N-70248 / OD 220 L 190 – PISTON – COMPRESSOR

The N-70248 compressor piston is a heavy-duty marine air compressor replacement piston assembly engineered to deliver precise stroke displacement, optimal compression ratios, and high volumetric air delivery across commercial ship, naval vessel, and offshore compressor systems. Built to rigorous ISO/DIN maritime classification standards, this industrial air compressor piston spare part features high-tensile nodular cast iron or lightweight heat-treated aluminum alloy construction, precision-ground ring groove geometry, and wear-resistant skirt surfaces designed to withstand severe thermal loads, continuous high-pressure piston thrusts, synthetic lubricant exposure, and engine room vibration without scuffing or mechanical distortion. Ideal for routine marine air compressor overhauls, cylinder liner rebuilds, and emergency compression restoration maintenance, the N-70248 OD 220 L 190 piston ensures leak-tight compression, smooth reciprocating balance, minimized operational downtime, and long-term compressor drive reliability.
