Our unique additive oils lubricate all moving metal parts in the AC system, while revitalizing O-Ring elasticity. More remarkably though, our patented Micro Particulate Solids seal hard to find leaks in evaporators, condensers, hoses and other difficult to repair AC components. Don't spend hundred or even thousands to replace expensive parts only to find out you missed a small pin hole elsewhere and now all the new gas has leaked out.

AC Stop Leak Plus can be use as a tune-up conditioner during a Freon top-off when components are in overall good shape, or as a complete system rejuvenator when Freon and oil are added during a major repair or service.

Programs are available for all levels of distribution to professional technicians, from single cases for automotive applications to gallon containers for HVAC commercial use. We even offer the specialized tools needed for installation, simply scroll down the page to learn more about them.

For those of you wondering, GWR Stop Leak Plus is not activated by air, moisture or Freon like the common products found at the Auto Parts store or HVAC supply houses!

It is not polymer based and will not harden. It simply remains as a base oil in the system after installation and never "converts" like the problem type sealants.


If a sealer comes in a pressurized metal can, don't use it! Period!

They all set by moisture or Freon contact and that means they will clog a system and or recycling machine once they touch air inside the unit. Watch out for the words "Inert", "Activated", "Forms a Chemical Weld" these are the dead give away it is a polymer!

But what about the little plastic bottles I'm beginning to see on the internet, aren't they the same as yours?

These are the Johnny come lately copies of our Patented AC Stop Leak Plus! Ones that look like liquid (red, yellow, etc) are mineral oil based and have zero solids (seal swellers type), or they contain powdered calcium or silicate solids that stick together and form large blobs of floating debris in a system. As you may be able to visualize, neither idea is good! They will either weaken rubber parts, have no effect at all, or the larger particles will clog the filters, orifices, capillary tubes and other parts of the AC System.
