I had a conversation with one of our garage managers today about clamps. He told me that our company's fleet (75 reefer rigs, mostly Kenworths without sleepers, with thermokings on the trailers and another dozen long haul rigs have been using these on nearly all of the engine and thermoking hose connections for a little more then the last 5 years without a failure or any "winter weep". I never saw these before. Have you?
