The biggest reason of O-ring failure is compression set. An effective O-ring seal requires a continuous “seal line” between the sealed surfaces. The establishment of this “seal line” is a function of gland design and seal cross-section which determines the correct amount of squeeze (compression) on the O-ring to maintain seal integrity without excessive deformation of the seal element.
The following suggestions may improve the rate of compression set:
1. Use “Low Compression Set” O-ring material whenever possible.
2. Select O-ring material compatible for the intended service conditions (a material with higher temperature capability or greater chemical resistance).
3. Reduce the system operating temperature.
4. Check frictional heat build-up at seal interface and reduce if excessive.
5. Verify groove dimensions are consistent with recommended Parker practices
