How to Properly Fill Your CBS Pen (Step-By-Step Guide)
Step 1: Pre-Heat Your Oil (But Don’t Overheat It)
For smooth, consistent filling, gently warm your oil before dispensing it into the pen.
✔ Recommended oil temperature: Warm, but never higher than 122°F (50°C).
Why this matters:
- Keeps your terpenes intact
- Helps your oil flow evenly
-
Prevents oversaturation or wicking issues
Step 2: Use the Correct Needle Size
To avoid damaging the silicone seal or causing blowback, always use a filling tip with a 2.9mm diameter or smaller.
A smaller fill needle:
- Fits perfectly into the CBS center-fill opening
- Prevents overflow
-
Protects the airflow structure inside the device
*Step 3: Only Fill Through the Center
This is the most important part of the process.
CBS Pens have airflow channels on the sides — these are NOT fill holes.
Filling oil into the side holes will cause:
- Clogging
- Gurgling
- Oil in the mouthpiece
-
Failed hardware
Always fill straight down the center of the silicone gasket, where the fill port is located.
Think of the CBS system like a bucket — you’re filling the bucket through the center, not the sides.
Best Practices for Filling CBS Pens
To maximize performance and reduce failures, follow these pro tips:
- Fill slowly to avoid back pressure
- Keep the pen upright during and after filling
- Allow the oil to settle before capping
- Use a handheld press, an arbor press or even press with your hand to close the cap evenly
-
Let the hardware sit upright after capping so the ceramic can saturate (especially with thicker oils)
