1630204005 OEM Oil 5L L Piston Fluid For Atlas Copco

L Piston Fluid (1630204005) is a synthetic compressor oil, supplied in a 1.3 US gallon (5 liter) can and formulated for piston air compressors. As the lubricant that circulates through the pump, it protects the compressor's moving parts while resisting the high temperatures and oxidation that break down ordinary oils. Its low pour point of -49 °F (-45 °C) keeps the oil flowing for dependable starts in cold conditions, and it is engineered for excellent seal compatibility so gaskets and seals stay in good condition over the life of the fill.

Being a synthetic grade, it carries a service interval of 3,000 hours or two years, which helps optimize maintenance planning and reduce downtime between oil changes. It has a viscosity of 47.28 mm²/s at 104 °F (40 °C) and a viscosity index of 109, giving stable protection across the operating temperature range. Check your compressor's recommended oil grade and crankcase capacity before ordering, since that tells you how many cans a complete change will take.
