Product Description
Universal PAG oil with built-in UV dye for R-134a A/C leak detection — formulated to blend with PAG 46, PAG 100, and PAG 150 systems. When you don't know what's in the compressor and you're chasing an intermittent leak, this is the bottle that goes in. Top off, run the system, and the dye shows you the leak under any UV light. Skip the separate dye injector, skip the dosing math.
HCPRO Performance Universal UV PAG is an 8 oz / 237 mL automotive A/C compressor lubricant + fluorescent leak detection additive. Universal viscosity blend (~46–100 cSt) mixes with any existing PAG grade. Built-in dye meets SAE J2297 UV detection standard. For R-134a systems in domestic and imported autos, light-duty trucks, and standard service equipment. NOT for R-1234yf, hybrid, or EV compressors.
Who this oil is for
Auto A/C techs chasing intermittent R-134a leaks. Mobile mechanics doing recharges where systems lose charge between visits. Fleet techs servicing mixed inventories where OEM PAG spec isn't always known. Independent shops that want one universal bottle instead of three viscosities.
When to use it
Add during recharge to diagnose slow leaks you can't visually locate. Inject 1–2 oz per circuit for diagnostic; refer to OEM spec for full compressor replacement (4–8 oz typical). Run A/C 10–15 minutes, inspect with UV light (365–400 nm) — leaks glow fluorescent green-yellow at fittings and seals. 8 oz covers 4–8 diagnostic jobs.
Why universal UV PAG vs grade-specific PAG
One bottle covers any PAG 46/100/150 system — no need to stock three viscosities. Built-in dye eliminates separate injection. For a known OEM viscosity spec, use grade-specific PAG (46/100/150 UV); for unknown systems or universal top-off, this is the answer.
Single 8 oz bottle, moisture-sealed packaging. Manufactured in the USA to OEM compressor lubricant performance standards.
