Witryna24 mar 2024 · In general, as the fluid pressure increases, the O-ring is compressed even tighter into the groove, further increasing the contact pressure, and hence helping the O-ring to seal even better. This positive feedback loop of increasing pressure leading to increased sealing is called “self-energizing”. WitrynaO-Ring durometer is measured by the depth of indentation in the material created by a given force using a standardized pressure foot. The indicating scale reads … WitrynaChanging to a softer durometer material can result in up to 50% reduction in the force needed to compress an O-ring.
