Water and wastewater treatment facilities face aggressive chemicals, regulatory scrutiny, and
demanding operational environments. Gasket failure can lead to costly shutdowns or
noncompliance. That’s why choosing the right sealing material—like Durlon® 7910, available
from Hanna Rubber Company—is critical.
Common Challenges in Wastewater Sealing Applications
Facilities managing water or wastewater deal with fluctuating pressures, aggressive chemical
exposure (chlorinated water, sludge), and strict NSF/ANSI 61 compliance requirements. Sealing
failures often result from subpar materials unable to withstand harsh environments.
