Nyco HYDRAUNYCOIL FH2 (5-LTR-CAN)

Additional Product Information

Overview

Hydraunycoil FH 2 is a high-performance synthetic hydraulic fluid formulated from a blend of poly-alpha-olefins and diesters. Engineered for aviation and MRO applications, it provides excellent low-temperature stability, anti-wear and anti-corrosion protection, and fire-resistant properties. Maintenance and engineering teams rely on it for critical aerospace hydraulic systems, landing gear struts, and actuator operations due to its reliability, thermal stability, and broad operating range from -40 C (-40 F) to +205 C (+401 F).
