BMW uses a red colored o-ring to seal the interface between the engine block and the inlet pipe (part #18 in the diagram below) but I'm not sure of the material composition of this oring. For example, it's possible that the o-rings are Viton.
have a metric oring selection kit with many sizes of black Buna-N o-rings. Buna-N is suitable for applications where the temperature range is 0-121 degrees C and has good resistance to petroleum-based oils, greases and hydraulic fluids, water and other common automotive chemicals. Can I use a correctly sized Buna-N o-ring in this application?
