Silca EOLO III CO2 Regulator ONLY

In 1982 SILCA developed the first regulated CO2 inflator. As Claudio himself explained, "Before EOLO, you had to turn the cartridge and pray!" Giving the user the ability to regulate the flow of gas into the tire was the key to the widespread adoption of compressed gas for roadside use. EOLO III builds on the SILCA tradition by using an ultra-precise spool valve design with a light-action spring to give the user perfect control of the flow into the tire. The full metal construction of the EOLO III contains no plastic parts and is manufactured entirely from 6063 series aluminum and stainless steel. Hardened tool steel puncture pin is more than 2X the hardness of traditional puncture pins to ensure smooth operation in all conditions over many years.

- 6063 series aluminum body with Red-White-Green Insulators
- Lightest spring action of any spring-valve regulator
- Hardened tool steel puncture pin
- 'Camera-lens' style valve head allows for easy installation even in disc wheels
