Tumbler lid replacement: who sells the lid, the gasket and the straw, and how to match the size
The tumbler lasts; the lid does not. The whole buy-once question for drinkware is whether the maker sells the lid five years from now. Here is who does, what they sell, and the two ways to get the wrong one.

Matching the lid
Tumbler lids are size-specific and, within a brand, line-specific. Stanley's 40 oz FlowState lid does not fit its 30 oz, and the ProTour flip-straw lid is a different lid from the FlowState even at the same size. YETI's MagSlider for the 20 and 30 oz Ramblers is one part; the 26 oz bottle takes caps, not lids. Klean Kanteen's TKWide caps fit every TKWide bottle regardless of size, which is the design that makes its gasket kit possible. The rule: buy the lid from the maker's own accessories page, filtered by the exact model and size printed on the bottom of your tumbler, and treat “fits 40 oz” on a third-party listing as a guess.
Gaskets and straws
The gasket is the part that actually fails, and only Klean Kanteen sells it on its own as a kit on the pages we read (“two o-ring gaskets for use on any of our TKWide Caps”). Stanley's ProTour lid has a “replaceable seal,” which is the same idea built into the lid. Everyone else replaces the gasket by replacing the lid or cap, which is $10–$20 instead of $3 and is still a fraction of a new tumbler. Straws: Stanley and Simple Modern sell them and ship spares; YETI sells them; RTIC ships two and sells none. Straws split at the bend and grow film inside; how to clean a tumbler lid and straw covers keeping them, and replacing them is the plan when cleaning stops working.
Third-party lids
Copies of the FlowState and MagSlider are everywhere. Two cautions. YETI's warranty “does not cover defects caused by third-party modifications, repairs, or replacement parts,” and a Rambler is a five-year product, so a genuine lid protects the term. Stanley's term excludes lids anyway, so a third-party FlowState lid costs you nothing on paper; what it may cost is the seal, which is the reason you are replacing the lid. The buy-once move is the maker's part, from the maker's page, matched by model. The tumbler warranty comparison quotes each term's lid language; Yeti replacement parts covers YETI's catalog in full.

How we scored this
Units we claim to have tested: 0
Plenty of sites say they filled every cooler on this list with ice and watched it for a week. We don't say that, and we say so on every page. What we do instead: read the maker's published capacity, insulation, dimensions and weight; quote the warranty term from the maker's own warranty page with the date we read it; check whether the latches, gaskets, plugs, lids and straws are sold as parts; and cite the third-party ice-retention tests (OutdoorGearLab, Outdoor Life, Treeline, Outside, Gear Patrol) as their measurements, never ours. Every figure links to where it came from.
Scores are editorial judgments from that documented research, not lab results. Commissions never set a score or decide a pick. The rubric and its weights are published.
Questions
Frequently asked
Does Stanley sell replacement lids?
Yes, in a Lids collection: Quencher FlowState lids by size, ProTour and IceFlow flip-straw lids, straws and toppers. Stanley's lifetime term excludes lids, which is why it sells them.
Does Yeti sell replacement lids?
Yes: MagSlider (20 and 30 oz), Straw Lid and HotShot for Ramblers; Chug, Straw and HotShot caps for bottles; replacement straws. Genuine parts keep the 5-year term intact.
What replacement lid fits a 40 oz tumbler?
The one from the maker for that exact model: Stanley's 40 oz FlowState or ProTour lid, Simple Modern's Trek lid. Lids are line-specific, not just size-specific.
Can I buy just the gasket for a tumbler lid?
Klean Kanteen sells a TKWide gasket kit; Stanley's ProTour lid has a replaceable seal. Most other brands replace the gasket by replacing the lid.
Does a third-party lid void the warranty?
YETI's document excludes defects caused by third-party parts. Stanley excludes lids from its term regardless. Buy the maker's lid inside a term you care about.

We don't claim to have tested these coolers or tumblers and we don't pretend to. Units we claim to have tested: 0. Specs come from the maker's own product pages (linked on every product), warranty terms from the maker's warranty page with the date we read it, and ice-retention measurements are attributed to whoever made them. Amazon prices change often, so we don't print them. Where a figure isn't published, we say so. Read the full method.
