Mishimoto constant-tension worm gear clamp for 2.76–3.62 in (70–92 mm) diameters keeps clamps tight through thermal cycles. The spring on the adjustment bolt maintains continuous pressure in high-temperature applications, reducing the risk of loosening over time. Stainless construction resists corrosion, and the worm gear mechanism provides straightforward tightening for coolant, intake and charge-line use. The clamp is covered by a Mishimoto lifetime warranty.
