The 3 Insulating rings on the EOLO body improve grip and insulate from cold during inflation. The EOLO III builds on the SILCA tradition by using an ultra-precise spool valve design with light action spring to give you perfect control of the flow into the tire. The full metal construction contains no plastic parts and is manufactured entirely from 6063 series aluminum and stainless steel. The 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.
