    What does the chaff plug do?

    The chaff plug seals the base of the chaff collector and prevents debris from falling out during the roast. After roasting, it can be removed to release the collected chaff for disposal. A secure plug helps maintain clean airflow and keeps the roaster operating efficiently.

    What’s included in this replacement set?

    The set includes everything you need to replace the original chaff plug: a silicone plug, washers for proper sealing, and the screws to fix it in place. It’s a full replacement, whether your current one is damaged, missing, or worn.

    Is this compatible with all Bullet models?

    Yes – it fits all versions of the Aillio Bullet, including the R1, R1 V2, R2, and R2 Pro. The design is consistent across models and installs easily in the existing slot.

      As a R1 V2 owner with 400 (350g roasts) under the belt, I am envious of the new functionality of the R2; larger capacity, more energy efficient, easier to clean and maintain and stirrer in the drop tray.

      I've had my Bullet v2 since December of 2020, back when stock was limited and I had to pounce on the buy button when they became available. Now, after all that time, I wouldn't hesitate to buy it again tomorrow if I had to

      I believe it the best 1KG roaster you can buy.

    Frequent Questions

    What material is the plug made from?

    It’s made from temperature-stable silicone rubber, designed to handle the heat of regular roasting without warping or cracking.

    How do I know when to replace it?

    If the plug is loose, cracked, or no longer forming a tight seal, it’s time to swap it out. A good seal helps keep airflow and chaff management consistent.

    Is this difficult to install?

    Not at all. Just remove the old plug and secure the new one using the provided washers and screws.

    Is this the same chaff plug that comes with the roaster?

    Yes – this is a direct replacement for the original part supplied with all compatible Aillio Bullet models

    Can I continue roasting if the plug is damaged

    We don’t recommend it. A damaged or missing chaff plug can cause airflow issues, mess during roasting, or even compromise roast consistency. Replacing it helps keep everything running as it should.
