Extremely functional, fit well, made out of quality rubber the build quality is great, reasonably priced and definitely something that anyone who has a Coleman gas stove or lantern should definitely have on hand.

Changing No. 3 coleman gaskets is not a quick or easy task, but I dove in and did it to two particularly dried out gaskets that weren't holding a seal any more. These gaskets appear to be the correct diameter and thickness. The material is good. Only time will tell how the material holds up, but I think these will be just fine. I dug out the old gasket in my old fuel cap and put this new gasket in. Put the fuel cap back on, pumped to pressurize the tank and lit the lantern. It worked beautifully. Checking the next day, the tank was still pressurized, so no leaks were found. Overall, I think these are a great value, especially considering how many you get! Go ahead and replace your old, crunchy gaskets. You'll be glad you did. Oh, and watch a youtube video or two about how to change these gaskets. There's definitely a process to it.

Keep your Coleman equipment going with these fuel cap seals ! Easy to install and still have plenty for later ! Get your stove and lanterns ready for camping !

These seals will do an adequate job and provide a good seal. They come in a quantity that makes it convenient for the GPA hobbyist/enthusiast. The number two gasket seals fit only the Coleman style three piece fuel caps. The only discrepancy seen was that the diameter is slightly larger than the original (see photo). However, once in place they seal perfectly. As far as durability, time will be the test. They are a good value given the quantity received.

These seals are well made and solid yet flexible and compressible, as they should be. If they are the same seals as those in the seller's lantern caps, they are excellent. But I am having trouble judging them. They appear thicker than the ones in the actual caps and have a narrower hole in the middle based on visual inspection of the inside of the cap. These seal rings fit perfectly into the threaded portion of the cap, and the inside diameter at the top of the cap appears to be wider than that in the threads of the cap If the washer seal is intended to be stretched over the center protrusion, that would press the outer diameter of the seal outward and make these a fine fit. But that also assumes the height of the seal washer would fit into the end of the cap when stretched. Eyeballing these and looking at the height of these compared to the height of the cap seems visually to make these too thick--but, again, if they are compressed when actually fit inside the cap that is no problem.The second listing photo with the measurements shows the washer to be 0.15 thick, 0.7 wide, and 0.3 diameter center hole, which translates into 0.2 inches for the width from the inside to outer edge of the seal. I measured these with digital calipers to see if my eyeball impression was on target--I don't want to risk ruining a cap by pulling out its seal and find myself with one that is too thick, and has too small a center hole. The measurements that I got, after repeating each several times, were height .159, width of ring .20; the center opening measures .036 and the outer diameter of the seal/washer was .076.The 0.20 inches for the width of the ring matches the display measures exactly. The seal was thicker than shown in the diagram, I doubt the slightly wider outer diameter makes any difference--the seal fit perfectly into the threaded area; I needed a toothpick to remove it. The larger center hole is also a plus--the diameter of the center node of the cap is definitely larger than the center hole.So I'm still trying to figure out what is going on. I am terrible at using an iPhone to take photos, but have attached three imperfect ones. The first shows the seal and the filler cap with seal in place, and you can see that the center node inside the cap is wider than the opening in the seal--including an outer flat fringe. The second shows the cap with the new seal partly inserted--enough to show that the center hole is narrower than the protrusion at the bottom (top) of the cap). The third shows relative thickness of the seal compared to the height of the cap. This means to me that some type of narrow hook or probe may be needed to get the seal to stretch over that center protrusion, and that some pressure must be applied to get the seal to be set against the bottom portion of the cap so that a good seal will result when the cap is screwed back on.I suspect that these rings do fit with stretching and compression, but I don't want to risk removing and trying to replace the ring inside a working but worn ring. The caps on my Coleman 285 dual fuel, on the Coleman Powerhouse, on the single mantle red lamp with the ball shaped globe, that on the single burner backpack stove, and those in my small and my large two burner stoves are all interchangeable and all looked the same when taken off--though the seals of some of these show how they were compressed by the tightened cap.I am giving this a rating of four stars--based on the visual discrepancies in the size of the seals and of the center hole compared to the caps with compressed seals. The height difference, while seemingly small, and the noticeably smaller center hole, introduce the risk of making the cap nonfunctional. If the seller can indicate that these same rings are those inside the new fuel caps, that would make these a solid 5.0.
