2.25 - 3.12 CLAMP

It uses a stainless steel band and a stack of Belleville spring washers to maintain consistent clamping force even when connections expand and contract from heat. Commonly used on turbocharger boots, intercooler hoses, and exhaust joints where a standard worm-gear clamp would loosen over time. Replacing a worn or stretched clamp with this constant-torque design helps prevent boost leaks and exhaust leaks under the demanding thermal cycles of a diesel engine.
