A two-can recharge kit that replaces R134a or R12 refrigerant in older automotive A/C systems. It includes a color-coded gauge hose, oil, a low-side service fitting and a decal, so a DIY top-up needs no separate parts. RED TEK 12a is a hydrocarbon blend that runs at lower head pressure than R134a, which many owners say cools well. It is not for vehicles on R1234yf, and mixing it with leftover R134a is a known risk.

Owners of older cars report strong cooling after a recharge and like that the kit covers the whole job. Technicians warn about mixing it with R134a and about shops refusing to recover it.
The RED TEK 300 A/C Refrigerant Recharge Kit is a direct replacement and retrofit option for R134a and R12 refrigerants in automotive air conditioning systems. It is a freon replacement that runs cooler and more efficiently, and it does not deplete ozone.
No license or retrofitting is required to use it. It carries EcoSafe certification (non ozone depleting). The kit includes everything needed to properly charge an air conditioning system.
This refrigerant is not compatible with vehicles that run 1234YF A/C systems.
