HCPRO PAG 100 UV Dye is a high-viscosity synthetic A/C compressor oil with integrated UV tracer for fast, reliable leak detection and durable compressor protection.

This professional-grade PAG 100 lubricant combines high-viscosity synthetic oil with a built-in ultraviolet dye so technicians and experienced DIYers can spot refrigerant leaks quickly while restoring proper lubrication to automotive air conditioning compressors. Formulated to meet the needs of modern automotive systems, it supports system performance, reduces wear, and serves as a versatile option for several PAG viscosity requirements.

How does the UV dye help locate A/C leaks?

The oil contains a fluorescent tracer that becomes visible under a UV inspection lamp, making small leaks easier to find without disassembling the system. It highlights escape points in hoses, fittings, seals, and connections so you can target repairs precisely.

  • Integrated dye shines under UV light for quick visual diagnostics
  • Makes slow or intermittent leaks easier to identify
  • Reduces time spent on manual inspection and guesswork

Will this PAG 100 oil protect my compressor and improve performance?

Yes—the high-viscosity synthetic base provides consistent film strength and lubrication across operating temperatures, helping reduce metal-on-metal wear and improving thermal stability. That consistent lubrication supports smoother compressor operation and contributes to longer component life when used as part of routine maintenance.

  • High-viscosity formula maintains protective oil film under load
  • Designed to resist breakdown at elevated operating temperatures
  • Helps maintain compressor efficiency and reduce mechanical wear

Is HCPRO PAG 100 UV Dye compatible with other PAG viscosities and common service uses?

This formulation can serve as a practical replacement option for several PAG grades, giving flexibility in recharges and top-ups. Professionals often use it for A/C recharges, compressor protection during repairs, and system maintenance where a higher-viscosity oil is required.

  • Suitable alternative for PAG-46, PAG-100, and PAG-150 service needs
  • Useful for recharges, compressor swaps, and leak-trace diagnostics
  • Manufactured for automotive A/C systems using PAG refrigerant oils

How should I use this product safely and effectively?

Follow vehicle manufacturer recommendations for oil type and volume before adding oil. Use a UV lamp to inspect after system operation and always handle refrigerants and oils with appropriate PPE; consult professional service if unsure.

  • Confirm OEM oil viscosity and fill volume before use
  • Apply dye-oil during recharge or compressor service per guidelines
  • Inspect with a UV lamp after system runs to identify leaks

Who is this for: HCPRO PAG 100 UV Dye is designed for professional mechanics, A/C specialists, and experienced DIY automotive enthusiasts who need a high-viscosity, leak-detecting lubricant for modern A/C compressors. It fits scenarios where reliable lubrication and fast visual leak tracing are priorities—ideal for shop diagnostics, repair workflows, and preventative maintenance on vehicles that require PAG-type refrigerant oils.

FAQ

Q: Can HCPRO PAG 100 UV Dye be mixed with other PAG oils?

A: Yes, it can be blended with other PAG oils, but follow OEM guidance and maintain correct viscosity for your system.

Q: Will the UV dye affect A/C system performance?

A: No—when used in recommended amounts, the dye aids detection without compromising lubrication or system operation.
