Portable AC Window Sealing Kit – Pull Cord Design for Zero Gap Seal
This air conditioner venting kit upgrades the traditional zipper design with a practical pull cord system. Tightening the cord creates a tight seal between the sealing cloth and the venting hose – achieving true "zero gaps". This locks cool air inside, prevents hot outdoor air from entering, and boosts cooling efficiency.
High-Quality Silver-Plated Fabric
The sealing cloth is made of premium fabric with a silver-plated surface. It blocks rain, dust, and outdoor elements effectively, keeping your indoor space dry. It also provides UV protection and heat insulation, helping the room cool faster, reducing energy consumption, and saving money.
Simple Installation – No Tools Required
Open the sliding window and clean the frame surface.
Measure all four sides of the window and cut the Velcro tape accordingly.
Attach the Velcro to the window frame, then apply the sealing cloth. Trim excess fabric with scissors, or roll it up and secure with clips.
Insert the venting hose through the sleeve, tighten the pull cord, and secure with the zipper.
