Product Description
High Temperature 70 Shore NBR O-Rings
O-rings are essential sealing components widely used in both dynamic and static applications across various industries. Their popularity stems from low manufacturing costs and ease of installation, making them the preferred choice for high-pressure sealing environments.
International Standards Compliance
Our O-rings meet major international standards including American Standard (AS568), Japanese Standard (JIS B 2401), and International Standard (ISO 3601/1), ensuring global compatibility and reliability.
O-Ring Selection Criteria
Working Medium and Conditions: Material selection begins with compatibility assessment with the working medium. Additional factors include operating pressure, temperature range, continuous working duration, and operational cycles. For rotating applications, frictional heat generation must be carefully evaluated.
Seal Types and Applications:
• Static and dynamic seals by load type
• Piston seals, shaft seals, and rotary shaft seals by purpose
• Radial and axial mounting configurations
For radial shaft seals, maintain minimal deviation between O-ring inside diameter and sealed diameter d2. For piston seals, the inside diameter should equal or slightly undersize the groove diameter d1.
Performance Factors
Material Hardness: The 70 Shore A hardness rating is critical for determining compression characteristics and maximum allowable extrusion gap. This standard nitrile rubber formulation satisfies most industrial requirements.
Extrusion Gap Management: Maximum allowable extrusion gap (Emas) correlates with system pressure, O-ring cross-sectional diameter, and material hardness. Higher working pressures require smaller extrusion gaps to prevent O-ring extrusion and damage.
Compression Set Performance: This key metric evaluates the material's ability to maintain elastic deformation under pressure while resisting permanent plastic deformation.
