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.
