40 oz Leak Proof Handle Flip Straw Lid Replacement for Stanley 40 oz Quencher H2.0 and ProTour Tumbler, Not for 30 oz Cup

This lid fit my 40oz Stanley perfect. The seal is nearly water tight, it will only berley drizzle from the nozzel if tipped upside down. If it tips over on it's side fine. Flip up straw works great. Super durable carry handle is sturdy and has a little clip for hanging on a strap or even a stroller. Also ive noticed the insulation is better than the oem lid. My ice stays ice munch longer.

Bought this in Aug 2024. I was carrying my water bottle by this handle in Feb 2025 and it completely broke off! Everything fell and made a huge mess. Ever since then the lid leaks out the edges and if I tighten it too much it comes right off. It was great for 6 months and now it is awful and barely usable.

The color is great. The lid fits well. The only downside is everyone in the room can hear you drink. I have adjusted the straw and that still didn’t help.

Cap fits wellAny adjustment to straw tip when sipping causes air to come upAnd it is not leak proof.I felt it on my passenger seat laying and as im getting out i realized so much water leaked out from the cap. Still a good product, just isnt leak proof

Wasn’t sure it was going to fit as great as it did. I bought this for my daughter’s 40oz Stanley tumbler she absolutely loves it. fits perfectly. The quality is great it’s leakproof and my favorite part is that it’s easy to open so cleaning is a breeze!!! I liked it so much a bought one for mine now I don’t have to worry about them tipping over in a bag when we’re on the go. If your a Stanley girlie run don’t walk to get one of these you need one!!

Pretty good product- for the money- The popular brand did not have any of these available (SOLD OUT) and they were 2x as much for 1 without the necessary straw.I bought these for my 40oz Quencher- which came with the typical long straws and screw down lids. Unfortunately, with the vacuum seal, once those lids are screwed on and you have all the leak points sealed with after market gaskets etc. , it is a trick getting water to come up the straw- air pressure sort of stuff here. I was tired of twisting the cap off a little each time to get air into the bottle to make straw drinking more effective.My IceFlow Jug has one of these flip top caps and the ease of drinking was a lot better than the Quencher straw system. Thankfully, these lid replacements satisfy my needs.One note: On one of the 40oz ers- the lid screwed on easily- just a little adjustment and it screwed down to a tight seal. On a second 40oz er same brand, same model- the lid was a beast of a trouble to get screwed down the right way. It finally got there, but there must be some minor difference in the screw part of the lids and it just wasn't easy. 1-STAR reduction-No leaking- at all- compared to manufacturer's straw system- even with the gaskets- those gaskets still drip a little. This product does not leak- on either bottle. I'm impressed with that. Plus there is a "fence" hook on the handle which mimics the same fence clip feature on the popular brand ice flow jug handle. It's a nice touch for outdoor work etc.I would recommend this product, but i imagine there a lot of other brands out there that do the same thing- maybe those would screw down easier and more consistently across the product line. Probably wont hurt to try a few out.

I bought 2. One for my wife one for me. The one my wife got had an air leak somewhere. Tried switching the straw and making sure it was tight. Still just leaked air couldn’t get much out of the straw. The one I got the straw would stick to the bottom of the cup so didn’t get much water from that. Other than that they didn’t leak and carrying handle was nice even though the cup already has a handle on it. But they looked good and the price was decent

Not recommended for the 40oz Protour Stanley. Will fit it, but is tough to line up and screw on.
