Anatomy of a Flexis
Stainless tube. Protected outside.
The flexible element is corrugated 316L stainless steel with a protective polyethylene (PE) outer layer. The end connectors contain EPDM seals; the flexible element is not a rubber hose.
- 316L corrugated tube. Stainless steel forms the flexible waterway.
- Protective PE outer layer. Polyethylene surrounds the steel tube, outside the waterway.
- End connections. Chrome-plated brass fittings contain EPDM seals. Select the correct connection and model approval scope.
- Vibration isolation. Reduces noise transfer and pipe-movement stress at the connection.
- Built to last. 100+ year design life, subject to the specified installation and operating conditions. Ask for the applicable warranty terms.
