Delivery time: 3-5 days
The Cardihaler Converter W21.8-14 connects the Cardihaler regulator (TR21x4) to larger CO₂ cylinders with a W21.8-14 valve (21.8 mm diameter, 14 threads per inch), the standard in Europe and most of the rest of the world. The same thread has local names, including DIN 477 No. 6 (Germany), BS 341 Part 1 No. 8 (UK) and NF type C (France). It enables a secure and airtight connection with approved Cardihaler components. Cylinders compatible with SodaStream screw-in connect to the regulator directly and do not need a converter. Included with Cardihaler orders to the EU, Australia and New Zealand. Sold separately for all other orders. Intended as a replacement or additional component for Cardihaler users.

CO2 Academy
Carbon dioxide (CO₂) is a key regulator of human physiology, influencing respiration, oxygen delivery, circulation, blood pH, and nervous system function. This resource presents a curated selection of peer reviewed research on how CO₂ levels shaped by breathing patterns or therapeutic applications affect physiological regulation, without making health or treatment claims.
