Change™ Heat Exchanger Gasket

Flexitallic: Change™ Heat Exchanger Gasket

The Change gasket is manufactured with proprietary equipment, using a 5-times thicker metal spiral and a unique laser welding process that penetrates completely through the winding, so it requires no inner or outer ring and is easy to handle and install as a double-jacketed gasket.

Best of all, it’s proven to perform without fail at least 60% longer than any other heat exchanger gasket – spiral wound, double jacketed, corrugated or kammprofile.
