Overview

The YHXMARSCAN CO2 adapter provides a practical conversion from CGA320 to TR21-4, enabling compatible connections for soda machine refills. Designed for straightforward setup, it helps you create a reliable link between components while avoiding common fit issues. Note that this adapter is not suitable for CO2 tanks that use a W21.8-14 joint.

Why this adapter matters

  • Compatibility: CGA320 to TR21-4 configuration supports typical soda machine refill systems.
  • Secure connection: Designed for a tight, leak-minimized seal when properly connected to the cylinder.
  • Durable build: Constructed with materials chosen for long service life and dependable performance.

What’s included

  • 1 CO2 adapter
  • 8 O rings for enhanced sealing and reliability

Installation and use

  • Easy to install with empty CO2 cylinders; follow the visuals to align correctly.
  • Good air tightness helps reduce gas leakage during connection to the cylinder.
  • O rings are sized for a snug fit and may require firm seating to create a reliable seal.

Notes and support

RPV pin is not included. If your donor tank has a residual pressure valve, a suitable pin may be required. We provide around-the-clock support for questions or assistance. If refilling is difficult while the tank is upright, try inverting the tank, as some units lack a dip tube.
