Material Selection is Important
Sealing materials for drinking water systems must meet food-grade standards and must not release harmful substances. Commonly used materials include food-grade silicone, EPDM rubber, and FKM fluoroelastomer, each of which is suitable for different temperatures, pressures, and chemical environments. Choosing the wrong sealing material can lead to material degradation, water contamination or seal failure, resulting in serious product liability issues.
