If you're installing a mini split AC or heat pump, the Daisypower Wall Sleeve is a must-have accessory to keep your line sets protected and your exterior wall looking tidy.

I recently used this sleeve when installing a new heat pump with 3/4" and 3/8" insulated lines. The fit was snug (which is exactly what you want for wall penetrations), though I'll admit it was a bit of a tight squeeze with the thick insulation. But that tight fit means better protection against pests and weather.

The UV-resistant PVC construction feels durable, and I appreciate that it comes with all the necessary accessories: decorative cap, putty, and tape. The smooth interior protects your lines from scratches - no more worrying about damaged insulation!

At 8 inches long, it's perfect for standard walls, but can be cut if needed. Installation was straightforward - just drill your hole, slide this through, feed your lines, and seal it up. The end result looks so much cleaner than exposed lines!

My only minor complaint is that the opening could be slightly larger to accommodate very thick insulation more easily. But given how well it keeps out pests and maintains my home's exterior appearance, I'd definitely buy this again.
