HYDRAUNYCOIL FH 14

Product catalog summary

Description: Hydraunycoil FH 14 is a petroleum-based hydraulic fluid with a viscosity of 40 cSt at 40°C and a viscosity index over 280. It offers excellent anti-rust and anti-wear properties, is micro-filtered, and has controlled particulate contamination. It operates effectively in temperatures ranging from -40°C to +135°C in air-tight circuits.

Applications: This fluid is primarily used as an operational preservative for ordnance equipment, including recoil systems and hydraulic systems for rotating weapon or aiming devices. It is specifically designed for the Krauss-Maffei Leopard tank and hydraulic fluid for bridge ledger, balancing viscosity, low-temperature performance, anti-wear, and corrosion protection.

NYCO HYDRAUNYCOIL FH 14 TECHNICAL DATA SHEET ANTI-CORROSION & ANTI-WEAR PETROLEUM HYDRAULIC FLUID NATO CODE H-540 TL 9150-0035 ISSUE 7 VJS PHM 6-5-p| Hydraunycoil FH 14 is a petroleum-based hydraulic fluid with a viscosity of 40 cSt at 40°C and a viscosity index exceeding 280. It exhibits good anti-rust as well as antiwear properties. Hydraunycoil FH 14 is micro-filtered and is supplied with a controlled particulate contamination. It can be used over an extremely wide temperature range, from -40°C to + 135°C in air-tight circuits. HYDRAUNYCOIL FH 14 is intended primarily for use as an operational preservative fluid for ordnance equipment such as recoil systems and hydraulic systems for rotating weapon or aiming devices. It has been particularly designed for the Krauss-Maffei Leopard tank and as hydraulic fluid for bridge ledger where it offers the right balance of viscosity, low temperature viscosity, anti-wear and corrosion protection.
