TSI Supercool PAG Oil 46 Viscosity with UV Dye — 8 oz Bottles, 6-Pack for R134a A/C Systems

TSI Supercool P46-8D PAG 46 is a synthetic lubricant formulated for R134a HVAC systems, combining 46-grade viscosity with UV dye in 8-ounce bottles sold as a six-pack.

This six-pack of 8 oz bottles delivers a high-performance PAG lubricant engineered for automotive and mobile A/C systems using R134a refrigerant. The formula is designed to resist moisture uptake, slow deposit formation, and reduce wear inside compressors. Integrated UV dye helps technicians locate leaks quickly under inspection light, while additives maintain system cleanliness and support long-term operational stability. Each bottle is compatible for top-off with equivalent OEM and aftermarket fluids, making it practical for routine service and repairs.

How does this oil protect my A/C compressor?

The P46-8D blend uses wear inhibitors and friction modifiers to reduce metal-on-metal contact inside compressors, lowering the rate of mechanical wear. Anti-oxidant components help prevent sludge and varnish build-up that can impede moving parts and valves.

• Anti-wear agents reduce internal component abrasion.
• Friction modifiers improve mechanical efficiency and performance.
• Anti-oxidants limit deposit formation and extend fluid life.
• 46-grade viscosity maintains proper lubrication across operating temperatures.

Will the UV dye help me find refrigerant leaks?

Yes — the integrated U/V dye is visible under a UV inspection lamp and makes locating small leaks faster and more accurate. The dye is blended to remain compatible with the lubricant base so it does not adversely affect lubrication properties.

• UV-dye infused for quicker leak detection during diagnostics.
• Formulated to stay dissolved and not impede lubricant performance.
• Saves technician time compared with dye-free oils in leak searches.
• Suitable for standard UV inspection workflows used with R134a systems.

Is this oil compatible with my R134a system and OEM requirements?

TSI Supercool P46-8D is engineered for systems using R134a and meets common OEM performance expectations for synthetic PAG oils. It is intended for topping off and routine maintenance where OEM-equivalent lubricants are specified.

• Specifically formulated for R134a refrigerant applications.
• Top-off compatible with corresponding OEM and aftermarket fluids.
• Manufactured to meet practical service conditions and industry standards.
• Sold in convenient 8 oz bottles for precise servicing volumes.

How does it handle moisture and long-term system cleanliness?

The formula provides improved resistance to moisture absorption compared with non-synthetic fluids, reducing risks of hydrolysis and acid formation. Its antioxidant package helps limit the accumulation of varnish and sludge that can shorten component life and reduce heat-transfer efficiency.

• Enhanced moisture resistance lowers corrosion and acid risk.
• Anti-oxidants reduce sludge and deposit buildup over time.
• Helps preserve heat-transfer surfaces and valve function for better performance.
• Supports longer fluid life and extended service intervals when used correctly.

Who this is for: Professional technicians and DIY mechanics who service R134a automotive or mobile A/C systems and need a reliable, OEM-compatible PAG 46 lubricant with leak-detecting UV dye. The six-pack of 8 oz bottles is convenient for technicians who perform multiple small service jobs, fleet maintenance teams, and anyone wanting an easy-to-store supply for topping off compressors and systems while maintaining cleanliness and performance.
