When we invented the spiral wound gasket in 1912 there was nothing like it. 100 years of innovation later, we introduce the Change gasket. And again there’s nothing like it.

Change™ has become the most significant development in the gasket and sealing industry in the past five years with more than 50,000 sold into sectors such as Steel, Power, Chemical, Refining, and Pulp and Paper, around the world.

Developed by Flexitallic in direct response to customers’ long-term heat exchanger sealing problems, Change™ is a highly-resilient metal-wound gasket, designed to deliver the most dynamic static sealing technology ever.

Manufactured using proprietary equipment, Change™ has a proven track-record showing it outperforms conventional gasket technology in challenging environments, especially in applications with mechanical and thermal cycling conditions. 

It has also achieved independent industry accreditation from TA Luft for its ability to deliver the tightness of a Kammprofile with the recovery of a Spiral Wound Gasket.

This is achieved through the application of a unique metal spiral profile, which is more advanced than those found in standard gaskets. This profile, combined with a laser welding process, facilitates the construction of a robust and dynamic seal
