Flexitallic Spiral Wound & Metallic Gaskets
Sutton Clark distributes Flexitallic gaskets and high quality, high value industrial static sealing products throughout the United States.
Developer of the spiral wound gasket in 1912 in the US, Flexitallic today continues its legacy of innovation with gasket product materials like Thermiculite® and Sigma®.
Sutton-Clark, in partnership with Flexitallic’s global customer service network of owned manufacturing facilities and manufacturing licensees ensures demand is met quickly, with a combination of the highest product quality and customer service. Sutton-Clark is a valued member of that network.
Rubber gasket materials are best used in custom gaskets applications generally requiring greater compressibility. Some can withstand temperature extremes up to 500º F and substantial pressure ranges while having a high malleability co-efficient.

About the Flexitallic Material
In 1998 Flexitallic set a new standard for sealing technology with the introduction of Thermiculite Critical Service gasket material available in tanged sheet form. Thermiculite is now available as filler material for spiral wound gaskets and as a facing on kammprofile gaskets. This material has solved numerous end user problem applications, particularly those applications with high temperature processes where traditional sealing materials failed. Thermiculite Critical Service materials are rated for temperatures up to 1600º F and have passed the API 607 fire test.
