Self-Compensating Screw Drive CTB Clamps eliminate "cold flow" leakage by shutting off the leak paths. These clamps provide the self-adjusting band you need for a dependable seal, even in the coldest conditions. Our standard version offers a lined 9/16" wide stainless steel band with a 5/16" hex-head screw.
