Mercedes Air Compressor Piston Ring Set 2.0mm (2.0/2.0/2.5/4.0), W112/W109/W100 - Fits Knorr Compressors Types

This is a set of 4 piston rings with 2.0mm compression rings (rings number 1 and 2). There are two different top compression rings used in the compressor pistons: 2.0 mm and 2.5mm. 2.5mm is more common but there are versions with 2.0mm

The 2.5mm (ring number 3) and 4.0 mm (ring number 4)   rings are the same in all compressors and used in both Piston Ring Sets offered. 

Please check your old ring dimensions carefully before ordering.
