Tips from the Pro

Post: If I use a universal gauge on a piercing valve can, can I remove the gauge before I’ve used the entire can without leaking the remaining refrigerant into the atmosphere?

No. Unfortunately while our new univeral gauges work with both types of valve systems, they do not make a piercing valve act like a self-sealing valve. If you are using a piercing can, you will want to keep your gauge attached to the can until it is depleted.

Post: What color are the caps on the low pressure port and high pressure port?

Unfortunately, the caps on the high and low pressure automotive air conditioning service ports vary. In most cases, both caps will be black, but we have also seen them in grey, blue, and green. Sometimes they have an “H” or “L” to indicate High or Low pressure ports. Wondering where your car or truck’s low-pressure port is located? Use our Port Locator.

Post: Can I add refrigerant to my vehicle when it is cold outside?

In order to properly charge you automotive A/C system the ambient temperature should be above 65ºF. Anything below that does not allow the system to build up enough pressure for a proper reading on your A/C Pro pressure gauge. Because of this, adding refrigerant to your vehicle is not recommended when the ambient temperature is under 65ºF.

Post: Can I use A/C Pro in my hybrid vehicle’s electric compressor?

No; if your car or truck has a fully electric compressor you can ONLY use straight refrigerant and ONLY approved hybrid vehicle lubricant. You cannot use any products that have additives that are not specifically formulated for use in hybrid vehicles. If you are unsure, we recommend checking with your vehicle manufacturer. We do carry a hybrid-specific oil that can be used with straight r-134a gas, which you can find here. We still recommend you check with…

Post: Can I use your products in my hybrid vehicle?

If the vehicle has a fully electric compressor (no belt-driven pulley) then you cannot use any of our products with additives. As a rule of thumb, on hybrid vehicles you should ONLY use hybrid lubricant and straight refrigerant. If you have a hybrid vehicle that has a belt-driven compressor and the tag under the hood says the system uses PAG oil then you would be ok to use any of our products.

Post: How does Super Seal work?

While in the air conditioning system, it remains a liquid lubricant and contains additives to penetrate and rejuvenate o-rings, gaskets and other rubber connectors to prevent leakage. Included in Super Seal is a drying agent that gets rid of any moisture that may be inside the air conditioner. If the refrigerant leak occurs in a metal part, the refrigerant leaves the system and chills the outside air causing condensation. This moisture activates the Super Seal fluid…

Post: How do I know Super Seal works?

Super Seal has sealed leaks in over 1,000,000 vehicles since it’s introduction in early 2000. This moisture activated sealant technology has long been used in the gas transfer industry, sealing leaks in pipes, tanks, and other gas filled containers.

Post: What size hole will Super Seal repair?

Super Seal will repair most leaks. However, if the system cannot hold a charge for 24 hours, the leak is too large and probably needs manual repair. If the system is leaking slowly and holds a charge for more than two weeks, Super Seal should seal the leak. Super Seal will seal multiple holes in both the metal and rubber parts of the air conditioning system. Super Seal is an inexpensive alternative considering a repair that…

Post: What happens to the Super Seal if all the refrigerant leaks out and air enters my AC system?

Super Seal has a lower boiling point than the refrigerant oil. This enables the Super Seal to be removed from the system as the refrigerant either leaks out or is removed.

Post: Will Super Seal clog any component of my AC system?

No. The chemical formulation remains in a liquid state inside the a/c system until it detects moisture at the leak point and self-seals. Super Seal contains a drying agent to prevent any sealing activity while in the system. Super Seal will be removed from the system with the refrigerant as it either leaks out or is removed.(See installation instructions.)
