Spiral wound steel gaskets are frequently used in environments where pressure and temperature are high. Depending on the working conditions, they are manufactured using different windings (304SS, 316SS, 316L, etc.) and filler materials (PTFE, Pure Graphite, etc.). Depending on the place of use and pressure limits, they are produced in a winding form only (without inner and outer rings), with an inner ring, and with both inner and outer rings.
