Reliable Sealing Is Essential in Water Treatment. Water and wastewater treatment facilities operate in challenging environments defined by harsh chemicals, strict regulations, and continuous service demands. A failed gasket can result in unplanned downtime, safety risks, or compliance issues. Selecting the right sealing material—such as Durlon® 7910, available from Capital Rubber & Gasket—plays a critical role in maintaining system integrity.
Sealing Challenges in Water and Wastewater Facilities
Treatment facilities must manage fluctuating pressures, exposure to aggressive media like chlorinated water and sludge, and adherence to NSF/ANSI 61 standards. Seal failures are often traced back to materials that cannot withstand these demanding conditions over time.
