Jolly JC500 Stainless Steel Constant Tension SAE 512 Hose Clamp 4-1/4" to 5-1/8" Replaces CT500LSS

SKU JC500(001

Jolly Brand's constant tension hose clamps are a superior form of clamps designed to eliminate "cold flow" leaks with their Belleville spring mechanism. This allows the clamp to automatically expand and contract as the engine temperature increases and decreases. They also feature an extended inner liner which protects softer hoses such as silicone from the worm gear serrations. The 5/8" band, housing and screw are made from stainless steel.
