NA SPIRAL WOUND GASKETPTFE
Instead of the conventional asbestos filler, this type uses inorganic fibers and aramid fibers as non-asbestos paper filler.
FEATURES
- Asbestos fibers are not used.
- The service range (heat resistance, pressure resistance) is different from that of the asbestos SWG,but the sealing performance is almost the same.
APPLICATION
Suitable for use in piping flanges, pressure vessels, heat exchangers, valve bonnets,etc.in various industries,especially in locations where asbestos is not allowed.
