Exhaust manifold stub o-ring type - BGM PRO - Ø=37mm, Vespa PX80, PX125, PX150, TS, Sprint, Sprint Veloce, GT, GTR, Super, GL, VNA, VNB, VBA, VBB - weld on type, incl. o-ring

Exhaust flange for welding. Suitable for many common exhaust systems. The O-ring provides a good seal against leaking Öl and fuel Üsse. No more Ölnasen running down the Krümmer. The regular diameter of the PX125 exhaust ports is 37mm. Some manufacturers of tuning cylinders take it here with the tolerance is not too accurate, so we recommend the fit on the respective cylinder used to check before mounting. The included O-ring made of the material FPM is resistant up to 240°C, against Öle and fuels. When processing the exhaust flange, the O-ring should not be fitted, as significantly higher temperatures can occur on the workpiece during welding. If the exhaust is used without clamping on the connecting piece, the exhaust manifold should be attached to the engine with springs. For this purpose, we also offer suitable sets with retaining plates for welding to the manifold and for bolting to the engine under Accessories.
