Engineered primarily as a long-term rust-inhibiting recoil and hydraulic preservative fluid for military ground equipment, armored vehicles, missile systems, and aerospace hydraulic test rigs, Radcolube FR170 combines a high-flashpoint synthetic polyalphaolefin (PAO) base with advanced rust preventatives, anti-wear agents, and oxidation inhibitors. Designed as a direct fire-resistant alternative to conventional petroleum preservative fluids, FR170 prevents internal system corrosion during prolonged storage and inactive fleet periods while providing exceptional fire safety, shear stability, and hydraulic performance across extreme operating temperatures (-40°C to 204°C).\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications \u0026amp;
