2 Sets of Thermos Stainless King (TM) -Compatible 16 Ounce Travel Tumbler/Mug Gaskets/Seals by Maplefield Products – BPA-/Phthalate-/Latex-Free – 2 Full Replacements Per Kit

I was very happy to find this product so that I could fix my old Thermos that I have had for years. However…. before I figured it out, I was greatly disappointed because I had the same issue so many here have outlined, whereas the flow just dribbled out when the top was in the open position after this kit was installed. I have seen various remedies which includes modifications, etc. However… before you go nuts… TRY THIS:The small, round, cylindrical part of the kit that goes around the center shaft of the cap is DIRECTIONAL! Meaning that the part has an upside, and a downside, and it needs to be installed in the right direction for the cap to work. If you look at this part carefully, you will see that it has a small lip that runs around the inside perimeter at one end. The end with the internal lip, faces down when installed. This keeps the item in place and allows it to push the valve of the cap open when you flip the lever to the “open” position. If you install it upside down… this part will just slide down the shaft and will not apply the proper pressure to open the valve (resulting in the reduced flow of liquid).I’m sure this explains why the mixed reviews. Some people say the kit works great, some say it doesn’t… depends if you got it right or not. It’s a 50/50 shot and the kit does not come with instructions. If you are having issues with poor flow, this is the part to look at.
