The QUICKFLASH acu-s is an AC line set flashing panel designed to create a weathertight seal where refrigerant line sets penetrate exterior walls or roofing surfaces. Known as the Universal Squared model, it accommodates insulated tubing from 1.5 inches up to 3.5 inches in outside diameter, making it compatible with a wide range of residential and light commercial line set configurations. HVAC technicians use this panel to prevent water intrusion at the penetration point, reducing callbacks related to moisture damage and maintaining building envelope integrity.
This flashing panel is suited for new construction and retrofit installations where refrigerant line sets pass through exterior walls, siding, or low-slope roofing assemblies. The squared panel format integrates with standard siding and flat surface applications. It is particularly useful on jobs where line set insulation diameters vary, since the 1.5-inch to 3.5-inch range covers most residential split-system and mini-split installations without requiring multiple panel sizes on the truck.
Designed as an OEM-style flashing solution for AC line set penetrations where insulated tubing measures between 1.5 inches and 3.5 inches in outside diameter, typical of residential and light commercial split-system installations.
Installation is typically performed by licensed HVAC technicians as part of the line set rough-in process. Shut off all electrical power to the system before working near the penetration opening. Follow local building codes and manufacturer guidelines for flashing integration with exterior cladding or roofing materials to ensure a durable, watertight seal. Do not compress or deform the flashing collar beyond the rated tubing diameter range.
