ePTFE Spiral Wound Gasket Filler Material
SEALON Filler Material provides excellent gasket mechanical resistance and resilience for spiral wound gasket use
The spiral wound gasket has an outer and inner metal ring which holds in place a thin metal spiral, sandwiched with a non-metallic filler.

ePTFE with its special properties is one of the best filler to take up the flange compression, and compatible with the working fluid and service conditions.

These gaskets are normally used with raised face flanges and give an excellent seal due to the very long leakage path.
