RectorSeal® acquires AC Leak Freeze™

Share With:

Houston — RectorSeal® Corp., a manufacturer of quality HVAC/R products, acquired the assets of Universal Technologies Inc., Baltimore, Md., and its AC Leak Freeze™ brands of refrigeration and air conditioning system leak repair sealants on Dec. 16.

Universal Technologies is a leader in the booming refrigerant leak repair industry for most sizes of air conditioning and refrigeration equipment under the AC Leak Freeze™ and AC Leak Freeze™ with Magic Frost brands. It also offers AC Leak Freeze™ R for smaller appliances. AC Leak Freeze is a non-polymer formula that seals environmentally-damaging refrigerant leaks internally and doesn’t react to moisture or oxygen. Once applied with its industry-unique injector system, AC Leak Freeze also remains in the system to seal future leaks as they occur, while also reducing component friction.

The acquisition supplements RectorSeal’s expansive product line and complements its refrigerant service product category that includes, Acid-Away®, Acid-Detector™ and Oil-ID™. “We had the opportunity to buy a company with a ‘best-in-class’ product, so we took advantage of it,” said Larry Kaiser, vice president–sales, RectorSeal, a portfolio company of publicly-traded CSW Industrials, Inc. (Nasdaq:CSWI), Dallas.

Traditional HVAC/R wholesalers and contractors will experience a seamless, unnoticeable changeover when RectorSeal transitions to marketing, sales and customer support of AC Leak Freeze™ and its website,

The Universal Technologies transaction is RectorSeal’s fifth acquisition since 2011 when it acquired Airtec, Fall River, Mass. Other recent acquisitions include Resource Conservation Technologies, Glue-On-Nozzle,  SureSeal®, and the Evo-Crete™ and PolySlab™ brands from Australian-based Evolve Group.
