MACGREGOR – NASENRING – COMPRESSOR SPARE

The MacGregor Nasenring (Scraper / Lapped Piston Ring with Nose Profile) is a high-precision marine air compressor spare component engineered to provide advanced pressure sealing and effective oil control within compressor cylinder liners. Precision-machined with a stepped, “nosed” outer profile from wear-resistant, high-grade alloy cast iron, this specialized ring acts as a dual-function compression and scraping element—stripping excess lubricant from the cylinder wall while preventing high-pressure gas blow-by. Built to withstand extreme thermal stresses, mechanical friction, and continuous engine room vibration, it minimizes oil carry-over into downstream compressed air systems and reduces carbon deposit formation on valve assemblies. Tailored for exact fitment across MacGregor marine air compressor lines, it maintains peak volumetric efficiency, optimizes oil consumption, and ensures reliable long-term performance for commercial shipping vessels, cargo equipment, and offshore installations.
