Replacement ring seal for the Klean Kanteen.

I've had my Klean Kanteens for years but the seal grew less effective over time. It is great to be able to keep the Kanteen but replace the seal. Both bottles are no longer leaking. Thank you.

Straw cap is impossible to clean, so I don't need these

These are fine. . . Unfortunately I bought them with the idea of making the caps last longer, but once I got my order I realized that the straw caps I bought will be impossible to clean, so I will need to buy new caps if I want to keep the bottle. So I guess I didn't need the gaskets after all.

TLC for your favorite water bottle

These gaskets keep my water bottle leak-free and clean. I’ve had my oldest classic bottle for over a decade, and the only part that’s ever failed was the gasket. Being able to replace this one small part kept my favorite water bottle going for another five years (and counting!).

Keeping our little one’s KK bottle leak free!

After losing the silicone ring for our little one’s KK bottle lid, we’re leak free once again thanks to the classic cap maintenance kit. The perfect solution for keeping one more thing out of the landfill.

Yay!

Good stuff to keep my older bottles like new. The only company that easily supplies replacement o-rings.

These are exactly what they say. Gaskets came in a sealed package and fit my product.

Classics bottle cap o-ring

Fit well. Glad I could just get the o-ring.

Not a kit.

This isn't a kit, it's two replacement gaskets/rings, no tool. Very tricky to get the old gasket out and get the new one into place but it works good.

Nice to have o-rings!

Good to have some spare o-rings just in case.

Package issue

I like that I get to replace the ring from the maintenance kit. However, when I received the package, it looked like there were no sealed package for them and they were all over the place in the box. Thus, I gave it two stars simply because of the package. Maybe an email from the company to explain the low inventory of the item can be very helpful before shipping the item to customers.

The little gasket that could

I've had this plain green 27oz bottle for several years. The gasket started growing something black, on it and into the silicone. So I had to ditch it in favor of this new gasket. Easy peasy.

Bet you didn't know your bottle can make this sound!

Kit as described bottle design leaks

The classic cap maintenance kit was just as expected and very easy to use. My only issue is that both bottles still leak a little after replacing all the parts. I guess that’s how the bottle was made and meant to be. Slightly disappointed as I would love a kids bottle that didn’t leak!

Kit is a great replacement

Kit is a great replacement alternative to buying an entire new cap. Fit is great for classic insulated bottle gaskets.

Extends the life of a cap

After years of using our caps, we could no longer get the rings clean.
So glad to have these replacements! Caps now work like new.

It works as intended. Not

It works as intended. Not much more to say than that truly. It's a plastic ring that replaced the old one.

Just what I needed

I've had my stainless steel container for a decade and noticed that it had developed a bit of a leak. I was prepared to buy a new cap but was relieved to see that new gaskets, which is what I knew I needed, were available and didn't require a talk with an agent. It was easily exchanged. I'm thrilled to be able to extend the use of my plastic cap.
