Product Description

 One (1) can of Automotive Air Conditioning Stop Leak which is used to seal leaks in O'Rings & Seals in autos/trucks/vans/ect AC systems which hold up to a 4 lbs . Will repair most small leaks in evaporators and condenser o'rings and seals. Just tap the can, purge the hose (allow a small amount of refrigerant out the end of the hose to remove air from the hose) attach hose to suction side (low side) of system while running and the compressor will pull the stop leak/refrigerant into the entire system and seek out the leak. Stop Leak  is compatible with any oil or refrigerant (freon) including R134A and R12A and will also charge the system with approxitmately 7.5 oz of Freon (1 oz is the equivalent of 2.5 oz) These items are brand new and made by Envirosafe Refrigerants Inc. Installed on the low side of the system with the can upside down.  Would need a regular 134A automotive tap can hose to install when the vehicle has 134A fittings  or a R12A tap can hose if the vehicle has R12A fittings usually when installing in a older system. We also sell tap can hoses.  Use this product myself and works great.  Must be shipped USPS Parcel Post Ground or Fed Ex Ground due to being an aerosol. Made in the USA. Please Note: If air or moisture is suspected in the system, you should add a can of Pro Dry which is also available in our listings. If metal fittings are leaking you should use Pro Seal which is also available in our store.

  • Many leaks in A/C units occur within the O ring and seal areas. As O rings and seals age, the materials begin to crack and shrink.
  • Enviro-Safe Stop Leak relubricates O rings and seals causing them to swell and thus re-seals the A/C system.
  • One can of Enviro-Safe Stop Leak repairs a system containing up to 3-4 lbs of refrigerant.
  • Works with Mineral, Ester and Pag oils.
  • For automotive use ONLY!
