TSI Supercool PAG 46 1234yf A/C Lubricant 8 oz with UV Dye, Synthetic Oil and Anti-wear Protection

TSI Supercool 27262D is an 8 oz synthetic PAG 46 lubricant with integrated UV dye, formulated for automotive A/C systems that use 1234yf refrigerant to improve lubrication and simplify leak detection.

This specially blended synthetic polyalkylene glycol (PAG) oil offers a 46 cSt viscosity designed to meet the lubrication needs of modern 1234yf air conditioning compressors while resisting moisture pickup. It includes corrosion inhibitors, conditioners and anti-wear additives to protect internal pump and bearing surfaces, and the built-in UV tracer makes locating refrigerant leaks faster during service. The product is supplied in an easy-to-use 8-ounce bottle suitable for topping off or small repairs.

How will this oil help protect my 1234yf A/C compressor?

The PAG 46 formulation supplies consistent film strength and friction control that help minimize wear on moving components inside the compressor. Its anti-wear package and conditioners maintain internal surface protection even under higher operating temperatures typical of modern systems.

• 46 cSt viscosity at 40°C for stable lubrication across temperature ranges
• Anti-wear additives reduce metal-to-metal contact
• Conditioners and inhibitors guard against corrosion and varnish
• Synthetic base resists breakdown compared with conventional oils

Can I use this product for leak detection and how effective is the UV dye?

The built-in UV tracer makes fluorescent dye visible under a UV lamp, speeding identification of refrigerant lines, hose connections and seal leaks. It’s intended to be used with standard UV inspection lights during routine diagnostics or after repairs to confirm system integrity.

• Integrated UV dye disperses with the lubricant throughout the A/C system
• Works with handheld UV lamps to reveal leak points quickly
• Reduces time spent searching for slow or intermittent leaks
• Compatible with common inspection procedures used by technicians

Is this oil compatible with other refrigerant systems and oils?

TSI Supercool PAG 46 is formulated specifically for systems using 1234yf refrigerant and is also labeled as safe for use in many R134a applications. Because PAG oils are chemically different from mineral or POE oils, mixing with incompatible oils can cause contamination; always follow manufacturer guidance for cross-compatibility and system flush procedures when changing lubricant types.

• Designed primarily for 1234yf A/C systems
• Listed as safe for use in many R134a systems—verify vehicle specs first
• Avoid mixing with mineral oils or incompatible lubricants without proper flushing
• Best used as part of a controlled service or repair routine

What size and packaging details should I expect for routine maintenance?

This product comes as an 8-ounce single-pack bottle, sized for topping off or small-volume repairs rather than full system overhauls. The small container is convenient for service technicians or DIYers performing targeted oil additions or when introducing UV dye for diagnostics.

• 8 oz (approximately 236 milliliters) bottle for easy handling
• Single-pack format ideal for spot service and diagnostics
• Compact packaging fits toolboxes and service carts
• Clear or labeled bottle aids in dosing and inventory control

Who is this for: Technicians, automotive service shops and knowledgeable DIYers working on passenger vehicle air conditioning systems that specify 1234yf (and compatible R134a) refrigerants. This product is aimed at professionals and experienced hobbyists who need a reliable synthetic PAG 46 lubricant with UV dye for leak detection, moisture resistance and long-lasting compressor protection. Always consult the vehicle manufacturer’s service manual and follow proper safety and disposal procedures when servicing A/C systems.
