What O-ring groove? - our customers askThe depth of the groove should be adapted to the specific purpose - this will make the seal impermeable. The ratio of the seal cross-section diameter (s) to the groove depth determines the preload. If you are looking for a static seal, the initial stress should be between 15 and 30%. However, in the case of dynamic use, the best solution will be to choose a larger groove depth, and hence a smaller initial stress (usually from 6 to 20%).
When determining the width of the groove, consider:
- O-ring diameter (s)
- oval form formed after assembly
- free space, which is necessary to ensure even pressure
It is important to prevent the groove from overfilling - the O-ring should fill it to a maximum of 85%, leaving room for possible increase in volume.
The table gives the groove parameters for static use (depth and width):
