Perforated Worm Drive Hose Clamps (WPC)
The American-type Constant-Torque hose clamp is a heavy-duty stainless steel worm drive hose clamp engineered with a Belleville washer design and an extended inner liner.
The washer design functions as a constant tension spring, allowing for automatic increases or decreases of the clamp diameter in response to variations in operational or environmental temperatures. The extended inner liner is specifically designed to protect all types of hoses from surface damage.
