This valve is made from a slightly harder silicone than the original valve and has a wider lip edge to prevent these from coming loose. To assist in inserting this, please watch this instructional video about this replacement here.
Replacement Sipper Lid Air Valve
Love, love, love it. Arrived exactly what I was hoping for.
The ice pack comes home from school still frozen and everything in my son’s lunch box is still cool. Even on a hot summer school day with his school bag outside. Would absolutely recommend!
Originally purchased because we wanted a metal water bottle so that he wouldn’t drink out of ours and it’s definitely worked! He’s obsessed and drinks so much more water now. Also a breeze to clean!
