Key benefits
Why this product
- Generates immense clamping force in ultra-compact axial cavities where standard coil springs cannot fit
- Modular stacking allows plant engineers to infinitely tune spring load and travel by altering washer arrangement
- Maintains constant gasket bolt tension on high-temperature chemical reactor flanges during thermal cycling
- Prevents valve stem packing leaks by providing continuous live-load compensation as packing wears
