S.T. Dupont Replacement Lighter Valve Flap Assembly

The S.T. Dupont Replacement Valve Flap Assembly is an original service component designed for the maintenance and repair of compatible S.T. Dupont lighter mechanisms.

This internal component forms part of the lighter’s gas valve system, helping regulate the flow of fuel and maintain the correct operation of the mechanism. It is intended to replace a worn or damaged original component during professional servicing.

As compatibility may vary between lighter models and production periods, the existing component and reference number should be checked before installation. Fitting by an experienced lighter technician or authorised service centre is recommended.
