WHAT IS SEALING ?

Delmon Group is a rubber sealing solutions supplier.

Sealing is an insulation between two parts of a system, this insulation can concern an air or gas passage between two parts with different pressures, a fluid flow, or a fire propagation. Delmon Group develops static and dynamic sealing solutions for major automotive, aeronautical and industrial customers. These technical parts require resistance to external aggressions such as particles, hydrocarbon fluid splashes and extreme temperatures.

As for example the standards : (ISO 2685-1998 and AC20-135).
