Constant Tension Worm Drive Hose Clamps

Cold flow is the failure mode most technicians don't see coming. As a rubber or silicone hose compresses under sustained clamping load, its wall gradually thins — and a fixed-torque clamp, unable to follow that movement, loses sealing force incrementally until a slow leak develops. Tridon's heavy-gauge constant tension worm gear clamps eliminate this through a precision Belleville spring design integrated into the worm gear band — heavier-gauge springs that deliver a higher rate of band tension adjustment than lighter constant tension alternatives, actively compensating for both thermal cycling and progressive cold flow across the full service life of the connection. The included inner liner protects silicone and soft hose surfaces from the shear forces that occur at the band edge under high clamping loads — a critical detail on modern charge air and coolant hose assemblies where hose wall integrity directly affects system pressure retention. Manufactured in stainless steel and available across a wide diameter range, these clamps are the specification choice of heavy-duty commercial engine builders, automotive cooling and charge air system assemblers, and industrial process engineers wherever the cost of an unplanned leak outweighs the cost of specifying correctly in the first place.
