Sealing Ring FAQ
Q: What factors should I consider when selecting a sealing ring?
A: When choosing a sealing ring, consider these critical factors: the media being sealed (chemical compatibility), operating temperature range, pressure requirements, dynamic vs. static application, and environmental conditions. Our technical team can help you select the optimal sealing ring material and design for your specific application.
Q: How do I determine the correct size of sealing ring needed for my application?
A: Proper sizing requires measuring three key dimensions: inner diameter, outer diameter, and cross-section thickness. For dynamic applications, we recommend considering the groove design according to ISO 3601 standards. Our catalog provides detailed dimensional tables, or you can send us your specifications for custom sealing ring solutions.
Q: What maintenance is required for sealing rings in long-term applications?
A: Sealing rings generally require minimal maintenance, but periodic inspection is recommended. Check for signs of wear, hardening, cracking, or extrusion. In dynamic applications, consider lubrication if not pre-lubricated. Storage conditions also affect sealing ring lifespan - keep them in cool, dark places away from ozone sources.
