Learn how to replace the OctaLock lid on your BrüMate Müv 15oz, Müv 25oz, or Nav 25oz tumbler with these simple steps, plus tips for choosing a matching color.
Quick Answer
To replace the OctaLock lid on your BrüMate Müv 15oz, Müv 25oz, or Nav 25oz tumbler, simply remove the old lid, align the new lid's tab with the tumbler's notch, and press down until you hear a click. Choose a Sage or Rose Taupe replacement lid to refresh your setup.
Why Replace Your OctaLock Lid?
Over time, the seal on your tumbler lid can wear out, or you might just want a new color to match your style. The OctaLock lid is designed for a secure, leak-resistant fit, so replacing it with a compatible one keeps your drinkware performing at its best.
The Müv + Nav OctaLock Replacement Lid fits three popular BrüMate tumblers: Müv 15oz, Müv 25oz, and Nav 25oz. This means you can mix and match colors across your collection without buying a whole new tumbler.
Choosing the Right Color
BrüMate offers the OctaLock replacement lid in several colors, including Sage and Rose Taupe. Sage adds a fresh, stylish touch, while Rose Taupe lets you personalize your setup. Pick the one that best matches your tumbler or your mood—it's a simple way to make your drinkware feel new again.
Step-by-Step Lid Replacement
- Remove the old lid: Twist the old OctaLock lid counterclockwise until it releases, then lift it off the tumbler. If it's stuck, run warm water over the lid for a few seconds to loosen the seal. Don't force the lid off—this could damage the tumbler rim.
- Clean the tumbler rim: Wipe the rim of your tumbler with a damp cloth to remove any residue or debris that could affect the seal. A clean rim ensures a better seal and prevents leaks.
- Align the new lid: Position the new OctaLock lid over the tumbler, aligning the tab on the lid with the notch on the rim. The lid should sit flush before you press down. Misalignment is the most common mistake—double-check before pressing.
- Press down and twist: Press the lid down firmly and twist it clockwise until it clicks into place. The OctaLock design secures the lid with a satisfying click. If you don't hear a click, the lid isn't fully locked—try again.
- Test the seal: Fill your tumbler with water, close the drinking spout, and turn it upside down for a few seconds to check for leaks. If water escapes, repeat the alignment and locking steps. A quick leak test saves you from a messy bag later.
