Technical Data

FAQ

Is the MVQ O-ring suitable for dynamic applications?
Primarily designed for static sealing. In high-speed dynamic systems, materials such as NBR or FKM may be more appropriate depending on pressure and friction conditions.

Can silicone O-rings be used in outdoor and UV-exposed environments?
Yes. MVQ provides outstanding ozone, UV, and weather resistance, making it ideal for outdoor machinery and environmental exposure.

Is this O-ring safe for food and medical applications?
Due to its clean properties and resistance to aging and odor transfer, silicone is commonly used in hygienic sectors, depending on certification requirements.

What does the hardness 70 ShA indicate?
It defines material stiffness and compression behavior, ensuring optimal sealing performance without excessive deformation.
