Enviro-Safe R134a Replacement Refrigerant with Stop Leak – 12 Can(s), 8 oz Each | Better Cooling, Lower Cost, Leak Protection
A Smarter Way to Recharge Your A/C
If your vehicle or small A/C unit is losing cooling performance, Enviro-Safe® R134a Replacement Refrigerant with Stop Leak is the solution you’ve been waiting for. Developed for automotive systems and compatible with most standard R134a applications, this refrigerant is engineered to cool better, last longer, and save you money.
Unlike standard R134a, Enviro-Safe’s formula is highly efficient — one 8 oz can replaces over 21 oz of R134a, meaning you’ll use up to 60% less product to achieve the same cooling results. That translates to fewer cans, less waste, and more value per recharge.
Built-In Stop Leak Protection
This version comes with a Stop Leak additive, designed to help seal minor leaks in your system’s rubber components — including o-rings, hoses, and gaskets. Instead of constantly recharging, this formula works to slow refrigerant loss and keep your system sealed tighter for longer.

Safety First
This product is flammable to open flame or spark and should be handled with care. Always use in well-ventilated areas, away from cigarettes, sparks, or flames.
-
Only install through the low-pressure port (larger diameter line).
-
Do not exceed 60 psi on the low side — overcharging may damage your compressor.
-
Always repair major leaks before charging.
-
Use proper leak detection methods (UV dye, electronic hydrocarbon detector, or soap bubbles).
-
Refer to your vehicle or equipment manufacturer’s specifications for proper charge levels.
How to Use (Step-By-Step)
-
Turn off the compressor and recover any existing refrigerant.
-
Inspect and repair the system for leaks.
-
Connect gauges and hoses to the low-pressure side (compressor off).
-
Invert the can and begin charging liquid refrigerant into the system.
-
After a partial charge, test for leaks. If no leaks are found, turn on compressor to high and continue filling.
-
Stop filling when pressures and temperatures match manufacturer specifications (do not exceed 60 psi).
-
Disconnect gauges, install service caps, and apply a system label in a visible location.
⚠️ Overcharging can reduce cooling performance and cause damage. Always charge by specifications — not by “clearing the sight glass.”
👉 Pro Tip: For best results, pair with an Enviro-Safe Dye Charge or leak detection kit so you can visually confirm your system is sealed tight before finishing your recharge.
