Diagnose a leaking Hopsulator Duo or Trio, confirm your OctaLock gasket needs replacing, and choose between the Kiwi and Primrose replacement gaskets.
Quick answer
If your OctaLock Hopsulator Duo or Trio lid leaks around the can opening, replace the OctaLock gasket with the Kiwi or Primrose version; both are genuine BrüMate replacement parts for OctaLock Hopsulator Trios, so the only real difference is color. Choose the color that matches your cooler or your preference.
Why the gasket, not the lid, is usually the culprit
The OctaLock gasket is the soft ring that seals the can opening. When it is lost, torn, or stretched, liquid escapes around the can even though the lid is locked. Before ordering a replacement, check that the lid is fully seated and the can is the right size for your Hopsulator; if the leak persists at the seal, the gasket is the likely cause.
Both the Kiwi and Primrose gaskets are listed as compatible with OctaLock Hopsulator Trios. The product pages do not list separate fitments for the Duo, so if you own a Duo, confirm your lid uses the OctaLock gasket before ordering. The color names refer to the gasket itself, not the cooler body, so pick the one that matches your setup or simply your preference.
When a new gasket won't fix the leak
A replacement gasket restores the seal only if the lid and can are undamaged. If the lid is cracked, the locking mechanism is broken, or the can itself is dented at the rim, a new gasket will not stop the leak. In those cases, stop and consider replacing the lid or the cooler instead of ordering another gasket.
Also check that you are using the correct can size for your Hopsulator model. A can that is too tall or too narrow can prevent the gasket from seating properly, which can look like a gasket failure.
Diagnose your leak in four steps
- Symptom: leak around the can opening: Liquid seeps from the seal between the can and the lid, even when the lid is locked. This points to the gasket rather than the lid threads or the can itself.
- Likely cause: worn, lost, or damaged gasket: Inspect the gasket for tears, stretching, or missing pieces. If it is damaged or absent, order a replacement OctaLock gasket in Kiwi or Primrose. If the gasket looks intact, check can size and lid seating before ordering.
- Corrective action: swap the gasket: Remove the old gasket, press the new one into the lid channel, and test with water before use. Both Kiwi and Primrose gaskets are genuine BrüMate parts for OctaLock Hopsulator Trios.
- Stop point: lid or can damage: If the leak continues after a new gasket, or you see cracks in the lid or a dented can rim, stop replacing gaskets and inspect the lid or can instead. A second gasket won't fix a cracked lid.
