URA HYDRAULIC FLUID
Description:
URA Hydraulic Fluid is a premium-quality, synthetic, anti-wear, and biodegradable hydraulic fluid developed for industrial and mobile equipment operating in environmentally sensitive areas. Mineral and premium synthetic oils, formulated with synthetic polyol ester (POE) base oils and ashless additives, it ensures excellent lubrication, wear protection, and thermal stability. It is certified as fire-resistant and approved for use in underground mining and fire-prone environments.
Applications:
Mobile and stationary equipment in environmentally sensitive areas.
Hydraulic systems exposed to fire hazards or extreme heat.
Steel mills, foundries, and manufacturing plants.
Underground mining equipment requiring MSHA-approved hydraulic fluids (ISO VG 68, 100).
Industry Approvals:
Factory Mutual Group II, Type HFD-U (ISO 6743-4) – Less Flammable Hydraulic Fluid
MSHA Approved:
Approval No. 35-A080004 (ISO VG 68)
Approval No. 30-20-3 (ISO VG 100)
Key Features & Benefits:
Fire-resistant with high flash point, fire point, and auto-ignition temperature.
Outstanding oxidation resistance and thermal stability.
Excellent wear protection for pumps and motors.
Protects against rust, corrosion, sludge, and varnish formation.
Good low-temperature fluidity and long service life.
Non-toxic, non-irritating, and readily biodegradable.
Certified by Factory Mutual Research Corporation for fire resistance.
Passes US EPA Static Sheen Test (“no sheen” requirement).
Usage Notes:
Should not be mixed with other fluid types.
When converting from other fluids (e.g., water-glycol, phosphate esters), flush the system and verify seal compatibility.
