Jolly JC900 Stainless Steel Constant Tension SAE 912 Hose Clamp 8-1/4" to 9-1/8" Replaces CT900LSS

SKU JC900(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.
