TSI Supercool PAG 46 A/C Compressor Oil for 1234yf — 8oz Bottle with UV Dye, Anti-Wear Protection

TSI Supercool 27262D is an 8oz synthetic PAG 46 lubricant engineered for automotive A/C systems using 1234yf, formulated with UV dye for straightforward leak detection.

This synthetic polyalkylene glycol (PAG) oil is designed to lubricate and protect A/C compressors that run on the newer 1234yf refrigerant while remaining compatible with R134a systems. Its 46 cSt viscosity gives a balanced film thickness for moving parts, and the added UV dye helps technicians quickly locate refrigerant leaks under blacklight. Combined conditioners, inhibitors and anti-wear agents help maintain reliable performance and moisture resistance in modern HVAC environments.

How does this PAG 46 oil work with 1234yf systems?

TSI Supercool PAG 46 is chemically formulated to mix with 1234yf refrigerant and circulate through the system to reduce friction between compressor components. It forms a protective lubricating film that supports long-term compressor operation without compromising refrigerant function.

• Balanced 46 cSt viscosity for effective lubrication at operating temperatures
• Compatible chemistry for 1234yf refrigerant systems
• Anti-wear agents reduce metal-to-metal contact inside compressors
• Works with R134a applications where PAG oils are specified

Why is UV dye included and how do I use it?

The built-in UV dye makes it easier to pinpoint leaks during diagnostics: a UV lamp reveals dye residues around compromised fittings, hoses or seals. Add the bottle to the system during servicing, then scan suspected leak areas with a UV inspection light for fast visual confirmation.

• Pre-dosed 8oz bottle for convenient service additions
• Visible under UV light to find leaks without disassembly
• Helps reduce diagnostic time and avoid repeated searches
• Safe to use in systems specified for PAG lubrication

What protections and additives are in this lubricant?

The formula incorporates conditioners, inhibitors and anti-wear compounds that bolster moisture resistance and defend moving parts from premature wear. These additives maintain oil performance and help preserve compressor efficiency over time.

• Conditioners keep internal seals and components conditioned
• Inhibitors help prevent corrosion and chemical breakdown
• Anti-wear agents reduce scoring and extend component life
• Enhanced moisture resistance to limit degradation in humid environments

How much should I add and is the packaging user-friendly?

The product ships as a single 8oz bottle—suitable for top-ups, small repairs, or when manufacturers specify this capacity during service. The compact container is easy to store in a service bay or toolbox and is sized for typical A/C system maintenance needs.

• 8oz volume fits common service top-up requirements
• Single-pack convenience for independent technicians or DIYers
• Small footprint for shelf or toolbox storage between jobs
• Clear labeling for quick identification during service

Who is this product for? TSI Supercool 27262D PAG 46 with UV dye is aimed at professional automotive technicians, mobile A/C specialists and informed DIYers working on vehicles retrofitted or originally equipped with 1234yf (and applicable R134a) systems. Choose this bottle when you need a PAG oil that combines appropriate 46 cSt viscosity, UV leak-detection capability and protective additives for routine service or troubleshooting tasks.
