Keeping Drinking Water Fresh and Safe — Now and for the Future

Water is life. As climate change and population growth put pressure on global resources, the need for safe, reliable drinking water solutions has never been greater. That’s why Freudenberg Sealing Technologies developed EPDM 335DW—a new O-ring compound designed to meet the world’s toughest standards and help protect public health everywhere.

Why EPDM 335DW?

• Certified for Global Use: EPDM 335DW O-rings have earned all major market approvals, making them the go-to choice for drinking water systems worldwide.
• Engineered for Safety: Rigorously tested for copper compatibility, aging resistance, and extreme temperatures—from hot water and steam up to +150°C, to cold conditions down to -50°C.
• Future-Ready Compliance: The O-rings have been approved according to the latest testing guidelines of KTW-BWGL to already meet the requirements of European legislation (Directive EU 2020/2184) and thus be recognized by independent testing institutions throughout the EU.
• Protecting Health & Environment: Every O-ring is designed to safeguard water quality, conserve resources, and support sustainable infrastructure.
