Metalflex Styles - 911, 911M, 911T, 914 - Teadit - #1

Teadit Metalflex® 911 Spiral-wound gaskets are made of a preformed metallic strip and a soft filler material (PTFE or graphite), wound together under pressure. The metal strip holds the filler, resulting in excellent mechanical resistance, resilience and recovery.

This spiral wound is constructed with a metallic winding and a filler element. The winding is manufactured from metal in a complicated form of a spiral, in assembly with a filler material. The metallic Winding, of special profile, provides excellent resistance, compensating the changes in operational conditions such as: variations of pressure and temperature, vibrations, thermal shocks, etc. The filler materials fill the irregularities of the flanges.

For applications with high temperature variations (thermal cycling), and/or pressure variations, and/or flange rotation problems etc., gaskets with adequate residual stress (stress retention), flexibility and recovery are needed. TEADIT spiral-wound gaskets have been designed to meet these demanding requirements. The flanges should be designed to provide compression limitation to the gasket's optimum compressed thickness (Please contact Teadit Technical Department for details).
