Sippy Cap Maintenance Kit

Customers appreciate being able to purchase replacement parts separately, extending bottle life and reducing waste. The kit fits perfectly and effectively prevents leaks. However, many customers requested selling inserts/gaskets separately from caps, as they don't need the lid. Some noted silicone pieces can hold odors if not cleaned immediately.
- Excellent little maintenance kit to revitalize a well loved bottle.
- I love that we can purchase replacement parts, extending the life of our bottles.
- Fit perfect. Had this cup for 10 years. Love it.

I’m so glad they started selling these pieces separately. We use to have to buy the whole cap so this is so nice! These will inevitably get dirty or worn down and the new ones fit perfect. They do tend to hold a nasty smell if you don’t clean bottles almost immediately after use, so we’ve started to just use the bottles for water only and the issue is resolved.

Fit perfect. Needed a new one only because old one lost. Had this cup for 10 years. Love it.

So glad they finally started selling replacement parts, especially these sippy inserts, but why the heck do you include the clear lid and raise the price?? Please sell a 3-5 pack of the sippy silicone inserts and don't include the lid to save cost. . . . we toss those immediately anyway.

These work great. I love that we can purchase replacement parts, therefore extending the life of our bottles & minimizing waste. However, I wish the caps and the membranes could be purchased separately because we definitely did not need new caps.

Really silly that the gasket isn't being sold separately from the cap cover. Would've loved a multi pack of the gasket.

It would be better if you could order caps and stoppers separately.

Excellent little maintenance kit to revitalize a well loved KK bottle. We lost our silicone insert that was preventing leaks, so it was great to once again be leak free.

Love the bottles for my 2 year old, have had it for a year. But it needed new valves.

Wear happens. I’m very thankful that Klean Kanteen offers the maintenance kit primarily for the inner replacement piece which is what I specifically needed. Cheaper than buying a whole new sippy cap. I found my inner pieces suffered more wear in the dish washer after being a religious hand washed for 8yrs. My handicap 11yr old needs a sippy cap like my toddler, it was great to be able to buy the replacement piece for all their sippy caps. So few companies offer replacement pieces like this so I found it exceptionally considerate and waste reducing for replacement pieces to be offered.
