The SealOn Advantage

Extreme Resistance

Demonstrates outstanding resistance to harsh chemicals and extreme temperatures, ensuring long-lasting sealing integrity even under aggressive operating conditions.

Superior Sealing Performance

Imparts excellent compression resistance and dimensional stability, maintaining a consistent sealing force over prolonged use to prevent premature failure.

Long-Term Durability

Enables superior mechanical strength with reduced creep and minimal relaxation over time, contributing to the gasket's long-term durability.

The Science Behind the Seal


What truly differentiates GeoWool SealOn is its unique composition. A low Loss on Ignition (LOI) and carefully controlled fibre length distribution greatly influence the gasket's long-term performance, setting it apart from conventional fibres used in sealing compounds.
