Houston, TX, July 12, 2023– RectorSeal LLC, a leading manufacturer of quality HVAC/R and plumbing products, announced today the addition of a black Slimduct Lineset Protection cover to complement the current product-line offerings of white, ivory, and brown.

Slimduct premium lineset cover systems are designed to protect and conceal exposed ducted and ductless HVAC piping, wiring, and drain hoses. The four colors now available are designed to enhance any residential or commercial HVAC installation and provide a professional, finished appearance. The full complement of colors ensures a Slimduct style that aligns with current construction and building trends.

Available in standard-sized lengths and with various fittings, Slimduct lineset covers feature a unique snap-together design for quick installation, saving time and money for professional HVAC contractors. Its rigid construction is engineered for challenging installations and extreme environments. With a deeper profile, Slimduct provides more room to work and accommodates thicker lineset insulation required by many industry codes. A wider design provides ample room to cover multiple linesets, wiring, and drain hoses under one installation.

Additional Slimduct lineset cover features include:

• – Flat bottom channels and elbows that hug walls and help to eliminate insect infestation and bird nests
• – Resistant to fire and severe weather
• – UV Stabilization
• – Testing for over 2,000 hours in a temperature range of 4℉ to 14o℉
