The answer is No. You cannot use the YETI bottle cap on the RTIC bottle because they don’t fit properly. The YETI bottle caps screw inside the bottle, while the RTIC caps screw on the outside. Moreover, newer RTIC bottles have a wider mouthpiece or different threading, making them non-interchangeable. Even if the YETI and RTIC bottles have the same ounce capacity, do not interchange caps due to slight variations in rim width and thread pitch.
Are RTIC and YETI lids interchangeable?
No, RTIC and YETI lids are not directly interchangeable due to slight size differences. YETI lids measure approximately 3-3/4 inches at the mouth, while newer RTIC tumblers (with the Polar Bear logo) have a wider 3-7/8 inch opening—making YETI lids about a quarter inch too small to fit correctly.
However, old-style RTIC tumblers made before 2016 have dimensions similar to YETI Ramblers so that those lids can be swapped between both brands. Third-party universal lids sold on Amazon and Walmart are designed to fit both YETI and RTIC tumblers, giving you a reliable workaround if you need cross-compatibility.
Do Yeti lids fit other bottles?
Yes, Yeti lids fit several other tumbler brands that share similar dimensions. Ozark Trail tumblers are the most compatible—their 20oz and 30oz sizes use nearly identical measurements to Yeti Ramblers, so lids swap easily between both brands. Old-style RTIC tumblers made before 2016 also work with Yeti lids, since they were designed with the same specs.
However, Yeti lids won’t fit every bottle on the market. Newer RTIC tumblers with the Polar Bear logo have a wider mouth opening, and Hydro Flask bottles use a different threading that prevents cross-compatibility. If you need a universal option, third-party replacement lids sold on Amazon are designed to fit Yeti, Ozark Trail, and older RTIC tumblers.
Are all tumbler lids the same size?
No, tumbler lids are not the same size—they vary significantly by brand, model, and even production year. A 20-oz tumbler typically has a lid with an inner diameter of around 3.2 inches, while 30-oz tumblers range from 3.65 to 3.74 inches, depending on the manufacturer. Skinny tumblers use completely different lids measuring around 2.73-2.75 inches, which won’t fit standard tumblers at all.
Even tumblers with the same capacity can have different lid sizes. For example, newer RTIC tumblers have wider openings than older models, making their lids incompatible with Yeti despite both being 30oz. Always measure your tumbler’s inner diameter before buying replacement lids—a difference of just 0.1 inches can mean the lid won’t seal properly or will be too loose to stay on.
What is the diameter of a Yeti lid?
The diameter of a Yeti lid depends on the tumbler size. For the 20-oz Yeti Rambler, the lid has an inner diameter of 3.15 to 3.2 inches and an outer diameter of approximately 3.5 inches. The 30oz Yeti Rambler uses a larger lid with an inner diameter of 3.7 to 3.74 inches and an outer diameter of around 3.94 inches.
Yeti organizes their MagSlider lids into three size categories: small fits the 10oz tumbler and wine tumbler, medium fits the 20oz tumbler and 10oz lowball, and large fits the 30oz tumbler and 14oz mug. Knowing these exact measurements matters when buying replacement lids—even a 0.1-inch difference can mean a lid that’s too loose or won’t seal properly on your cup.
Are RTIC and Yeti the same?
No, RTIC and Yeti are not the same company—they are entirely separate brands founded by different people. Yeti was founded in 2006 in Austin, Texas, by brothers Ryan and Roy Seiders, while RTIC launched in 2015 in Cypress, Texas, by brothers John and Jim Jacobsen. Yeti actually sued RTIC in 2015 for copying its designs, and the case settled in 2017 after RTIC paid damages and agreed to redesign its products.
The most significant differences center on price and manufacturing. RTIC products typically cost 30-50% less than comparable Yeti items—a 20oz RTIC tumbler runs about $15 versus $30 for a Yeti—because RTIC manufactures in China and sells directly to consumers. At the same time, Yeti produces some products in the USA and sells them through retailers.
Does the Yeti 26 oz fit in a cupholder?
No, the Yeti 26 oz bottle does not fit in most standard car cupholders. The bottle has a diameter of approximately 3.5 inches, while typical vehicle cupholders measure around 3 inches wide—making the Yeti about half an inch too large for a secure fit.
Yeti’s own website acknowledges this, stating that their bottles “may be too big for most cupholders” and recommending their tumblers as cupholder-compatible alternatives.
That said, results vary depending on your specific vehicle. Some owners report the 26 oz fits loosely in trucks and SUVs with oversized cupholders like certain Jeep Wranglers and Ford F-150s, while compact cars like Honda Pilots and Subaru Crosstreks won’t accommodate it at all.
If cupholder fit is a priority, consider the Yeti 18 oz bottle at 3 inches in diameter, or purchase a cupholder adapter from retailers like Etsy or Amazon that expands your existing holder.
How do I know my bottle cap size?
Measure the inside diameter of your cap from one inner wall straight across to the opposite inner wall using a millimetre ruler. This measurement gives you the first number in standard cap sizing (like the “28” in 28-410), which must match your bottle’s outer thread diameter for a proper seal.
Cap sizes use two numbers: the first is the diameter in millimetres, and the second indicates the thread style based on industry standards set by the Glass Packaging Institute. You can also print a free cap gauge from packaging suppliers online or compare your bottle neck against common U.S. coins if you don’t have a metric ruler handy.
