Fuel-Resistant Fluorosilicone Gasket Sheet

Fuel-resistant fluorosilicone rubber sheet for cutting gaskets, seals and interface components exposed to volatile fuels, oils, solvents and selected chemicals. It combines the flexibility and temperature stability associated with silicone rubber with improved resistance to aggressive fluids that can degrade general-purpose silicone.

Technical specification

Typical applications

• Fuel-system and oil-service gasket prototypes
• Seals for equipment exposed to selected solvents or chemicals
• High- and low-temperature fluid-sealing trials
• Automotive, aerospace and industrial component evaluation
• Small custom gaskets, washers and interface pads

Selecting a thickness

Select the thickness to suit the joint clearance, surface flatness and required compression. The 0.8 mm grade suits low-profile joints and detailed cutting; 1.6 mm provides a practical intermediate section; 3.2 mm offers more material for wider gaps and less-uniform mating surfaces. Check that the finished joint compresses evenly without crushing or extruding the gasket.

Cutting and installation

1. Measure the mating faces and mark the gasket outline, fixing holes and fluid apertures.
2. Cut with a sharp knife, punch, die or suitable gasket-cutting equipment on a stable surface.
3. Remove burrs, residue and contamination from the mating faces.
4. Fit without twisting or stretching, then tighten fixings progressively to distribute pressure.
5. Inspect for leaks and retest after the first thermal or pressure cycle where the application requires it.

Compatibility and design limitations

Fluorosilicone is selected where ordinary silicone may be unsuitable for contact with fuels, oils and aggressive fluids, but compatibility is not universal. Performance depends on the exact chemical or fuel formulation, concentration, exposure time, temperature, pressure and gasket geometry.

Confirm compatibility with the actual service fluid and validate the finished assembly before production use. The stated −53°C to +260°C material range does not mean every fluid, pressure or sealing arrangement is suitable across that full range. No aviation, medical, food-contact or other regulatory approval is implied.

Supplied: one 200 × 200 mm sheet in the selected thickness. Finished gaskets, cutting tools and workbench accessories shown in illustrative imagery are not included.
