FAQ
What is the difference between silicone clamp rings and EPDM gaskets?
Silicone offers better temperature resistance and flexibility, while EPDM provides superior resistance to steam and certain chemicals. The choice depends on the application environment.
Are silicone clamp rings food-safe?
Yes, most silicone clamp rings are manufactured from FDA-compliant materials and are suitable for food and beverage applications.
Can silicone clamp rings be used in high-pressure systems?
They are generally suitable for low to medium pressure. For high-pressure applications, reinforced or alternative materials may be recommended.
How often should clamp rings be replaced?
Replacement frequency depends on usage conditions, but regular inspection is recommended, especially in hygienic or high-cycle systems.
