FJC PAG 46 A/C Oil with UV Dye 32 fl oz — OE‑Viscosity PAG 46 Leak‑Detection Lubricant

FJC 2494 is a 32 fl. oz. OE‑viscosity PAG 46 air conditioning lubricant that includes a fluorescent leak‑detection dye visible under UV light.

Engineered for modern mobile A/C systems, this FJC PAG oil combines the recommended OE viscosity with an integrated UV tracer to speed up leak diagnosis and reduce downtime during service. Supplied in a 32‑fluid‑ounce container, the formulation is compatible with PAG‑based refrigerant systems and is manufactured in the United States to meet routine maintenance and repair needs.

How does the built‑in fluorescent dye simplify leak finding?

The fluorescent dye in FJC 2494 mixes with the PAG 46 carrier oil so any leaked lubricant fluoresces under a standard UV inspection light. That eliminates separate dye‑injection steps and helps technicians spot leaks faster without extra mess or equipment. For best visibility, inspect the system after a full‑charge service or normal operation.

• Dye is pre‑mixed with the oil—no separate syringes required
• Detectable with off‑the‑shelf UV lights commonly used in shops
• Max fluorescence when the system has a full oil charge
• Reduces time spent on trial‑and‑error leak searches

Is this PAG oil right for my vehicle’s A/C system?

FJC 2494 is a PAG 46 grade lubricant, matching OE viscosity recommendations for many modern automotive and light‑truck A/C systems that require PAG 46. Always check the vehicle manufacturer’s service manual or existing compressor tag to confirm PAG compatibility before adding oil. Using the specified viscosity preserves lubrication performance and helps maintain compressor life.

• OE viscosity: PAG 46—suitable where manufacturer specifies this grade
• Designed for mobile automotive and light‑truck systems using PAG oil
• Not for mineral oil or POE‑specific systems without confirmation
• Ideal for top‑up during service or for compressor replacement jobs

How should technicians apply this product during service?

Add FJC 2494 to the A/C system following standard service procedures: evacuate, recharge, and then introduce the oil amount specified by the manufacturer. The integrated UV dye works best when the system has been returned to a normal charge and has circulated oil through components. Use proper PPE and containment to avoid spills and to keep the work area clean.

• Add oil in measured amounts according to the vehicle service manual
• Circulate system after recharge for dye distribution and inspection
• Inspect under UV light to locate any fluorescent traces of leakage
• Store upright in original container; follow local disposal rules for used oil

What are the product’s physical and sourcing details?

FJC 2494 ships as a 32 fl. oz. bottle and carries a package weight of about 2.1 pounds. The product is made in the United States and packaged in compact dimensions suitable for shop storage. It’s formulated so common UV lamps used by technicians will reveal dye traces at leak points.

• Volume: 32 fluid ounces (946 mL)
• Package dimensions approximately 6.35 H x 12.953 L x 12.953 W centimetres
• Package weight: 2.1 pounds
• Country of origin: United States

Who is this for? FJC 2494 is intended for professional technicians and serious DIYers who service PAG‑based automotive A/C systems and want an OE‑viscosity lubricant with an integrated UV tracer to speed leak diagnosis. It’s useful for routine maintenance, compressor installations, and any repair scenario where quick, reliable leak detection reduces labor time and repeat visits. Always verify system compatibility and follow vehicle manufacturer oil fill recommendations before use.
