RectorSeal’s Outset Seal, an adjustable lineset protection system for ducted and ductless HVAC installations, is designed to protect indoor areas by blocking air leakage, moisture penetration and rodent intrusion and hiding unsightly wall penetrations where HVAC linesets enter or exit structures. The product is backed with RectorSeal’s three-year limited warranty that requires no registration. Suitable for both new and retrofit HVAC installations, the Outset Seal kit includes a 12-by-12-inch panel that will accommodate HVAC linesets up to measurements of 7/8-inch outside diameter with ¾-inch of insulation.
