Our unique additives lubricate all moving metal parts in an AC system, while revitalizing O-ring and seal elasticity. More remarkably though, they seal hard to find leaks in evaporators, condensers, hoses and other difficult to repair AC components. Additionally it helps to keep the lines and compressor clean by preventing acid formation that leads to oxidation. It has the ability to control humidity also, special oils modify moisture so that it does not retain damaging properties. By controlling all these detrimental components, we lower vent temperatures, extend life of system and even improve cabin comfort levels. 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.
Stop Leak Plus can be use as a tune-up
"conditioner" during a maintenance refrigerant top-off when components are in overall good
shape, or as a complete system rejuvenator when new gas 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 commercial HVAC use. We even offer the specialized tools needed for installation, you can see more about them on additional pages and the FAQ section.
For those of you
Here are two consumer reviews
These are the liquid type Stop Leaks in Plastic Bottles...
We're #1 for a reason!
The end view of a solenoid valve from an evacuation machine,
notice the hardened particles of another 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 and another repair is required to remove the bad sealer
and the parts that have been damaged.
Simply stated... This is the finest A/C Stop Leak / Conditioning Treatment on the market!
Still concerned about using Stop Leak Plus?
believe this expert testimony definitively answers the question
everyone with a leak eventually asks.
When ask "Will a Stop Leak Sealer cause damage to A/C Systems?"
"Since the introduction of AC sealers several years ago, we noticed a drop in evaporator sales but an increase in compressor sales, especially for older vehicles.
I attribute that to the fact that a sealer makes an AC job affordable when there is a leaky evaporator and compressor. Since the sealers do a good job on evaporator leaks, but won't seal compressor shaft seals, we are finding customers generally authorize a replacement compressor and the stop leak sealant.
In my examination of over 2,000 returned compressors over the years, I have not noticed a significant problem with sealants. In fact, less than ten units showed congealed sealant at all. Upon closer examination, in only a few cases could the congealed sealant be determined to be the cause of the failure. And this was no doubt due to the technician failing to replace the dryer and leaving moisture in the system during servicing.
Additionally, in just the last 3 month summer sales season, we sold over 460 compressors and did not receive even a single return due to sealers."

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 and lowering temperatures with
proprietary technology. 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 standard 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.
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.
These extremely high quality professional tools
are available from GWR, starting in the $50 range.
How does it work?
Super Stop Leak Plus is an inert liquid mix of unique oils and proprietary solids that is injected into a refrigeration system. Once installed in a closed circuit, it travels freely through the system and actively address a half dozen different issues at the same time. As it floats along with the refrigerant, it seeks out leaks and migrates through small holes by way of the venturi effect created by the escaping gas. During the migration through the hole, it is pressed and or sucked into the irregular shaped opening to form a permanent plug that seals the leak. This "patch" never hardens, but remains pliable so it can flex with expansion and contraction of a system. (Note: The exclusive, variable sized, micro-particulate solids in our 20 year old patented formulation are installed at the factory, by the millions. Unlike the imitation stop leak products on the marketplace, we do not create solids inside the AC system based on and "activation process". Under no circumstances does that concept work, it only leads to clogging and blockages. You must beware of the canned products, they all work the same no matter what the label says!)
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 is lost or changes significantly within an hour, the hole or leak condition is too large to be sealed and manual repairs should 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, lower temperatures and quiet compressor noises. The only part of a system where a leak can not be repaired is a compressor shaft seal, since the parts are moving and not static. All seals are designed in a way that leaks are inevitable, shafts that go through them continually turn 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 1 oz. of the regular A/C oil. (i.e. A 10 oz regular fill is now 9 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.)
professional installers to order one of these incredible tools, they
are simple and the fastest way to inject our Super Stop Leak Plus
additive. Best of all you don't have to bring down a system, you
can inject at full system pressure based on the seal system in the
high pressure pump. Additionally, the reservoir bottle holds 16
ounces of SLP, so you do not have to stop and refill (smaller tools)
when you need to put 3, 5, 10 or more ounces into one unit.
How long will it stay in the system?
Super Stop Leak Plus forms a permanent repair when it comes into contact with venturi flow, specific temperatures, pressure, refrigerant and other parameters at one specific location. If there are no leaks in the system and you’re installing it for preventative maintenance, the product simply remains a high quality liquid lubricant until a leak is detected. Every vehicle should have a bottle installed when a major repair is performed but also on systems with no problems. It is the cheapest insurance you can buy!
What happens when I recycle the refrigerant?
Super Stop Leak Plus is removed from the A/C system with the refrigerant during standard recycling procedures. It separates from the refrigerant during evacuation and joins the reclaimed oil. Since it flows, is an oil and does not harden in a system, it will not harm or clog recycling machines during transitions.
How long has the product been on the market? Does it really work?
The Super Stop Leak Plus has been sold to the professional installer for over 15 years and installation problems are virtually non existent. The few complaints we have received are always from installers who fail to check over the system before installation of the product. When the holes are just to big or there are too many (will not hold a steady vacuum for 45 minutes), even our unique, patented sealant, may not repair a leaky system. Rely on the best sealer in the business, we guarantee there's not a better one available... anywhere in the world!
