Product Info

 

AC SmartSeal External™ has been developed to be compatible with POE, PAG, PAO, minerals lubricants and alkylbenzene, and also with the following refrigerants:

  • CFC

  • HFC

  • HCFC

  • CO

  • It has also been tested for new generation gases such as R1234yf and R1234ze.
     

AC SmartSeal External™ is also resistant to normal flushing liquids, and is resistant to temperatures from -100 ° C to + 270 ° C.

​

The pressure resistance depends on the size of the loss:

​

  • 580 psi - 5 mm leak diameter

  • 725 psi - 2 mm leak diameter

  • 825 psi -1 mm leak diameter
     

AC SmartSeal External™ can be easily mixed by using two fingers. Once applied, the leak is closed. It is ideal for emergency sealing and does not disperse any residue into the system and, if necessary, it can be easily removed and once dried, the product can be sanded and refinished.

​

AC SmartSeal External™ usage can be combined with SmartSeal QuickShot. The operator can first seal the larger leak from the outside and then complete the sealing process from the inside with SmartSeal QuickShot. The two products are not only compatible, but also synergic.

Instructions for Use
 

DONE IN 5 FAST AND EASY STEPS :

 

  1. Find the leak by using the usual detection methods.
     

  2. Once the leak is identified, turn off the system, and clean the application area.
     

  3. Cut with a knife a quantity of SmartSeal External which is enough to create a ring around the entire diameter of the pipe in the area of the leak.
     

  4. Using your fingers mix the two components for a while. The color must be uniform and you should perceive a slight sensation of heat.
     

  5. Apply the mixture directly on the leak area, let it adhere to the whole circumference with about .5 inches on each side of the leak area. Wait 4-5 hours for the SmartSeal External to cure and harden. Curing can be accelerated with the use of a heat gun. Once the product is dried, let the system run normally again. If you need to remove the product, spray grease/seal remover on it, wait a moment, grab the ring with pliers or spanners with a little pressure that does not deform the pipe and rotate in one direction.

 

These are standard instructions. Like brazing, there can be many variables that come with sealing holes and cracks in the field with SmartSeal External. This includes material condition, environment, size of leak, pressure of system, and workmanship.
