Why Electropolishing Matters in the Racing World
Murray Corporation manufactures the SLHD and SLF series Stack Drive constant tension worm drive clamps, engineered to deliver precise initial adjustment and reliable long-term constant tension in a compact, easy-to-install package. The Stack Drive design integrates a proprietary stacking spring mechanism with a worm drive screw, providing both the adjustability of a worm drive clamp and the self-compensating constant tension performance needed for thermally cycling applications.
The SLHD and SLF series clamps use Murray's Stack Drive spring design, which stacks multiple spring elements to create a controlled, progressive constant tension response. As the hose expands and contracts with temperature changes, the stacked springs extend and compress to keep the band at the correct tension. This multi-spring approach delivers more consistent force across a wider range of diameter change than single-spring designs.
The SLHD series features a 5/8-inch band width for applications requiring broader load distribution, while the SLF series uses a 9/16-inch band width for applications where a slightly narrower profile is preferred. Both series provide the same Stack Drive constant tension technology and are manufactured from stainless steel.
Murray's Stack Drive clamps combine worm drive adjustability with stacking spring constant tension technology. The multi-spring design provides consistent force across a wide compensation range. Available in two band widths to match application requirements, the stainless steel construction resists corrosion. Installation uses standard tools with no specialized equipment required. And the compact profile fits in tight spaces.
Stack Drive SLHD and SLF series clamps are used in applications where thermal cycling and hose relaxation demand constant tension performance, including automotive cooling systems and heater hose connections, heavy-duty truck and off-highway engine cooling, turbocharger and intercooler silicone hose connections, marine engine and cooling system hoses, and industrial process lines with temperature variation.
