polyalkylene glycol (PAG) Viscosity 150 HCPRO PAG 150 – Heavy-Duty Reliability for the Toughest Jobs! 

This PAG 150 Oil is a premium-grade AC compressor lubricant formulated for R134a automotive and HVAC systems. Designed with a high-viscosity base, it offers excellent film strength, lubricity, and wear protection, even under high-temperature and high-pressure conditions.

This 8oz bottle is perfect for professional technicians and DIY mechanics servicing air conditioning systems in cars, trucks, and light-duty HVAC units. It is moisture resistant, chemically stable, and compatible with R134a refrigerant.

• ✅ High-viscosity PAG 150 oil designed for R134a AC systems

• ✅ Provides strong lubrication and wear protection under pressure

• ✅ Suitable for automotive compressors and HVAC units

• ✅ Compatible with R134a refrigerant only (not for R1234yf or hybrids)

• ✅ Excellent chemical and thermal stability

• ✅ 8oz bottle – ideal for single system service or top-off

• ✅ Resists moisture absorption to prevent system contamination

• ✅ Not for use with electric or hybrid vehicle compressors

Key Features:

• High Viscosity: Ideal for heavy-duty applications.
• Extreme Load Handling: Protects under high-pressure conditions.
• Thermal Stability: Ensures consistent performance in varying temperatures.
• Lubricity and Anti-Wear: Minimizes friction and extends component life.
• Versatile Use: Suitable for both industrial and automotive systems.

Advantages of PAG Lubricants:

• HIGH VISCOSITY INDEX: Lower viscosity grades than mineral oil-based lubricants can be used for improved efficiency. PAG-based lubricants also don not require viscosity index improvers as mineral oil-based lubricants may.
• LOW VOLATILITY/HIGH FLASH POINT: PAG lubricants have higher flash points and lower volatility than mineral oil-based lubricants. Properly stabilized with antioxidants, flash and fire points of PAG lubricants increase significantly.
• DESIGNED SOLUBILITY: Can be designed to be water-soluble, oil-soluble, or intermediate.
• MINIMAL DEPOSIT FORMATION: Degradation products of PAGs are soluble in PAG lubricant.
• ENVIRONMENTAL ACCEPTABILITY: Many viscosity grades do not harm the environment, have low aquatic toxicity, and are non-bio accumulative.
• HYDROLYTIC STABILITY: PAG lubricants do not break down in the presence of water.
• FIRE-RESISTANT: Combination of lower carbon content than mineral oil, PAOs, or esters; and high flash and fire points.
• WATER TOLERANT: PAG-based lubricants can accommodate higher water content than mineral oil-based lubricants without corrosion.
• THERMAL CONDUCTIVITY: PAG-based lubricants provide better cooling than mineral oil-based lubricants, lowering sump temperatures, and extending equipment and fluid life in some applications.
• LOW FRICTION COEFFICIENTS: Minimal friction generation to minimize wear.
