Learn which replacement seal fits your AeroPress model, how to diagnose a leak, and when to replace just the seal versus the entire plunger.
Quick answer
If your AeroPress Premium leaks around the plunger, replace only the Premium Seal. If your AeroPress Go leaks and the seal is loose or worn, you can replace just the seal on your existing plunger, but the Go Plunger including seal is a complete drop-in option if you prefer not to handle the seal separately.
Why the two seals are not interchangeable
The AeroPress Premium Seal is designed specifically for the glass AeroPress Premium model. The AeroPress Go Plunger including seal is a spare plunger assembly for the AeroPress Go travel press. Because these are different models, the seals are not cross-compatible. Using the wrong seal can cause a poor fit and continued leaking.
If you are unsure which model you own, check the chamber material and overall shape. The Premium uses a glass chamber, while the Go is a compact travel press. Matching the seal to the model is the first step in any AeroPress seal replacement.
When replacing just the seal is enough
In most cases, a leaking plunger is caused by a worn or loose silicone seal, not a damaged plunger. For the AeroPress Go, the catalog notes that if your seal is loose and worn, you only need a new seal, not a new plunger. The spare seal can easily be replaced on the end of your existing plunger.
For the AeroPress Premium, the Premium Seal is the official replacement part for the plunger seal. If the plunger itself is intact, swapping the seal restores performance without buying a whole new plunger.
When to choose the complete plunger assembly
Choose the AeroPress Go Plunger including seal if you want a ready-to-use replacement or if your existing plunger shows signs of damage beyond the seal, such as cracks or a bent shaft. This assembly includes a food-grade LFGB-grade silicone rubber seal gasket and is a direct replacement for the Go.
For the Premium, no complete plunger assembly is listed in the catalog; the Premium Seal is the available replacement part. If your Premium plunger is damaged, you may need to contact the manufacturer for further options.
Diagnose your leak: symptom, cause, and action
- Symptom: leak around the plunger during pressing: Likely cause: worn or loose seal. Corrective action: For AeroPress Premium, replace with the Premium Seal. For AeroPress Go, replace just the seal on your existing plunger, or choose the Go Plunger including seal if you prefer a complete assembly. Stop here if the new seal restores a tight fit. If leaking continues after seal replacement, check for damage to the plunger or chamber.
- Symptom: seal feels loose or slides off easily: Likely cause: silicone seal has stretched or worn. Corrective action: Replace the seal. For Go, the catalog notes you only need a new seal, not a new plunger. For Premium, use the Premium Seal. A seal that no longer grips the plunger edge is due for replacement.
- Symptom: plunger is cracked, bent, or otherwise damaged: Likely cause: physical damage to the plunger. Corrective action: For AeroPress Go, replace the entire plunger with the Go Plunger including seal. For AeroPress Premium, no complete plunger assembly is listed; contact the manufacturer for options. If the plunger itself is damaged, a seal alone will not fix the leak.
