Awesome. It's a little thicker than the original one but my original one could have shrunk over the 16 years. Fits 2007 Matrix gas cap.

Corolla check engine light came on, scanned for the code, and found system leak. Checked the gas cap and it was loose and the 17 year old gasket was degraded. Replaced it with this one and problem solved. The gas cap fits tighter and the check engine light is off.

5.0 out of 5 stars Cleared my evap code
Reviewed in the United States on April 2, 2024

Worked just fine to clear the evap code on my 2016 Camry. I've waited a month before posting a review just to make sure that the code didn't come back. At first I was going to buy the whole gas cap but decided to take a chance on just buying the o-ring, glad I did as it saved me a few bucks and solved the problem.

5.0 out of 5 stars Easier than a children's wobbly donut spike! Fixed engine code, low cost and good quality.
Reviewed in the United States on April 21, 2019

Update: 8 months later the P0440 on my V8 Lexus came back... but I've been driving it really hard, and there's been a lot of rain lately. This is so inexpensive and easy, I'm going to get another, and I'm confident that's the right choice.

Original from April 2019- LOVE THIS. I love DIY anything, but I also have using plastic unnecessarily, especially if it can't be recycled. This slipped on to the stock OEM gas cap (with tether) of my Lexus SC430 / Toyota Soarer beautifully replacing the old ring which had a visible crack and was causing a check engine light, p0456 if I recall, the same code this ring has fixed for others with V8 Toyota / Lexus motors. I love how little waste there was, the fit is great, rubber quality was pretty good. I could only be happier if they used an advanced poly compound silicone, but really this is pretty darn good, especially for the price. For LESS than 25% what the dealer charges for a new setup, before having to install and figure it the tether, you can have this. I used a soft spudger (lol look them up, def worth the $3) but any sturdy flat soft plastic tool should be able to get the old ring off easily without making your hands smell like old dinosaurs. Install is easier than that kids toy with the colored rings / donuts you impale on a wobbly spike.

Fits perfectly for my 03 Toyota Echo. Don't even need to go past the first click for now. These gaskets will shrink over time. The original lasted 20yrs, needed 2 clicks to tighten. Hope this one lasts as long.

Had a stubborn EVAP code on our Rav4 - P0442 (small EVAP leak). The gas cap itself looked fine ($30 OEM) but the gasket was visibly dried up and compacted. Put this new gasket on with a little lubricant, reset the codes, and 8 months later the code is still off! Success!

Turns out I had a split seal and this item did the trick. No more raw fuel odour coming from the gas cap and the CEL is gone. Replacing this item was a breeze and then I just cleared the code with my reader. Ezpz. Will buy again if I have another cracked rubber seal.
