⚙️ How COSMO Internal Plugs Work
The internal plugs are small plastic inserts that cover the holes in the bottom casing of the COSMO incubator. These holes are used for fastening during production or to house components, but must remain closed during use.
Their function is simple but important: to prevent cold air from entering from below and warm air from escaping. The COSMO incubator is designed to maintain a hermetically controlled environment, where temperature and humidity must remain constant for 21 days. Every open hole is a potential leak.
The original FIEM caps are made of heat and humidity resistant plastic, with calibrated dimensions to fit perfectly into the holes of the COSMO body.

🔍 When to replace this part
Replace the COSMO internal caps if you notice:
- ✓ Missing caps: Open holes visible in the bottom shell.
- ✓ Broken or cracked plugs: They no longer seal the hole properly.
- ✓ Caps that don't hold: they fall off or slip off easily.
- ✓ Cold drafts from below: when you bring your hand closer, you can feel the air coming in.
- ✓ Unexplained unstable temperature: after checking the control unit and resistor, check the caps.
⚠️ Why it happens and what you risk
The caps are mostly lost during cleaning or when the incubator is disassembled for maintenance. They can also break if you force them out or if the plastic has hardened over time.
A missing cap may seem like a minor detail, but it can cause real problems: cold air entering from the bottom creates a cold zone that the heating element must compensate for, increasing fuel consumption and creating thermal instability. People often think the problem is the control unit or the sensor, when simply inspecting the caps can identify the cause.

💡 Tip: If you're unsure how many caps you need, check the bottom of your incubator and count any open holes or damaged caps. Order a few extra as a backup.
🔧 Assembly in 2 simple steps
⏱ Estimated time: 1-2 minutes | 🔧 Tools: None
- Locate open holes
Turn off the incubator and lift the top cover. Inspect the bottom cover and locate any holes with missing or damaged caps. - Insert the caps
Press the new cap into the hole until it clicks into place. Make sure it's secure and won't come off.
🛡️ How to make them last longer
- ✓ When cleaning: be careful not to remove the caps when you pass the cloth over the body.
- ✓ During maintenance: if you need to remove a cap, do so delicately without forcing it.
- ✓ Periodic check: every start of the season, check that all the caps are in place.
