HVAC Wall Penetration and Duct Kit Cover---for Indoor and Outdoor Air Conditioning Systems

As a part-time HVAC handyman, I buy these wall penetration kits for every customer’s mini split installation jobs. Homeowners love the neat finished look it creates, covering unsightly exposed pipe holes completely. The two-piece split design is super convenient for retrofits where the AC line is already run through the wall. The weatherproof ABS holds up great on coastal homes with constant sun and salt air, no fading or brittle cracking even after years. I always suggest the full insulated cover bundle to clients for long-term pipe protection.

I only needed a replacement sealing plate for my existing AC pipe cover, so I picked the single plate option to save cost. The material feels much thicker and sturdier than the cheap original plastic piece that cracked after two years. The elastic rubber seal sits flat against my concrete block wall, stopping cold wind from blowing inside the house in winter. Mounting screws are included in the package, the pre-drilled holes line up perfectly for easy attachment. It fits my standard 1-3/4 inch line set without any trimming or cutting required.

I installed a new mini split AC last month and the bare pipe hole on my siding looked ugly and let bugs crawl into the wall. I ordered the full kit with sealing plate and insulated cover, and it fixed all my issues at once. The UV-resistant white ABS matches my house exterior trim perfectly, the rubber gasket seals every tiny gap so no more rain leaks after heavy storms. Assembly took me only 6 minutes with a screwdriver, no HVAC contractor needed. The insulated sleeve protects my refrigerant line insulation from sun rot, I highly recommend this full bundle for any split AC install.
