Regulate your airflow.

When CO2 cartridges were first developed in the early 1980s, inflating your tires accurately was a bit troublesome. With Silca's invention of the EOLO, the user finally had the ability to control the flow of air, making cartridge use much more mainstream. The EOLO III is the latest version of Silca's simple CO2 inflator.

The EOLO III was constructed using an ultra-precise spool valve design with light action spring. This ensures control of airflow into the tire. The EOLO III contains no plastic parts. It is made in the USA from Alcoa aluminum and stainless steel. Three rings on the body improve your grip and shield your hand from the cold flow of the CO2.

Silca's EOLO III comes with two 16-gram cartridges. Silca considers its CO2 cartridges the best in the industry, as they guarantee that they hold 15.5-16 grams, while a 16-gram cartridge is only required to hold 14 grams. They are produced in Austria by the same manufacturer who produces most of the cartridges for airbags and life vests.

The Silca EOLO III - CO2 Regulator with 16gr Cartridges is available in the color Red.

  • Gives you control over airflow
  • Rings for grip and comfort
  • 2 16-gram cartridges included

  • Familiarity: I've used it several times

Silca does not make cheap stuff. They don’t source cheap material, and they definitely go all out on design. This may look like the average CO2 inflator, but it’s hardly that. Made from 6063 series aluminum and stainless steel, this piece allows the ability to regulate the flow of air with design, precision, and function at the forefront. When I purchased this I realized I already had 3 other inflators, but now I can say I truly have ONE.

Most of the top pros in endurance MTB racing are using this valve. It's very well made and worth the cost.
