Is this sport cap 3.0 leak proof? I'm replacing the standard loop cap on the 40 oz. which has been good to me so far.

I would say its about 95% leak-proof when the nipple is pressed down; I haven't had any issues so far, even with it bouncing around on my pack. On their website they call it 'leak-resistant'.

I'd agree -- I'd say 3.0 is about 95% leak proof, where the previous version (2.0?) was about 50% leak proof, and totally unreliable if the Kanteen was on its side. This one has been tipped over a batch of times in my briefcase without leaking.

No, Mine seals tight, I would return it. There is a small seal between the loop and the straw. I shake mine to mix my splenda and it doesn't leak at all.

If the lid is tight, it does not leak. I use the Camelback Chute top (I swapped it out on this bottle), not this bite valve top, so I can't speak to whether or not the bite valve leaks, but I've used camelbak bite valves in the past and they don't leak.

if the cap is screwed on completely no it will not. It is a sport top and thus if not pressed down completely it can leak then also. This bottle is built tougher than most of its type so the sport top may be a little difficult for them to press down all the way at first but it breaks in quickly and should not be an issue after that. Please keep in mind that from my experience in Houston that without ice this bottle will keep liquid cold (close to its original temperature) for 90 minutes to 2 hours at best. The platinum style bottle does a little better because its bag is more reflective. this one however is easier to spot and harder to lose. if the cap is screwed on completely no it will not.

So far the seal has been excellent. I had an occasion recently where gnats had gotten into the red wine vinegar bottle so I had to wash the bottle and the spout in the dishwasher. I've since refilled it twice and been using it with no spillage or leaks at all. The rubber stays very well and I haven't experienced any issues.

It seems to snap in to the cap very securely. I haven't had any issues with that.

I bought the 24 oz unit, and the cap is very stout, and scews in tightly, and has a rubber gasketl for a leak proof seal.

Yes they are leakproof. We've never had a problem. I carry one in my purse. HOWEVER, folks are right about the caps. a few of mine are starting to crack, possibly from over tightening. I'm going to get replacements caps because the bottles are excellent.

No its just a cap but when tightly sealed, I've never had problems of leaking when it falls over.

Absolutely. When you push the cap down after drinking, you hear a snap. Then it has a wire connector that slips over the opening also. Mine has not leaked a bit, and I have carried it in my backpack and in my huge travel purse with no problems. I love mine! I hope this helps. :)

The cap and loop are plastic, albiet very durable plastic. I keep this in a patrol car and as you can imagine it gets knocked around alot. The cap is not lined with stainless steel but the bottle is. (double walled stainless inside). The Klean Kanteen should fit the threading is similar. My only concern with switching caps would be losing the outter lip on the Life Line bottle (it covers the outside flush) sealing the exterior portion where your mouth would be if you drank straight from the canteen.

Yes, mine has a pin hole in the cap and mine does not leak. Maybe yours is faulty

Hello Mine was leaking also after a few years. This one has an "O" ring at the top. Since replacing my old one with this one I have not had any leaks at all.

The cap actually "screws" on to the top of the cup. Nothing spills out. There are grooves inside the cup and on the cap. The inside of the lens (cup) is stainless steel. the cap is plastic and has an o-ring to seal properly. The cap is actually clear on the top. No rubber in/on the cap (only the o-ring is rubber-from what I can tell). Hope that helps. - rdk

I've used it twice and haven't found issues with leaking. I seal firmly without having it overtightened as to not risk cracking the edges and it works great. The package comes with two O-rings but instructions are to just use one for the spigot and use the other as a replacement.

I have two of the 8-oz and one of the 40-oz of these bottles and none leak. All the lids have rubber gaskets on them. I use the small ones in my daughter's lunch box. It looks like they've changed the lid design since I bought mine about 2 years ago. I can say that I've found the quality of their bottles to be excellent.

I have not had an issue with leaking yet. Have been using one for about a two weeks so sorry will know more in a month or so.
