Frequently Asked Questions
It acts as the sealing element in a check‑valve, allowing fluid to flow in one direction and preventing reverse flow.
Viton offers superior chemical resistance and durability, making it ideal for high‑cycle, sanitary, and food‑grade systems.
Replace it if you find leaks, degraded sealing, cracking, or any sign that the elastomer is deteriorating.
