Aerosol
This product is a combination of 2 Enviro-Safe products into 1 for maximum cooling performance.  This will remove moisture in the A/C system.  Moisture can cause corrosion in the A/C system or the A/C to freeze up.
Please note, the top of this can has a 134a top which means you need a hose or gauge with the proper ends in order to install this product into your 1234yf vehicle. We have hoses and gauges available under these numbers: 3600 & 3610 gauges and 3635 & 3615 hoses. Please use the search bar at the bottom of the page or look in the "Gauge & Hoses" section of our site.
The other part of the product will reduce friction in system and provide colder air duct temps in most cases.

R1234YF STOP LEAK
Aerosol
For 1234YF automotive use
The top of the can has a R134a top which means it is a right handed top so you need to make sure you have the correct hose.
With age, o rings and seals will shrink and deteriorate.
When Enviro-Safe Stop Leak is added to your a/c system, it reconditions the rubber o rings and seals.
When the Stop Leak product is installed in an air conditioning system, the product mixes with the refrigerant and oil. As the product circulates in the system, it comes in contact with the o’rings and seals causing them to swell, resulting in "no leak".
Stop Leak will not repair or "fix" cuts or worn out o’rings or seals.
1 can will treat 1 vehicle.
Installing Enviro-Safe Stop Leak may stop the yearly recharge of lost refrigerant.
Use only with Mineral, Ester, and Pag oils.
