Repair your truck's cooling system with the Stainless Steel Constant Torque Coolant Hose Clamp. This clamp is designed to maintain a consistent, uniform seal across a wide range of hose diameters, making it ideal for coolant, heater, and marine applications. Constructed from high-grade 300-series stainless steel, it features a heavy-gauge Belleville spring design that helps to mitigate leaks and hose cold flow issues, especially in high-heat environments. With dimensions ranging from 2.75 to 3.63 inches, it offers a robust solution for secure hose attachment, and the inner liner protects hose surfaces from damage while resisting corrosion. This clamp is sold individually and comes with a warranty against defects in workmanship and materials. Easy installation is supported, though using a torque wrench is recommended for best results.
