Quickflash acu-b Ac Line Set Flashing Panel

Product Description

The QUICKFLASH acu-b is an AC line set flashing panel designed to weatherproof the wall penetration where refrigerant line sets, electrical conduit, or other service lines exit a structure. It creates a watertight seal around line set pass-throughs on residential and light commercial buildings, preventing water intrusion at one of the most common leak points in an exterior wall assembly. HVAC technicians install this panel during new equipment installation or as a retrofit upgrade when an existing penetration shows signs of water damage or inadequate sealing.

This flashing panel is suited for use on standard exterior wall surfaces where a mini-split, central AC, or heat pump line set exits the building. It is typically installed at the point where refrigerant lines, communication wire, and condensate drain tubing pass through the wall to the outdoor condensing unit. The panel covers the opening and provides a finished, weather-resistant appearance while maintaining a functional seal against wind-driven rain.

Key Features

• Designed to seal and cover AC line set wall penetrations against water intrusion
• Suitable for new installations and retrofit applications on existing exterior walls
• Accommodates typical line set bundles including refrigerant lines, electrical, and drain tubing
• Provides a finished exterior appearance at the wall penetration point

Compatibility

Designed as an OEM-style flashing solution for residential and light commercial AC line set wall penetrations.

Installation Notes

Installation is performed by a licensed HVAC technician as part of line set routing during equipment installation or service. Power to the indoor and outdoor units should be disconnected before working near the penetration area. The panel should be installed in accordance with local building codes and manufacturer guidelines to ensure a proper weathertight seal. Use appropriate exterior-grade sealant around the panel perimeter as required by local construction standards.
