The Airex Titan Outlet features an enclosure with weatherproofing capabilities that fits over and seals around piping penetrations using elastomeric gaskets and seals. The manufacturer claims its product prevents the wall gaps and exterior surface cracks associated with rigid wall penetration sleeves or rigid penetration flashing materials. An integral, over-molded, and flexible elastomeric sleeve seals refrigerant piping and insulation and includes a designated region for a stainless steel clamp that mechanically secures against vibration, rodents, and insects for outdoor use. airexmfg.com
