Silicon carbide balls pass heat into the air faster than any other material available for the Tempest cap. The set holds around 50 pieces at 3 mm.

That conductivity means heat moves through the ball bed with maximum intensity, giving the most intense extraction character of any ball material in the range. Cap fill weight is 2.2 g, lighter than the standard zirconia, and in daily use silicon carbide balls perform close to ruby balls, with a slightly different flavour signature.

The material is hard and stays stable through repeated heating. A retaining screen in good condition keeps the ball fill securely in place.

Intended for use with: Tempest 2.
