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.

GWR's SLP is not like all the others that claim to seal A/C leaks...

We do not react to moisture and therefore do not need to come in a sealed, pressurized can like the others. It's interesting that those formulas are so volatile they sometimes even harden in the delivery tube attached to the can, while you're trying to install them. On the other hand, GWR's SLP will not clog installation equipment or the recycling machines needed to remove gasses from systems being serviced. Take a look at this picture and you will see why the products in pressurized cans are not only a problem for a recycling machine but also the system itself.

This end view picture of a solenoid valve from an evacuation machine, really demonstrates the problem!
Notice the hardened particles of a typical polymer stop leak product. These granular particulate float around in the system until they attach to a part or get trapped in a filter or expansion valve. When that happens, system efficiency is reduced or even stopped. Worse, another repair is required to remove the bad sealer and the parts that have been damaged. Don't fall for the millions spent on marketing the polymer based products! They are sold by monster companies only interested in their bottom line... not yours.

How GWR's SLP is different and why it works...

Three elements are necessary for GWR's Stop Leak Plus to work.... the Refrigerant, the system pressure and high velocity flow / movement. These actions are the "carrier" that deliver our unique proprietary Micro Particulate Solids to the point of a leak or leaks. When corrosion occurs small pin holes begins to open up in all systems, its just a matter of time. Whether pre-existing or even in the future, refrigerant and some oil escapes through those hole at a rapid rate of speed. This flow creates a spiraling venturi action that pulls in some of the Stop Leak Plus particulates that are circulating through the system. When our escaping molecules bombard the ragged edges of the hole they begin to attach to the area and each other, eventually forming a seal or patch. Of great importance, in contrast to competitors, our Stop Leak Plus particles were formulated to stay flexible and pliable after a seal is created. They will remain secure through years of on and off temperature cycles and vibrations in an HVAC system or automotive vehicle.