Why does a YETI lid have a magnet?
The magnet in a YETI lid creates a smooth sliding mechanism that opens and closes the drinking hole, helping prevent splashes and keeping debris out of your beverage. This magnetic slider also adds an extra barrier, helping retain your drink’s temperature longer by reducing heat or cold from escaping through the opening.
YETI’s MagSlider design offers a significant practical advantage: the magnet pops out easily for thorough cleaning, unlike traditional plastic sliders. The removable magnet is also dishwasher-safe and can be swapped with colored replacements, letting you personalize your tumbler or prevent drink mix-ups when multiple people use similar cups.
How big is a 42 oz YETI?
The 42 oz YETI Rambler Straw Mug measures 5.2 inches wide by 10.8 inches tall and weighs about 1.7 pounds. Despite its large capacity, it’s designed to fit in standard cup holders with a minimum 3-inch diameter opening.
This mug holds roughly 1.2 litres of liquid, making it YETI’s largest straw mug option for all-day hydration. The elevated easy-grip handle and cupholder-compatible base make it practical for road trips, gym sessions, and long workdays without constant refills.
Are YETI bottle tops interchangeable?
Yes, all Rambler bottles are compatible with YETI’s complete line of bottle caps, including the Chug Cap, Straw Cap, HotShot Cap, and MagDock Cap. The 12, 18, 26, 36, 46, and 64 oz Rambler bottles all share the same thread design, making their caps fully interchangeable across the entire range.
Keep in mind that bottle caps and tumbler lids are two separate systems—MagSlider and Straw Lids designed for mugs and tumblers are not compatible with Rambler Bottles. Yonder Chug Caps are also specifically designed for Yonder products only and won’t fit Rambler Bottles or other YETI drinkware.
Can you buy replacement lids for YETI tumblers?
Yes, you can purchase a replacement magnet, straw, or entire cap directly from YETI’s website. YETI sells replacement MagSlider lids starting at $10, StrongHold lids for $13, and straw lids and other accessories through its official drinkware accessories section.
Beyond YETI’s official store, replacement lids are widely available at retailers like Dick’s Sporting Goods, Walmart, Amazon, and eBay. Third-party compatible lids often cost less and come in multi-packs, though official YETI lids guarantee the exact fit and quality designed for your specific tumbler size.
How to measure tumbler lid size?
Use a ruler or calliper to measure the inside diameter of your cup’s opening from one inner edge straight across to the opposite side. For lids, measure across the widest part of the lid to find the outer diameter, then compare both measurements to ensure a snug fit.
Standard tumbler lid sizes follow familiar patterns: 20oz tumblers typically have a 3.5-inch lid diameter, while 30oz tumblers use a 4-inch lid diameter. The inside diameter of the lid is measured at the rubber ring on both sides, not the bottom plastic edge, so always double-check both dimensions before buying a replacement.
Do Yeti Lids fit Stanley?
Yeti lids generally do not fit Stanley tumblers because of differences in size and design; they are designed for Yeti cups. Stanley tumblers have unique dimensions and threading that prevent a secure seal with Yeti lids, making them incompatible without modifications.
Both brands use proprietary lid designs to ensure a tight fit and insulation performance. For the best experience, it’s recommended to use lids made for each brand to avoid leaks and maintain temperature control.
Can I change the lid on my Yeti?
Yes, you can change the lid on your Yeti tumbler, but it’s essential to use lids designed specifically for Yeti products to ensure a proper fit. Different Yeti models often require different lid types, so matching the lid size and style is key for maintaining insulation and preventing leaks.
Using non-Yeti or incompatible lids may cause poor sealing and affect performance. For best results, purchase replacement or upgrade lids directly from Yeti or trusted retailers to keep your tumbler working as intended.
Can you put a beer bottle in a Yeti?
Yes, you can put a standard 12-oz beer bottle inside most Yeti tumblers or coolers, but it depends on the specific model and size. Smaller Yeti tumblers may not fit a whole bottle, while larger coolers and Rambler bottles are designed to hold bottles comfortably.
Yeti products offer excellent insulation, keeping your beer cold for hours when stored inside. For best results, check the dimensions of your Yeti model and the beer bottle to ensure a proper fit without risking breakage or spillage.
Are RTIC and Yeti made in the same factory?
RTIC and Yeti are not made in the same factory, but both brands use similar manufacturing processes and materials, often sourced from factories in China. While Yeti is known for its premium quality and higher price point, RTIC offers comparable products at a budget-friendly price, leading to speculation about shared production facilities.
The key difference lies in brand ownership and design control, with Yeti investing more in innovation and durability testing. RTIC focuses on competitive pricing and direct-to-consumer sales, leveraging manufacturing partnerships that may overlap with Yeti’s but remain independent operations.
Conclusion
In conclusion, while YETI and RTIC water bottle lids often look strikingly similar and share the same general threading style across many popular sizes (especially the 18 oz, 26 oz, 36 oz, and 64 oz bottles), they are not universally identical or guaranteed to be 100% interchangeable.
Most RTIC lids will physically screw onto YETI Ramblers and vice versa without leaking in day-to-day use. Still, differences in thread depth, gasket design, and manufacturing tolerances mean some combinations can result in minor leaks, loose fits, or difficulty screwing the lid on fully.
