Description
xUpgrade your CO2 refilling workflow with the MONKEMON CGA320 CO2 Refill Adapter Hose. This 36-inch braided stainless-steel hose blends rugged durability with precise control, thanks to a built-in pressure gauge and two on-off valves for filling and venting. The long reach helps you maneuver around tanks and dispensers, reducing strain and clutter in busy setups. Note that the 36-inch hose is not compatible with pink quick-connect systems, so please check your equipment before purchasing.
What this kit helps you do
Designed for hobbyists and small setups, this adapter enables transferring gas from larger CO2 tanks to smaller cylinders with greater convenience. The dual valves let you fill and vent as needed, while the gauge offers a real-time readout of pressure so you can gauge when to stop. The stainless steel braid adds a tactile sense of resilience, and the 36-inch length minimizes repositioning of your equipment.
- Precise control: gauge-based monitoring supports careful refills
- Safe operation: separate filling and venting valves reduce risk
- Durable construction: stainless steel braided hose resists wear and heat
- Extended reach: 36-inch length helps you work from a comfortable distance
Key compatibility and setup tips
The inlet thread is CGA-320 (G1/2), intended for US and Canada, not for UK or continental Europe. The outlet thread is TR21-4, fitting many soda CO2 bottles (FIZZI, ONE TOUCH, JET blue cylinders). It is not universal; please verify thread types before purchase.
- Inlet: CGA-320 (G1/2) for US/Canada
- Outlet: TR21-4 compatible with common soda cylinders
- Not compatible with paintball tanks or some water dispenser models
Usage notes and support
To maximize filling efficiency, you may pre-chill small cylinders for a few hours. Ensure the large cylinder has sufficient pressure and, if needed, position it upside-down or on its side. If the thimble is too thick, replace it. We stand behind this product with a full year of support and guidance.
- Pre-freeze small cylinders for easier fills
- Ensure ample pressure in the large cylinder
- Follow the included instructions for safe operation
