The sealing ring made of FPM / FKM (colloquially known as Viton) is temperature-resistant up to 200 °C.
A good replica of the original Austrian version with slightly larger cooling ribs, also known colloquially as the new model, which is cooled by ambient air (airstream).
This head is the best choice for your 45 Athena, DMP, PowerOne, GPO, AKOA, PSR or ParmaKit racing kit (racing cylinder) with large cooling fins. Also ideal for honed Austrian cylinders, of course.
