Measurement and customization - Measure the length and width of your original refrigerator door seal in centimeters before purchase. - Take a photo showing your seal type and groove/rail. - We manufacture seamless refrigerator door seal frames based on the information you provide to ensure a perfect seal. Sealing performance - Our seals help prevent warm air from entering the fridge, improving energy efficiency and reducing the risk of mould from faulty seals. Magnet polarity and closing force - The magnet closing force (polarity) may not be available immediately and can take up to 24 hours. - If the magnet does not stick right away, place a heavy object (e.g., a bucket of water) against the closed door to increase pressure until it adheres. Installation and shipping - To facilitate transport, the large seal is shipped folded but remains very flexible. - To install, soak the seal in hot water at 60-70 C for a few minutes, then follow the included installation instructions to fit normally. Use scenarios - Replacing a worn door seal on a home refrigerator to stop cold air loss and reduce energy costs. - Restoring a side-by-side or French-door fridge where a seamless seal improves door performance and temperature stability. - Reconditioning a commercial under-counter fridge or beverage cooler to minimize warm air intrusion and maintain consistent temperatures.
