RectorSeal® Expands Line of Adjustable Fortress® Lineset Cover Fittings

February 27, 2023

RectorSeal® LLC., a leading manufacturer of quality HVAC/R and plumbing products, is expanding its line of adjustable fittings for its Fortress cover products. RectorSeal is a wholly owned subsidiary of CSW Industrials, Inc. [NASDAQ: CSWI]. Fortress products are well known for protecting ductless HVAC linesets, wiring, and drain hoses, ensuring code compliance, and providing a differentiated aesthetic look to an install.

Today, RectorSeal announced the addition of four new fittings to its extensive line of Fortress products. Available in four satin-finish colors (white, ivory, brown, and gray) to complement installation exteriors, the new fittings are UV and weather-resistant and offer a snap-together design to connect with other Fortress brand covers. Fortress products a fully paintable for additional customization.

The new adjustable fittings provide increased flexibility to an HVAC technician and can reduce the number of fittings stocked in inventory or on a service truck. The new Fortress brand fittings are available in flat and vertical configurations. The adjustable flat fittings allow an installer to change directions on a wall surface. The vertical fittings should be used to change direction over an edge or around a corner. Both types of fittings allow the installer to create a 45-degree to 90-degree angle using only one of the new adjustable fittings. The fittings are available in 3.5-inch and 4.5-inch sizes.

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.
