Mad Heaters Thermal Extractor Balls
Highlights
- Custom performance: Swap ball materials to fine-tune heat transfer, session length, and extraction style.
- Dial-in airflow feel: Choose 2.5mm for a slightly tighter draw or 3mm for a more open inhale, depending on your setup.
- More consistent heating: Ball media helps spread heat evenly through the thermal matrix for repeatable results.
- Faster or slower response: High-conductivity options (like SiC) ramp heat quickly, while others lean toward steadier heat retention.
- Flavor tuning: Different materials can shift the flavor profile and perceived smoothness.
- Easy to refresh: Great as a replacement set when your existing media gets worn, lost, or you want a backup.
- Made for thermal matrices: Designed for caps/heads that use ball media to store heat and drive convection through the bowl.
- One product, multiple variants: Pick your preferred material and size from the same product page.
In the Box
- Thermal Extractor Balls (selected variant): One bag of ball media in your chosen material and size for use in compatible thermal-matrix caps/heads.
Overview
Thermal Extractor Balls are precision ball-media inserts used inside compatible thermal-matrix caps/heads (such as Tempest-style caps). They store heat and help deliver hot, convection-driven airflow through your bowl, letting you fine-tune how your setup hits.
Choose your preferred material (Zirconia, Stainless Steel, SiC Silicon Carbide, Quartz, or Ruby) and size (2.5mm or 3mm where available). Smaller balls generally increase surface contact and can feel a bit more restrictive, while larger balls tend to open airflow and change heat behavior.

FAQs
- What are thermal extractor balls used for? They’re used as “thermal media” inside certain vaporizer caps/heads to store heat and push hot air through your material for convection extraction.
- Are these for dry herb or concentrates? These are typically used in dry herb convection systems that use ball media inside the heater/cap (not in concentrate atomizers).
- Which size should I choose: 2.5mm or 3mm? 2.5mm often feels a bit tighter and can increase heat contact; 3mm is commonly a bit more open and can shift how the heater responds. Your preference and device design matter most.
- Do different materials really change performance? Yes. Materials differ in how quickly they move heat (thermal conductivity) and how they feel during a session, which can affect warmth, density, and flavor character.
- How many balls come in a bag? It varies by size, but a bag is typically enough to fill one compatible cap/thermal matrix with some extra.
- Do I need anything else to use these? Your device must be designed to hold ball media securely (usually with a retaining screen or internal chamber made for balls).

- What this product is: Small, heat-resistant balls that live inside certain vaporizer heater caps/heads to help store and distribute heat.
- Why people use them: They let you “tune” how your device behaves—airflow feel, how quickly it heats up, and how long it stays hot.
- What it’s compatible with: Only caps/heads designed for ball media (thermal-matrix designs). If your device doesn’t have a place to retain balls safely, these won’t fit.
- How to pick a variant: Start with the size your device shipped with. Then experiment: 2.5mm for a slightly tighter draw, 3mm for a more open feel; try different materials to chase your preferred balance of flavor and intensity.
- Safety note: Use only in devices intended for ball media, and keep small parts away from children and pets.
