Frequently Asked Questions (FAQ):

Q1: Is this O-ring suitable for dynamic applications?
A1: While primarily designed for static sealing, NBR O-rings can be used in slow-moving dynamic applications. For high-speed dynamic applications, consider materials like FKM or HNBR.​

Q2: Can this O-ring withstand exposure to sunlight or outdoor conditions?
A2: NBR has limited resistance to UV radiation and ozone. For outdoor applications, EPDM O-rings are recommended due to their superior weather resistance.​

Q3: What is the maximum pressure this O-ring can handle?
A3: The pressure tolerance depends on the application and gland design. Generally, NBR O-rings with 70 Shore A hardness are suitable for pressures up to 80 bars in static applications.​

Q4: Are these O-rings compliant with food-grade standards?
A4: Standard NBR O-rings are not food-grade compliant. For food and beverage applications, consider using FDA-approved materials like silicone or EPDM.​
