Air-Sealing an HVAC Line Set
The Airex wall entry things http://www.airexmfg.com/titan/ look useful for air sealing HVAC lineset entry.
However all their documentation shows linesets with round insulation (or where one line isn’t insulated at all. minisplit linesets are both insulated and stuck together, forming more of a “figure 8” shape.
I’m confused whether/how the Airex Titan round shape can seal around these lines. Their tech support number just said, “cinch it down real tight”.
Anyone got any experience with that? Feels like you’d never cinch a circle down to really seal against the figure 8 lineset. Maybe everything just crushes down and the lineset insulation re-expands enough?
