MACGREGOR – OIL SCRAPER RING – COMPRESSOR SPARE

The MacGregor Oil Scraper Ring (Oil Control Ring) is a precision-engineered piston ring spare designed to precisely regulate lubrication along the cylinder bore of marine air compressors. Precision-machined from wear-resistant alloy cast iron with specially angled scraping edges, this heavy-duty ring strips excess oil from the cylinder wall during the downward stroke and returns it to the crankcase, leaving only a uniform, thin film for piston lubrication. Manufactured to withstand extreme mechanical friction, high operating temperatures, and continuous engine room vibration, it effectively prevents lubricant carry-over into compressed air lines, reduces carbon buildup on valves, and minimizes overall oil consumption. Tailored for exact compatibility with MacGregor marine air compressor systems, it maintains peak volumetric efficiency and extends maintenance intervals for commercial shipping vessels, cargo handling equipment, and offshore installations.
