gulrear Dual Hose Portable Air Conditioner Window Kit - Seamless Seal

In this review the gulrear Dual Hose Portable Air Conditioner Window Kit is evaluated for people who need a practical replacement vent kit for dual hose portable AC units. The bottom line: it is a thoughtful, user-friendly window seal that fits windows from 25 in to 60 in and is designed specifically for dual hose units with a 5.9 in exhaust and 5.0 in intake outlet, making it the best choice for anyone replacing a worn factory kit or seeking a cleaner, gap-free installation.

Key Features

• Dual hose compatibility: Built for portable ACs with both a 5.9 in exhaust and 5.0 in intake outlet so users avoid mismatched adapters.
• Seamless card slot design: The 2023 upgrade uses embedded grooves to connect inner and outer panels, eliminating edge gaps that cause leaks in older sliding kits.
• Adjustable length: Four interlocking plates let the kit extend from 25 in to 60 in so it fits a wide range of vertical or horizontal sash windows and sliding doors.
• Oval exhaust openings: Elliptical vents reserve space and seal reliably even when the window frame has side grooves, improving fit over traditional circular cutouts.
• Complete hardware set: Includes adaptors, sealing tape and butterfly screws so installation requires no additional parts for most dual hose units.

Who It's For

This kit is best for owners of dual hose portable air conditioners that have a 5.9 in exhaust outlet and a 5.0 in intake outlet and who want a neater, more sealed install than many factory kits provide. It suits renters and homeowners who need an easy DIY solution that works with both vertical and horizontal windows and sliding doors.

It is not ideal for single hose portable ACs or for units with outlet diameters that differ from 5.9 in and 5.0 in; buyers should verify internal edge to internal edge measurements on their unit before purchasing. Those needing custom-sized or permanent-frame installations should consider professional alternatives.

Pros & Cons

Pros

• Well matched to dual hose layouts, reducing confusion during installation.
• Seamless 2023 design and oval vents provide a tighter, more reliable seal than basic sliding kits.
• Adjustable plates and included hardware make setup straightforward and flexible for many window heights.

Cons

• Some users report differing opinions on fit and perceived quality, so fit may vary with unusual window frames.
• Only compatible with specific 5.9 in/5.0 in outlet sizes, so it is not universal.
