FAQ
Compression set indicates the permanent deformation of an O-ring after compression and release, affecting its ability to maintain a seal. A high compression set suggests material fatigue and reduced sealing effectiveness, which can lead to leaks. However, compression set alone does not directly determine an O-ring’s lifespan.
Key Factors Influencing O-Ring Lifespan:
- Environmental Conditions: Elevated temperatures and chemical exposure can accelerate material degradation, increasing compression set and reducing lifespan.
- Material Properties: Different rubber materials (e.g., Nitrile, EPDM, FKM, Silicone, etc.) have varying resistance to compression set and aging factors such as ozone, UV light, oils, chemicals etc..
- Operational Factors: The level of compression and whether the O-ring is in a static or dynamic application impact its performance. Excessive compression or dynamic movement can lead to a higher compression set.
- Design and Installation: Proper sizing and correct installation are crucial. Incorrect installation or poorly designed glands can cause excessive compression, leading to higher compression set.
To estimate an O-ring’s lifespan, compression set should be evaluated alongside environmental conditions, material properties, and operational factors. Accelerated aging tests and real-world performance data provide insights into how compression set affects lifespan. Regular monitoring and inspection of O-rings in service help predict and extend their useful life, ensuring reliable sealing performance. This holistic assessment allows for more accurate lifespan predictions and proactive maintenance strategies.
