Produced with a combination of special compound PTFE ring and 70 shore NBR Square-ring, our SPG design has a wide application area. Being able to be usded safely at high linear velocity, SPG type seals can also work in higher temperatures or different liquids by means of changing square-ring used as pressure ring.
