S.T. Dupont Replacement Lighter Valve Clapper

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

Installed within the lighter’s gas valve system, the clapper acts as a moving sealing component that helps control the release of fuel. Replacing a worn or damaged clapper can help restore correct gas regulation and reduce problems associated with leakage or inconsistent lighter operation.

This precision component is intended for professional lighter servicing. Compatibility may vary according to the lighter model and production period, so the existing component and reference number should be carefully checked before installation.
