COLUMBIA, Md., Jan. 17, 2018 /PRNewswire/ — The newest innovation from Cool Air Products ( offers an  external leak-stopping solution that’s both easy to apply and suitable for any material. AC/SMARTSEAL EXTERNAL is a putty-like compound that creates a strong seal with no mess and no need for a flame. The product is compatible with all lubricants and refrigerant gases, and leaves no residue in the lines.

«The responses to AC/SMARTSEAL EXTERNAL from the market have exceeded expectations,» says Cool Air Products President Mike Walton. «There is not another product like this in today’s HVAC/R industry. Our company has been able to attract loyal contractors because of our ability to quickly produce and deliver new, innovative products. Our philosophy is to take direct feedback from product users, and turn the feedback into quality products with those users in mind.»

AC/SMARTSEAL EXTERNAL works flawlessly within a temperature range of -148 to 520 degrees F. The material is inert and cures quickly. It’s capable of sealing leaks up to 5mm and pressure  up to 825 psi. Once applied, the product forms a permanent seal. While every repair is different, AC/SMARTSEAL EXTERNAL has been designed to be as versatile as possible, making the product an indispensable part of any HVAC/R repair toolkit.

No tools or additives are required to apply AC/SMARTSEAL EXTERNAL i Repair technicians should first locate leaks using the standard methods. Next, the system must be deactivated, and the application area cleaned. Technicians should cut off just enough AC/SMARTSEAL EXTERNAL to form a ring around the pipe’s entire diameter and cover 0.5 inches on all sides of the leak. The two components must be mixed together with fingers until the color becomes a uniform grey. The putty also generates a slight warmth as the chemical reaction takes place. After applying AC/SMARTSEAL EXTERNAL as directed, technicians should ideally wait a few hours before powering up the system. Optionally, a heat gun can accelerate the curing process to as fast as 45 minutes.

AC/SMARTSEAL EXTERNAL and AC/SMARTSEAL (for internal leak repair) can be used together — the products are not just compatible, but in fact reinforce each other’s effectiveness. Once completely cured, the surface seal can be sanded to a smooth finish. If removal is necessary, grease/seal remover and pliers will do the trick.
