17pcs Water Bottle Lid Replacement for Thermoflask 24/32/40/64oz, Water Bottle Gasket Replacement Accessories Part O Ring Silicone Seal Ring Compatible with Thermoflask Spout Lid

Had a few bottles that the silicone was missing or dirty. Tool made it easy to remove the old seal and new one was easy to put in.

Was glad to have found this package at a Good price. These pieces are almost guaranteed to need replacing sooner or later so nice to have them on hand.Fit my ThermoFlask perfectly. And the included tweezers helps.

Work great but the loops on pour spout twist when turning cap.

Bought this to replace silicone seals for our existing water bottles. The original ones had mold growing on them and looked unhealthy and possibly toxic. I soaked them in every solution I could think of to remove the mold but non worked. The new seals are the exact fit and comes with enough replacement seals that we can use them to replace any seal that gets moldy. We now remove the seals after every use and dry it out before reinstalling them.

These fit the thermoflask 40oz perfectly. Very tight seal, doesn’t leak.I use the bottle all day every day, with time I will see how they hold up.

Does NOT fit all bottles listed!!!

Does what I needed it to do!

I was cleaning my water bottle and lost the gasket that keeps a tight seal on the spout. Unfortunately without it my bottle leaked. Taking a chance I ordered this replacement set and they fit perfectly. Highly recommend.
