The new compression step moulding vulcanization process guarantees good physical and chemical properties, a homogeneous surface quality and consistent tolerances over the whole circumference of the O-ring comparable to those of an O-ring manufactured in a mould.

– No limits to the internal diameter
– Tolerances comparable to those of a standard O-ring according to ISO 3601-1 and ISO 3601-3 (grade N and S)
– Chemical and physical properties equal to those of a standard O-ring
– Large variety of materials, also with conformities (such as FDA)
– No tooling costs
– Low costs
– Short delivery times, express service possible
