TSI Supercool Synthetic PAG A/C Compressor Oil for R134a – 1 Quart with UV Leak Dye, Anti-Wear Protection

TSI Supercool 27897 is a premium synthetic PAG compressor lubricant formulated for R134a aftermarket air conditioning systems and includes UV dye for quick leak detection.

This 1-quart synthetic PAG oil is engineered to help keep aftermarket A/C systems running smoothly by offering strong moisture resistance, enhanced lubricity, and additives that protect moving parts. It meets OEM performance benchmarks and is intended specifically for use with R134a refrigerant in retrofit or replacement systems. The included ultraviolet tracer dye simplifies diagnosis by making leaks visible under UV inspection lights.

How does this oil protect my A/C compressor?

The formulation contains anti-wear agents and conditioners that reduce metal-to-metal contact and help preserve compressor life under normal operating conditions. While no lubricant can prevent all failures, this oil helps lower friction and surface degradation inside the compressor.

• Anti-wear additives reduce component wear
• Conditioners maintain film strength at operating temperatures
• Optimized viscosity for reliable oil circulation

Will it work with my vehicle's aftermarket R134a system?

TSI Supercool 27897 is formulated specifically for aftermarket systems charged with R134a refrigerant. It is not intended for factory-charged vehicles that require different lubricants or for other refrigerants unless the system has been converted to accept R134a and PAG oil.

• Designed for aftermarket R134a applications only
• Not recommended for systems needing mineral oil or POE variants
• Compatible with retrofitted A/C components built for PAG oils

How does the UV dye help with maintenance?

The built-in ultraviolet tracer dye disperses through the A/C circuit so technicians can pinpoint leaks quickly using a UV light. This saves diagnostic time and simplifies locating seals, hoses, or fittings that require repair or replacement.

• Dye makes refrigerant/oil leaks fluoresce under UV inspection
• Speeds up leak detection and repair planning
• Works with standard automotive UV inspection lamps

What performance standards and handling should I know about?

This synthetic PAG oil meets typical OEM performance expectations for aftermarket R134a systems and contains inhibitors to limit moisture uptake. Store in a sealed container, avoid contamination, and follow safety guidance when handling refrigerant systems.

• Formulated to meet OEM-style performance levels for PAG oils
• Resists moisture to help maintain oil and system integrity
• Keep container closed and protect from dirt or water contamination

Who is this for: TSI Supercool 27897 is aimed at professional technicians and DIY enthusiasts who service or retrofit automotive A/C systems using R134a and want a high-performance synthetic PAG lubricant with UV dye for easier leak detection. Choose this product when you need a moisture-resistant, anti-wear oil that aligns with aftermarket R134a requirements and simplifies troubleshooting during maintenance.
