The oil scraper rings produced by DONGYI are all made of our factory’s own material formulas such as DY101, DY920 and DY116 and other different materials. By designing different structures, they can be well applied to Z-type compressor, D-type compressor, M-type compressor, W-type compressor, V-type compressor.
Our company’s oil scraper ring assembly can effectively prevent the lubricating oil in the crankcase from leaking along the piston rod.
