BUNA-N (Nitrile) vs Natural rubber

[Nukie]

I'd like to get the pro and cons about BUNA-N (Nitrile) and Natural rubber for use as a gasket material on water and air.

Albion is recommanding natural black rubber for water (hot & cold) and also for air.
Albion also do ot recommand Nitrile for sunlight,ozone and weather...

My applications are inside of buildings with water or air.
And the purpose of my request is to eliminate our inventory of black natural rubber to avoid misuses of it as a gasket on systems with petroleum products.

I know that it can create problems if nitrile is used outside but it is not a concern for us.

Thanks
