Portable AC Window Seal Kit (No Hose) with Rain Cover - 4 Adjustable Panels 17" to 61", Fits LG Whynter Haier 99% Portable Air Conditioners, Airtight Sliding Window Vent Seal, Replacement Window Kit — Open-Box, 29% Off

✅ COMPLETE KIT WITH RAIN GUARD — STAY COOL EVEN ON RAINY DAYS: Everything in one box: four adjustable window seal panels (17"–61"), one 78-inch exhaust hose (5.1" or 5.9" diameter), one rain-deflecting outdoor hood, universal hose adapter, mesh guard, screws, seal tape, and installation guide. The rain guard attaches to the exterior hose outlet and diverts rainwater away from the opening — no more rushing home to pull the hose when a storm rolls in.

✅ FITS YOUR WINDOW AND YOUR AC — MEASURE ONCE, INSTALL ONCE: Seal panels adjust from 17 to 61 inches, fitting standard single-track sliding windows (horizontal or vertical). The universal adapter connects to both 5.1-inch and 5.9-inch exhaust hose diameters — the two standard sizes used by LG, Whynter, Haier, Honeywell, Black+Decker, Midea, and 99% of portable AC brands. Measure your window opening. If it falls between 17" and 61", this kit fits.

✅ THE RAIN GUARD SOLVES #1 PROBLEM: Every portable AC user knows the anxiety: you leave the house, it starts raining, water flows back through the exhaust hose and into your AC unit — causing mold, damage, and voided warranties. The included exterior rain hood creates a downward-angled deflector over the hose outlet that channels rainwater away from the opening while still allowing hot exhaust air to flow freely.

✅ RIGID PVC PANELS — BUILT FOR AN ENTIRE SUMMER: The seal panels use high-density rigid PVC that resists warping and yellowing under direct sunlight. The rain guard is constructed from UV-stabilized material with a sealed joint where it meets the hose — preventing water from seeping in at the connection point, not just at the opening. The tape along all panel edges maintains an airtight seal between the panel and your window frame throughout repeated temperature changes. No sagging, no gaps.

✅ NEED THE LONGER VERSION? + NO-HASSLE PARTS GUARANTEE: This kit covers window openings from 17" to 61". If your opening is longer than 61" — like a sliding door — see our 6-panel upgrade kit that extends to 90" and includes the same rain guard. Every kit is counted and inspected before shipping. If any component — panel, hose, rain guard, or screw — is missing or damaged on arrival, message us and we'll ship the replacement part within 3 business day. No need to return the whole kit.
