Product Details

Tired of sweltering in your car on hot days? With our industrial replacement refrigerant, you’ll feel like winter has returned every time you turn on the A/C.

Key Features & Benefits

  • Each can = 21 oz equivalent of standard R134a — you get more cooling power per can. 

  • Can be charged under vacuum — ideal for dual-air and large vehicle systems like SUVs, trucks, and vans.

  • Coldest cooling available in automotive use for extreme heat & high humidity conditions (approx. 5°F colder than Enviro-Safe’s R134a Replacement with Dye)

  • Lower head pressure & improved performance — harder work for your A/C system is reduced. 

  • Compatible with most refrigerant oils — fits well with existing A/C components and lubrication requirements.

  • Non-ozone depleting, no added global warming concerns, uses standard R134a service threads — makes transitions easier. 

  • Up to 60% less refrigerant needed compared to using standard R134a alone. 

  • Made in the USA with over 30 years of hydrocarbon refrigerant expertise. 

Best Use Cases

  • Larger automotive systems: SUVs, dual-air, trucks, Suburbans, etc. 

  • Commercial / agricultural: tractors, combines, places with a lot of glass or big cabs where loads heat up fast. 

  • Indoor applications already running on R134a, or systems retrofitted to use R134a. 

Safety & Important Warnings

  • NOT for ammonia systems 

  • Product is flammable — handle with care. Open flame, sparks, and smoking near product are prohibited. 

  • Do not overcharge system; low-side pressure should not exceed ~60 psi. 

Directions for Use (Summarized)

  1. Repair all existing leaks before charging.

  2. Recover old refrigerant from system.

  3. With compressor OFF, connect gauges.

  4. Invert can and charge liquid into low-pressure side.
