TSI Supercool PAG 46 Compressor Lubricant for R-1234yf — 8oz Bottle with UV Dye

TSI Supercool 27262D is an 8oz synthetic PAG compressor lubricant formulated for 1234yf A/C systems that includes UV dye for fast leak detection and a 46 cSt viscosity for reliable lubrication.

This synthetic PAG oil is designed specifically for modern vehicle air conditioning that uses 1234yf refrigerant, delivering moisture resistance, anti-wear protection, and additives that help extend compressor life. The built-in UV tracer simplifies locating leaks during service, while the 46 cSt viscosity makes the fluid compatible with many R-1234yf and R-134a applications where this grade is recommended. Packaged in a single 8oz bottle, it’s set up for targeted top-ups and repairs without committing to larger volumes.

How does this lubricant fit into 1234yf A/C maintenance?

Use this PAG 46 oil when the vehicle manufacturer or system service guidelines specify a PAG lubricant of this viscosity for 1234yf systems. It replenishes lubricant lost during component replacement or repairs and helps maintain proper compressor lubrication after refrigerant work. The UV dye also speeds diagnosis of leaks after charging or system pressurization.

• Compatible viscosity: 46 cSt for many 1234yf and some R-134a systems
• Targets top-up and repair jobs with an 8oz bottle
• UV tracer aids post-service leak detection

What protection and additives are included in the formula?

The formula includes conditioners and inhibitors to help fight contaminants and reduce wear on moving parts inside the compressor. Anti-wear agents improve film strength under pressure, while advanced moisture resistance helps reduce the risk of acid formation and component degradation. These combined features help keep the A/C system running smoothly between service intervals.

• Conditioners stabilize seals and O-rings
• Inhibitors limit corrosion and breakdown
• Anti-wear chemistry improves compressor longevity

How do I use the 8oz bottle during a repair or service?

Shake the bottle briefly, then add only the amount specified by the vehicle manufacturer or the repair procedure. Use a clean dispensing adapter or syringe for accurate transfer to avoid contamination. After adding oil and refrigerant, inspect the system with an ultraviolet lamp to verify dye traces and spot any leaks.

• Measure oil requirement per service manual before adding
• Use clean tools to avoid introducing moisture or debris
• Scan system with UV light for dye traces after charging

Is this product compatible with other refrigerants or oils?

This product is formulated for 1234yf systems and is a PAG-type lubricant; it may be suitable for some R-134a systems that accept PAG 46, but it should not be mixed with POE or mineral oils unless specified by the manufacturer. Always confirm compatibility with the vehicle’s service literature before combining lubricants to avoid seal swelling or reduced performance.

• Primary use: R-1234yf systems
• May be used in R-134a only where PAG 46 is specified
• Do not mix with dissimilar oil types without guidance

Who should consider TSI Supercool 27262D? This 8oz bottle is ideal for professional technicians and DIY mechanics performing A/C repairs or targeted oil top-ups on vehicles using 1234yf refrigerant. It suits workshops that need a compact, service-ready lubricant with leak-detection dye, and vehicle owners who require a correct-viscosity PAG oil for occasional maintenance. If you’re unsure which viscosity your system needs, consult the vehicle manufacturer or an experienced A/C technician before use.
