RectorSeal Acquires All-Access Brand of HVAC Condensate Management Products

April 19, 2019

RectorSeal LLC, a manufacturer of quality HVAC/R products and operating subsidiary of CSW Industrials, Inc. (NASDAQ: CSWI), recently acquired the assets of MSD Research including its All-Access brand of air conditioning system condensate management products.

RectorSeal All-Access productsAll-Access is a leading brand of air conditioning mechanical float switches, drain line cleanout devices and supporting accessories invented by Stuart Oakner, MSD Research president. Recent revisions to the International Mechanical Code’s (IMC) condensate drain line maintenance section has increased All-Access’ popularity among HVAC service technicians, especially products featuring an easy entry cleanout design that eliminates the need to cut the 3/4-inch drain pipe for access. While All-Access complies with new construction codes, it also complements RectorSeal’s renowned retrofit-oriented Safe-T-Switch®, the HVAC industry’s leading condensate overflow cutoff switch product line.

“All-Access products will ensure we’re providing the best condensate management products to the industry, especially for new construction,” said Jeff Underwood, RectorSeal’s Vice President of Sales and Marketing.

Oakner, a former 25-year veteran HVAC contractor licensed in Florida and prolific inventor, will now assume roles of inventor-in-residence and consultant for RectorSeal as part of the acquisition. “I am pleased to be supporting the RectorSeal product development team,” said Oakner. “The vast product development resources available at RectorSeal will help support and advance the development of many future innovative products for HVAC/R and other construction industries.”

Traditional HVAC/R distributors will be able to buy All-Access products from RectorSeal, which is transitioning its marketing, sales and customer support for All-Access and merging the website into

The All-Access transaction is RectorSeal’s sixth acquisition since 2011 when it acquired Airtec, Fall River, Mass. Other recent acquisitions include Resource Conservation Technologies (AquaGuard®) electronic condensate management sensors and switches, Glue-On-Nozzle, SureSeal®, the Evo-Crete and PolySlabbrands from Australian-based Evolve Group, and AC Leak Freeze® refrigerant leak sealants. “We will continue to aggressively seek acquisitions of HVAC products that complement our current offering for contractors,” said Underwood. “We will also continue building on the model of working with inventors of great products after they sell. We see a huge value in involving them with the creation of the next generation of innovative products that will help trade people perform tasks quickly and more effectively.”
