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.
