Nitrogen Aviation Grade

An inert gas with low oxygen and moisture levels.


Nitrogen, unlike air, does not permeate easily through rubber or seals found in aircraft components. It is also inert and therefore ideal to inflate aircraft tyre to prevent oxidative degradation of the rubber, with the added advantage of its inert nature preventing fire due to brake heat transfer. Nitrogen is used in oil-filled shock absorbers to optimise damping efficiency and to prevent oil 'dieseling' during compression. Due to its non-explosive properties, nitrogen is used to inflate life rafts. Nitrogen is also used to inert aircraft fuel tanks to reduce the risk of combustion.
