Why Electropolishing Matters in the Racing World
Murray Corporation manufactures a comprehensive line of constant tension clamps designed to maintain consistent clamping force as hoses and connections expand and contract due to temperature changes, pressure fluctuations, and material relaxation. Constant tension technology is essential for applications where a static clamp would gradually lose its grip, leading to leaks and connection failures.
All hose materials expand when heated and contract when cooled. In applications subject to thermal cycling — such as automotive cooling systems, industrial process lines, and HVAC equipment — a standard clamp that was properly tightened at installation can become loose as the hose diameter changes with temperature. Over time, this gradual loss of clamping force leads to drips, leaks, and eventual connection failure.
Constant tension clamps solve this problem by incorporating a spring element into the clamp design. As the hose expands, the spring allows the clamp to grow with it. As the hose contracts, the spring draws the band back to maintain consistent pressure. This dynamic response keeps the seal tight through repeated thermal cycles without requiring manual retightening.
Murray Corporation offers several constant tension clamp series to address different application requirements. Our Turbo Seal constant tension clamps combine a worm drive adjustment with an integrated spring for easy installation and reliable constant tension performance. The Dual Bead Shield constant tension clamps feature a dual-bead design that provides additional protection against band edge cuts on softer hose materials. The Stack Drive SLHD and SLF series clamps integrate a stacking spring mechanism with a worm drive screw for precise initial adjustment and reliable long-term constant tension.
Each series is available in a range of sizes and materials to meet the requirements of automotive, heavy-duty truck, industrial, marine, and HVAC applications.
Constant tension clamps are critical in any application where thermal cycling or hose relaxation could compromise seal integrity. Common uses include automotive coolant systems, heater hoses, and turbo connections, heavy-duty truck and off-highway vehicle engine systems, industrial process lines subject to temperature variation, marine engine cooling systems, and HVAC chilled water and refrigerant connections.
