Gambit AF-300 1 mm Sealing Sheet – 250×750 mm sheet for cutting gaskets
The Gambit AF-300 gasket-cutting sheet (1 mm, 250×750 mm) is a sealing material used by workshops, service centers, and DIY enthusiasts. An asbestos-free aramid sheet (commonly known as Klingerite) with consistent quality from the manufacturer. A flexible sheet that conforms well to uneven flange surfaces. Resistant to brake and coolant fluids—recommended for water and steam systems, as well as automotive applications.
At ADITECH, we cut the 250×750 mm sheet from original Gambit material (manufacturer’s sheet size: 1500×1500 mm). A versatile size for several gaskets at once or a single larger one—e.g., for a manifold, valve cover, or pipe flange. It fits in a workshop drawer.
Why choose the AF-300 sheet?
- Temperature resistance: up to 280°C (continuous operation from -40°C; up to 320°C for short periods; up to 220°C in steam)
- Maximum pressure: 10 MPa
- Resistance to media: water, steam, brake fluids, coolants
- Asbestos-free material—safe to process and install
- Easy to cut: with a utility knife, scissors, die cutter, plotter, or cutting machine

How to cut a gasket from a gasket sheet?
- Trace the shape of the old gasket or flange directly onto the sheet.
- Cut along the outline with a sharp knife, scissors, or a die cutter—for large batches, a plotter is best.
- Drill the screw holes with a punch or hole saw, and gently smooth the edges.
- When installing, tighten the screws evenly, in a crisscross pattern, using the torque recommended for the specific connection.
Frequently Asked Questions
Does the AF-300 panel contain asbestos?
No. Gambit AF-300 is an asbestos-free material that complies with applicable regulations.
What thickness of gasket sheet should I choose?
Thinner sheets (0.3–1 mm) work well on smooth, rigid surfaces, while thicker ones (1.5–4 mm) better fill in unevenness and compensate for flange deformation. The easiest way is to measure your old gasket.
Need a different size or thickness?
We offer additional sizes and thicknesses of this material—and if you can’t find the size you need, write to us, and we’ll check if we can cut it to size.
The specified limit values (temperature, pressure) do not occur simultaneously and are for reference only. The selection of material for a specific application should be verified against the manufacturer’s technical data sheet.
