Aquascaping Essentials CO₂ Sodastream Adapter – Side-Entry

• NZ Sodastream Compatibility: Converts standard NZ Sodastream (Blue) cylinders to the W21.8 / DIN 477 regulator thread.
• Saves Space: Unique 90-degree side-entry repositions the cylinder horizontally—critical for cabinet setups and nano tanks.
• Solves Clearance Issues: Eliminates vertical space problems and prevents interference with bubble counters.
• Built-in Flow Control: Features a knurled control knob for manual CO₂ regulation.
• Premium Build: Lightweight, durable construction from anodized aluminium alloy.
• Easy & Safe Install: Tool-free installation with a crucial safety feature (closed knob before connection).

The Aquascaping Essentials Aluminium Sodastream CO₂ Adapter is the ideal solution for New Zealand aquascapers who want to use standard Sodastream cylinders with their existing aquarium CO₂ regulators.

This clever adapter serves two main functions:

1. It converts the NZ Sodastream cylinder thread to the industry-standard W21.8 (DIN 477) regulator inlet.
2. Its unique 90-degree side-entry design addresses critical space limitations by allowing the cylinder to be repositioned horizontally.

This horizontal setup solves two common setup problems:

• Vertical Clearance Issues: No more struggles fitting the cylinder and regulator inside aquarium cabinets or beneath low shelving.
• Bubble Counter Interference: The horizontal position ensures the cylinder doesn’t obstruct large, regulator-mounted bubble counters.

Key Features

• Thread Conversion: Connects NZ Sodastream (Blue) cylinders to all W21.8 / DIN 477 CO₂ regulators.
• Space-Saving Design: The 90-degree side-entry repositions the cylinder horizontally, perfect for cabinet setups and tanks with restricted vertical space.
• Flow Control: Features a knurled control knob for manual CO₂ flow regulation.
• Durable Build: Machined from lightweight, yet robust, anodized aluminium alloy.
• Ready-to-Use: No tools required for installation and includes a spare sealing washer.

Important Safety and Installation

Safety Note: Before attaching the adapter to your Sodastream cylinder, you must ensure the control knob is fully turned counter-clockwise (closed). This prevents the internal pin from opening the cylinder valve prematurely.

Installation Instructions:

1. Confirm the adapter’s control knob is fully closed (turned counter-clockwise).
2. Screw the adapter onto your NZ Sodastream cylinder until it is hand-tight.
3. Attach your existing aquarium CO₂ regulator to the W21.8 outlet.
4. Once all connections are secure, slowly open the control knob to release the CO₂.
5. Use soapy water or leak detection spray to check all fittings for leaks before leaving the system pressurized.

The adapter comes pre-fitted with working seals and is ready for immediate use.
