            In chemical processing, a simple leak can become a costly, dangerous, or even catastrophic event. From corrosive acids to alkaline solutions and organic solvents, chemical environments push equipment to its limits. Among the critical components exposed to these harsh conditions, seals often bear the brunt of the challenge.
