1. Preventing Installation Damage
Tip: Use dedicated O-Ring installation tools (e.g., plastic tweezers, lead-in sleeves) and avoid sharp tools. Ensure all threads, holes, and sharp edges are covered or deburred.
Our Solution: We offer high tear-strength materials (e.g., certain polyurethanes) that better withstand stretching and nicking during installation.
2. Preventing Extrusion
Tip: Extrusion occurs with excessive clearance or high pressure. Match system pressure to the hardness (e.g., 70 Shore A, 90 Shore A) of your O-Ring. Using Back-up Rings is crucial in high-pressure applications.
Our Solution: We provide compounds in various hardnesses and dedicated high-pressure sealing solutions, including matching back-up rings.
3. Minimizing Compression Set
Tip: Compression set (loss of elasticity) is often caused by high temperatures or incorrect material choice. For high-temp applications, choose materials like FKM (Fluorocarbon) or FFKM (Perfluoroelastomer).
Our Solution: We use premium polymers and optimized curing processes to produce O-Rings with a low compression set, ensuring they stay elastic even at elevated temperatures.
4. Resisting Chemical Attack
Tip: There is no "universal" material. Always consult a Chemical Compatibility Chart for the specific fluid you are sealing. E.g., EPDM resists steam but not oil, while NBR resists oil but not ozone.
Our Solution: We offer a wide range of materials from NBR and FKM to specialty compounds, and provide expert technical support to help you select the most compatible material for your media.
Conclusion:
Proper selection, installation, and maintenance are key to sealing success. If you have questions about the best O-Ring for your specific application, our engineering team is here to help.
