Product Description
Twelve pre-charged 0.25 oz syringes of HCPRO Performance HCLEAK12R Automotive A/C Leak Sealer — built for shop teams running fleet PM, mobile A/C service routes, and high-volume R-134a and R-1234yf repair. Each syringe seals one micro-leak or pre-treats one vehicle. One kit covers a full week of service calls or a fleet of twelve vehicles.
What's in the kit
12 individually sealed 0.25 oz refrigerant-soluble sealant syringes plus one re-usable 45° swivel low-side adapter. Pre-charged formula injects directly into the running A/C system through the low-side service port — no refrigerant recovery, no system disassembly, no separate tools required. The 45° swivel adapter is engineered for tight engine compartments where straight fittings won't reach. Compatible with R-134a, R-1234yf, and all current hybrid and EV refrigerants. Safe for PAG, POE, ester, and mineral oils.
Who it's built for
Mobile A/C service techs, dealership service writers, fleet maintenance managers, mechanic shops running R-134a and R-1234yf systems side-by-side, and DIY techs servicing personal hybrids and EVs. Equally suited to repair calls AND preventive maintenance — see below.
When to use it — repair AND preventive maintenance
Active repair: Inject one syringe when a customer reports warm air at the vent and the gauge shows slow pressure loss consistent with a micro-leak. Restores cooling without a $1,500 compressor replacement.
Preventive maintenance — the main reason this ships in 12-packs: Inject one syringe during annual fleet PM, seasonal A/C service, or new-vehicle commissioning to seal pinhole leaks before they drop pressure. Standard practice on dealership PDI inspections, rental fleets, ride-share vehicles, and any hybrid or EV where compressor replacement runs $2,000+. A proactive seal at $5 per dose prevents a catastrophic failure 18 months later.
Why it works
Pre-charged refrigerant-soluble chemistry circulates with the refrigerant and reacts ONLY at leak points where it contacts atmosphere — it does NOT clog TXVs, orifices, or evaporator coils like cheap stop-leak products. Anti-corrosion additive package prevents the underlying corrosion that caused the leak from spreading. Rated to 800 PSI for high-pressure modern systems. Manufactured in the USA to OEM-spec quality control.
