Mastercool 92709-YF-8 — ZEROL HD 46 R1234yf Mobile Air Conditioning Compressor Lubricant

ZEROL HD46 is a fully formulated ISO VG46 grade polyalkylene glycol lubricant designed specifically for application with HFO refrigerant R1234yf in mobile air conditioning (MAC) systems. The product is a double end-capped PAG, and is manufactured to exacting standards of high double endcapping efficiency. ZEROL HD46 is suitable for use in both belt and electrically driven compressors utilising R1234yf, and is also fully suitable for use in R134a belt-driven and electric MAC compressors. 8 fl oz (236ml) bottle.

Key Features

• Optimised Miscibility in HFO Refrigerant R1234yf: Designed specifically for R1234yf systems
• Superior Lubricity: Compared to alternative lubricant types, including standard 'single end-capped' PAG products, and di-capped PAGs with lower di-capped material content
• Exceptional Viscosity Index (VI): The high VI enhances compressor life by ensuring efficient running at temperature extremes. The high VI may also allow the user to select a lower viscosity fluid than typically used, with associated power usage savings
• Good High Temperature and Chemical Stability: Even in presence of water, resulting in system lifetime extension and reduced maintenance costs
• Low Hygroscopicity: Tendency to absorb moisture compared to alternative PAG products with lower di-capping content
• Formulating Expertise: ZEROL HD46 series contain optimised additive technology to provide additional corrosion protection within the A/C system, to further enhance the extreme pressure and anti-wear performance of the PAG, and to maximise fluid lifetime by ensuring against thermal or oxidative deterioration of the lubricant/oils
• Excellent Electrical Resistivity Properties: For electrically driven systems
• Double End-Capped PAG: 85% minimum capping efficiency
• Suitable for Belt and Electric Compressors: Both R1234yf and R134a systems

About R1234yf

R1234yf is the new environmentally-friendly refrigerant standard (GWP less than 1 compared to R-134a GWP of 1,430) mandated for all new vehicles in Europe from January 1, 2017. Classified as a mildly flammable (A2L) refrigerant, it requires specific lubricants for optimal performance and system protection.

Benefits

• Essential for Modern Vehicles: Required for servicing R1234yf systems
• Convenient Size: 8 fl oz (236ml) ideal for individual vehicle service
• Superior Lubrication: Better than standard single end-capped PAG products
• Extended Compressor Life: Exceptional VI ensures efficient operation at temperature extremes
• Power Savings: High VI may allow lower viscosity selection with reduced power usage
• System Protection: Good high temperature and chemical stability extends system lifetime
• Reduced Maintenance: Low hygroscopicity and optimised additives reduce maintenance costs
• Corrosion Protection: Optimised additive technology provides additional protection
• Enhanced Performance: Extreme pressure and anti-wear properties
• Maximised Fluid Lifetime: Protection against thermal or oxidative deterioration
• Dual Compatibility: Suitable for both R1234yf and R134a systems
• Professional Quality: Manufactured to exacting standards

Perfect For

• Automotive A/C service centres
• Mobile A/C specialists
• Individual vehicle service
• Dealership service departments
• Independent garages
• Hybrid and electric vehicle service
• Professional automotive technicians

Why Double End-Capped PAG?

Double end-capped PAG lubricants offer significant advantages over standard single end-capped products:

• Superior Lubricity: Better lubrication properties
• Lower Hygroscopicity: Absorbs less moisture from atmosphere
• Better Stability: More stable in presence of water
• Longer Service Life: Extended fluid lifetime
• 85% Minimum Capping Efficiency: High-quality manufacturing standard

Viscosity Index (VI) Advantages

The exceptional Viscosity Index of ZEROL HD46 provides:

• Temperature Stability: Maintains viscosity across temperature extremes
• Enhanced Compressor Life: Efficient lubrication in all conditions
• Potential Power Savings: May allow lower viscosity selection
• Improved Efficiency: Better performance in hot and cold conditions

Optimised Additive Technology

ZEROL HD46 contains carefully formulated additives to:

• Provide Corrosion Protection: Additional protection for A/C system components
• Enhance Extreme Pressure Performance: Better protection under high loads
• Improve Anti-Wear Properties: Reduced component wear
• Maximise Fluid Lifetime: Protection against thermal and oxidative deterioration

How to Use

1. Verify vehicle requires R1234yf or R134a (check service label)
2. Determine correct oil quantity for system (consult manufacturer specifications)
3. Use clean, dedicated oil injector for R1234yf systems
4. Measure exact oil quantity required
5. Add oil through appropriate service port (typically low-side)
6. If replacing compressor, add oil per new compressor instructions
7. Record oil quantity added on service documentation

Storage and Handling

• Store in cool, dry location
• Keep container tightly sealed when not in use
• Protect from moisture contamination
• Use within expiry date
• Do not mix with other oil types
• Use dedicated equipment for R1234yf to prevent cross-contamination

Safety Guidelines

• Wear safety glasses when handling
• Ensure adequate ventilation
• Follow proper refrigerant handling procedures
• R1234yf is mildly flammable - no smoking, sparks, or open flames
• Use dedicated equipment - don't cross-contaminate with R134a tools
• Follow manufacturer specifications for oil quantities
