K-Flex Names RectorSeal an Approved Master Distributor for HVAC/R Piping Insulation and Tapes

RectorSeal® LLC, Houston, a manufacturer and distributor of quality HVAC/R products, and part of the CSW Industrials, Inc. [Nasdaq:CSWI] group of companies, has been named an approved master distributor for K-Flex® Youngsville, N.C., one of the HVAC/R industry’s largest manufacturers of refrigerant lineset insulation and tapes for commercial and residential air conditioning and refrigeration systems.

The distribution relationship will initially comprise of three top-selling product lines manufactured by K-Flex, a 31-year-old, family-owned business with 13 international plants and a marketing reach into 43 countries. RectorSeal will distribute the following products to traditional HVAC/R wholesale distributors in the U.S. and Canada:

K-FlexTitan™–a closed cell, elastomeric foam insulation with a flexible, co-extruded UV- resistant jacketing for linesets. Titan offers UV/moisture resistance with a tough and nearly impenetrable jacket that protects piping from outdoor elements, animals and lawn care string trimmers.

Foam Tape–a NBR/PVC-based, closed cell, elastomeric tape with a factory-applied pressure sensitive adhesive that forms a long-lasting bond. It’s perfect for short pipe runs or where tubing insulation is impractical to cover, such as covering fittings or valves.

Cork Tape–a 55-percent cork-filled, rubber-based insulating tape with a grainy, rubber-like consistency. It’s also ideal for covering fittings and valves.

All three products and their energy-saving thermal dynamic characteristics comply with the International Energy Conservation Code (IECC) and International Residential Code (IRC).

K-Flex’s product lines complement RectorSeal’s ductless mini-split, VRF/VRV and conventional air conditioning accessories. “We see RectorSeal as a leading HVAC/R manufacturer that also has an excellent distribution footprint,” said Matt Hair, K-Flex’s North American director of sales. “They presented an exciting vision for our products’ sales growth that would benefit our company as well as the industry. RectorSeal’s demonstrated success as a provider of comprehensive line of accessories leads wholesalers and contractors to their website to find products, such as lineset insulation and tapes.”

“This relationship expands our product line, but more importantly it allows our independent distributors to now execute smaller quantities of K-Flex within their Rectorseal orders without incurring large inventories and separate freight charges,” said Jeff Underwood, RectorSeal’s vice president—sales and marketing. “Our ultimate goal is to make it easy for distributors to do business with us.”

The three product lines are the inaugurating foundation for the partnering, however Hair sees great potential in RectorSeal adding more of K-Flex’s existing and in-development product lines in the future.
