I want to take fish home in cold seawater without worrying about water leakage from the cooler, so I replaced the general-purpose packing and am selling the remaining 4+ meters in cut lengths. For Daiwa Mini Cool S, GU 850, and 650: Groove width 6.5mm, length approx. 81cm ● The lids of S850 and GU650 have the same shape, and both can be replaced. For 1050 and 1250, I think the groove width (thickness) is the same, but the packing is a little longer. Please measure the circumference and groove width before removing the packing and consult with me. ● At a minimum, remove the old packing and adhesive up to the point shown in image 3. If a thin layer of urethane remains on the adhesive surface (less than 1mm), there should be no problem installing the new packing. ● Since this is a thicker and more resilient silicone packing than the original, the lid became a little harder to close after replacement. At first, you need to apply firm pressure from above to lock it. Leave the lid closed for at least 4-6 days or more to allow it to settle. ● I think it can be used for Daiwa cooler boxes other than Mini Cool if the groove width is 6.5-7mm, but please purchase at your own discretion and responsibility. Cool Line and other similar packing are also likely compatible. minicool S GU 6.5L 8.5L 10.5L 12.5L Daiwa Light Game Cooler Box Eging Ajiing Mebaring Onishime
