High-quality flange gasket consisting of 2 oil paper gaskets and a spacer made of temperature-resistant plastic, suitable for the 15 mm intake manifold of your Puch Velux X30 moped / moped with Z50 engine.
The seal also fits Sachs 502, 50/2 and 503 engines. The inner diameter of the inlet gasket is compatible with original 503 cylinders with a seal, as well as with racing cylinders with a 15 mm inlet diameter.
The 4 mm special gasket with round inlet prevents excessive heating of the intake tract, which could have a negative effect on the air-fuel mixture. Excessively high temperatures in the intake tract can reduce the air density and thus reduce the efficiency of the combustion process.
The intake gasket can also be used if the carburettor needs to be raised.
You can find the matching intake manifold and carburetor in the accessories section.
Exclusive product for the highest demands of the quality brand swiing®.
