Spiral wound gaskets combine the ease of sealing of a graphite, PTFE or mica filler with the strength afforded by a specially profiled metallic, spring-like reinforcement. The sealing element is manufactured by interleaving plies of alternating metallic winding strip and filler to create a gasket that is robust and easy to install.
Spiral wound gaskets can be manufactured from a wide range of metals to resist against chemical attack and temperature related degradation and used in combination with either graphite, PTFE or mica filler.
- Creates a very leak-tight, reliable seal.
- Suitable for high temperatures and pressures.
- Can be manufactured to suit standard flanges and also custom-designed vessels.
Material

Application/Industry
Spiral wound gaskets or semi-metallic gaskets are designed for the widest range of operating conditions of temperature and pressure. They are used in raised face flanges, male and female flanges, and tongue and groove flanges. They are also reliably used in high-temperature and high-pressure applications.
