The Silca Eolo IV CO₂ Inflator (Black/Red) is a compact, precision-built CO₂ inflator head designed for fast, reliable roadside tire inflation. Building on SILCA’s legacy as the inventor of the regulated CO₂ inflator, the Eolo IV lets riders control the flow of gas into a tire with an easy-to-use, knurled control knob, helping reduce wasted CO₂ and allowing more accurate inflation.
Constructed from all-metal materials (6063 aluminum and stainless steel) with no plastic parts, this lightweight inflator head is engineered for durability and long service life. The hardened tool steel puncture pin ensures smooth cartridge piercing even after repeated use, and spring-regulated airflow gives consistent performance.
The head is compatible with threaded CO₂ cartridges (sold separately) and works with both Presta and Schrader valves, making it versatile enough for road, gravel, and mountain bikes. Its low-profile design fits easily in a jersey pocket, saddle bag, or pack so you can carry it on every ride.
