Keep Your Favorite Tumbler Performing Like New!
Has your trusted tumbler started leaking? Don't retire your favorite cup – revive it! Our premium replacement gasket and cap kit is the eco-friendly and economical solution to restore the factory-fit seal and leak-proof function to your compatible 40oz & 30oz travel mug.
THE IDEAL FIX FOR COMMON PROBLEMS:
Leaking or Dripping Lid? → Worn-out gaskets are the #1 cause. Our seals restore the tight seal.

Lost or Damaged Straw Cap? → We include a replacement slider cap to complete the set.

Stained or Old Seal? → Renew your cup's hygiene and appearance with fresh, clean parts.

KEY BENEFITS:
Engineered for Performance: Meticulously crafted to match the exact specifications of compatible tumblers, ensuring a perfect fit that stops leaks before they start.

Your Health Comes First: We pledge that our products are made from 100% food-grade, BPA-Free materials. Your drinks will taste exactly as they should, with no plastic odor or flavor transfer.

Unbeatable Value: Why buy a whole new tumbler for $40 when you can fix the problem for a fraction of the price? Our multi-pack means you'll have spares on hand for years to come.

Sustainable Choice: Choosing to repair rather than replace reduces waste and is a win for your wallet and the planet.

COMPATIBILITY NOTE:
This product is designed to be compatible with the popular Stanley 40oz and 30oz Adventure Quencher H2.0 Flowstate Tumbler. It is a third-party replacement part and not an original manufacturer's accessory.

Please double-check your tumbler's model and size (40oz & 30oz) against your original parts and our product images to ensure a perfect match before ordering.
