Change – Heat Exchanger Gasket

Change Heat Exchanger Gasket


When Flexitallic invented the spiral wound gasket in 1912, there was nothing like it. Now, 100 years of innovation later, the company has launched the Change™ gasket.

Robust and resilient, the metal wound heat exchanger gasket is designed to deliver the most dynamic seal ever.

The Change gasket is manufactured with proprietary equipment, using a five-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.

In addition, it is proven to perform without fail at least 60% longer than any other heat exchanger gasket, including the spiral wound, double jacketed, corrugated or kammprofile.
