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.
 

GWR’s new SUPER STOP LEAK "Plus" is specifically formulated to prevent leaks and repair existing leaks... while revitalizing gaskets and o-rings with patented lubricates. Because of its liquid consistency, you install it just like standard A/C oil. A technician simply uses an A/C oil injector tool to install through the low side service port but you can also draw it through the center tap on a set of manifold gauges, if you prefer. This means the system does not need to be evacuated to use our product, another time saver! Simply start the engine or system, turn the A/C to maximum cooling, install SUPER STOP LEAK "Plus" and recharge the system with R-134A, R-12, R22 or R410A as per the service manual. Make it part of your maintenance service... add SUPER STOP LEAK "Plus" to every A/C service and keep systems at optimum performance levels.
 

Additional Service Products for Professional Installers

IMPORTANT:
Can a consumer install GWR's Stop Leak Plus?

This professional product is not something you can buy at a local auto parts store, or take home for a simple installation. On the other hand, a mechanically inclined person could use the Super Stop Leak Plus if they are familiar with A/C repair and have the required tools necessary to test and install the product correctly. At the very minimum, you will need the oil injector tool used by shops for the last 30 years, to put refrigerant oil into A/C systems. Additionally, you should have a set of manifold gauges and a pump to pull the vacuum for testing leak down time.

How does it work?

GWR's Stop Leak Plus is an inert mixture of specific Super Oils and our proprietary Micro Particulate Solids. Once installed in a closed circuit, it disperses and diffuses throughout the A/C system where it remains in a suspension until needed. Based on several conditions present in the system (i.e. flow, pressure, venturi action around pin holes, etc), it seeks out leaks and migrates through small holes as exiting Freon and oil create little venturi like Black Holes of suction. During the migration through the hole, our particulate begins to build and build to form a chemical weld that seals the leak. This "patch" never hardens, but remains pliable so it can flex with expansion and contraction of a system.

How large a leak will it repair?

In general, Super Stop Leak Plus is designed to seal an A/C system that has slow leaks, taking weeks or months to show up. The system must be able to hold a vacuum on the low side for 45 minutes, at a minimum. If the vacuum leaks out or changes, within an hour, the hole is too large to be sealed and manual repairs need to be made.

Will it seal evaporator leaks?

Yes, plus it will also seal leaks in the condenser. Additionally, the special oils will rejuvenate all connection hoses, gaskets and o-rings. The only part of a system where a leak can not be repaired is a compressor shaft seal. All seals are designed in a way that leaks are inevitable because shafts that go through them, continually turns at the seal's mating lip.

How much do I use?

One 2 oz. bottle is all that is necessary to seal and condition one average size vehicle’s A/C system. When adding Super Stop Leak Plus to an evacuated empty system, substitute one bottle of Super Stop Leak Plus for 2 oz. of the regular A/C oil. (i.e. A 10 oz regular fill is now 8 oz's oil and one bottle of Super Stop Leak Plus). If the vehicle has a slow leak but still has a partial charge at service time, simply add one bottle of Super Stop Leak Plus along with the required amount of refrigerant until the system meets factory specs for a new charge. (Per service manual specifications)

Is it available for both R-134A and R-12 systems?

Yes! There is a Super Stop Leak Plus for both R-12 and 134A A/C systems, plus it works with blended refrigerants as well. Be sure to specify either the R-12 or 134A version when dealing with automotive applications, to match system being serviced.

What about commercial or home A/C systems?

We do have additional formulas for home, commercial and industrial refrigeration systems. These unique products are revolutionary and just as easy to use as our automotive versions. Product specific versions for R22 and R410A are available in bulk gallons, for installation by professional service companies. (Please note we do not have single application bottles available for consumers, or DIY customers.)
