Copper spring gasket

A flat gasket relies solely on compression for sealing, while a spring gasket incorporates wave-form geometry that provides additional axial spring force. This maintains constant pressure on the joint even if bolts relax due to thermal expansion or vibration, making spring gaskets superior for dynamic or high-cycle applications.

Wave height should be approximately 15-30% of the total gasket thickness. For high-torque applications with smooth flanges, lower wave heights (0.2-0.5mm) provide adequate spring action. For rough or uneven flanges, taller waves (0.8-2.0mm) compensate for surface irregularities. We recommend engineering analysis based on your bolt torque and flange finish.

Yes — the spring action maintains constant bolt preload even under continuous vibration, preventing joint loosening. For extreme vibration, multi-wave configurations (6+ waves) provide more uniform force distribution and improved damping characteristics compared to standard flat washers.

All parameters are customizable: inner diameter, outer diameter, thickness, wave height, number of waves, wave pattern (sinusoidal, conical, multi-wave), material alloy (C11000, C12200, C10100), surface finish (annealed, half-hard, tinned, silver plated), and even non-circular shapes for unique flange designs.
