I bought these as a replacement for a damaged O-Ring on my Nissan Thermos Travel Mug. These are perfectly suited to that task.

I bought these o-rings as a replacement on my Nissan spill proof travel mug. I use this mug all the time. It will keep a cup of freshly made tea or coffee hot for 3-4 hours if left closed, or at the right drinking temperature for a full hour. I tried to find a replacement for the o-ring at the Nissan website but could not. These o-rings are an excellent replacement. The mug closes water tight and works like new. Highly recommended for this application.

These are very strong little o-rings, with plenty of tensile strength. I read a recent DIY article online about turning certain fountain pens (Platinum Preppy line) into eye dropper fountain pens using this size o-ring. I wanted to give it a try, and I must admit it worked like a charm. No leaks, perfect. Search online for "eye dropper fountain pen" and "o-ring" or perhaps "make your own" and you should be able to find it, if you're interested. Fun, and a good use of the pen and the ink.

I bought these based on the recommendation of a previous reviewer. The seal on my Nissan 14oz Leakproof Insulated Travel Mug broke when I was washing it, and without the seal, it wasn't leakproof. These work great. Thanks, previous reviewer!

I lost the original ring to my Nissan Stainless coffee cup, and was looking for a new one on Amazon, when Amazon suggested this o-ring to me. What a good suggestion! Now my old cup has a new lease on life and I can lose the ring like 9 more times before I have to buy a whole new one :)

Ordered 8 bags and each one is shorted between 5-9 pcs. If the o-rings were more costly, I'd complain but it's more of a nuisance.

My husband takes a Thermos travel mug of coffee with him every workday, and the o-ring was very stained. I also figured that eventually it would relax and no longer provide a tight, leakproof fit. I thought finding a replacement would be impossible, but, when it looks impossible . . . try Amazon! Found these, which are the exact size as the original. We're set for a long time, now!

My favorite Nalgene 750ml bottle had turned into a "dribble" bottle. This ring is the correct size to fit over the neck and seal against the cap when the cap is screwed on. Not perfect - when you unscrew the cap, a little water that was sitting above the ring will drip. But I'm not getting dripped on when I drink.

WOW, researched "O" Rings off & online for awhile, almost bought one at another store online, but it was 5 times the price, I thought of amazon and I probably could have done even better, but I am pleased with these.

Thank you again, Amazon has not let me down yet!! NO LEAKS!
