It is built to hold constant sealing tension on truck coolant, charge-air and exhaust connections, clamping a \u003cstrong\u003e3.50-3.81in\u003c\/strong\u003e range with a \u003cstrong\u003e300 series stainless steel band\u003c\/strong\u003e. A clamp that has relaxed lets coolant weep down the block, lets a charge-air boot walk off its pipe under boost, and turns a soot-stained exhaust joint into a shop visit. Manufactured by Automann to Fleet Standard specifications, this clamp is stocked heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eConstant Tension: The Spring-Loaded T-Bolt Advantage\u003c\/h2\u003e\n\n\u003cp\u003eAn ordinary worm-gear clamp is a fixed diameter. Hoses and boots swell when they get hot and shrink back when they cool, and after enough heat cycles that fixed clamp is simply no longer tight. The \u003cstrong\u003espring-loaded T-Bolt design\u003c\/strong\u003e answers that with spring tension behind the bolt: as the joint expands and contracts, the spring takes up the slack and the band keeps pulling. That is the whole point of this clamp, and it is why it \u003cstrong\u003emaintains clamping force through the heat cycles where worm-gear clamps loosen\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe band itself is \u003cstrong\u003e0.031in thick 300 series stainless steel\u003c\/strong\u003e and \u003cstrong\u003e0.75in wide\u003c\/strong\u003e, so it spreads load across the hose instead of cutting a groove into it, which matters on soft silicone charge-air cooler boots. The \u003cstrong\u003e1\/4in-28 plated bolt\u003c\/strong\u003e gives a proper torque handle and resists seizing in road salt.
