Constant Tension Worm Drive Hose Clamps

When a hose connection sits on a heavy-duty diesel engine, it doesn't experience one set of conditions — it cycles repeatedly between cold start, operating temperature, peak load, and cooldown, with every cycle working against the fixed sealing force of a standard clamp. Tridon's Constant Tension Worm Gear range is built specifically for this environment, incorporating a self-adjusting spring mechanism that tracks hose diameter changes in real time — tightening as the hose contracts on cooldown and releasing as it expands under heat, maintaining consistent radial pressure without manual intervention at any point in the cycle. The range spans three formats to match different connection profiles: the bead-lined constant tension format for soft and silicone hose assemblies requiring both liner protection and dynamic compensation, the contoured band format for reinforced and non-circular hose profiles, and the heavy-gauge spring format for the most extreme pressure and vibration environments where heavier-gauge spring tension is the only reliable solution. All manufactured in corrosion-resistant stainless steel for long-term performance in the chemically aggressive environments typical of automotive and industrial installations.
