Frequently Asked Questions
Does one sleeve fit all Air Dominion mini splits?
Yes - every wall-mounted head in the line routes its line set, control wire, and drain through a standard 3 in. penetration; capacity class does not change the sleeve.
What wall thicknesses does it cover?
4 to 7.5 in. with one sleeve; join a second sleeve for thicker walls.
Is a sleeve really necessary?
It protects the lines from abrasion at the wall edge, keeps the penetration sealed against air and pests, and leaves a serviceable pass-through for future work.
