RectorSeal® Adds New Lineset Insulation Products for Complete Code Compliant Air Leakage Offering

March 24, 2023

RectorSeal LLC., a leading manufacturer of quality HVAC/R and plumbing accessories, has announced the release of new code-compliant HVAC lineset jackets offering protection from wind, code compliant UV rays, and abrasion. RectorSeal is a wholly owned subsidiary of CSW Industrials, Inc. [NASDAQ: CSWI].

With the growth of new building code regulations requiring the protection of foam insulation on HVAC linesets, RectorSeal now offers durable UV-resistant PVC foam insulation jackets providing a simple, easy, and compliant solution for HVAC contractors. The innovative hook and loop fastening system is bonded and sewn for extra adherence. That allows the lineset insulation jackets to be both removable and reusable for easy installation and maintenance. Available in three wall sizes, the system lineset jackets are designed to fit residential and commercial ducted and ductless HVAC systems.

Additional features of the lineset jackets include a Class II Vapor Retarder Per ASTM-E96 Water/Vapor Permeability Test. Further, they provide a secure, breathable, tight fit, covering multiple lineset diameters, and do not fray when cut to size.

“The addition of our new lineset jackets is a perfect complement to our Outset Seal products,” said Jeff Underwood, Senior Vice President Sales and Marketing at RectorSeal. “We now have an end-to-end protection system for HVAC linesets from wall penetration to condensing unit. We strive to provide our customers with optimal solutions that offer added protection and code compliance regardless of the product category.”

Since 1937, RectorSeal has offered products that have built a steadily growing and loyal following among contractors due to differentiated and proven product performance. Further, the company is often the first to tackle and solve challenges professional trade contractors face.
