Product Information

Open the valve on the CO2 cylinder to inject gas into the cylinder. You will hear gas flowing into the cylinder. The refilling adapter also has a dump / purge valve to safely release the residual gas within the adapter once refilling is completed. Instructions

Three scale pressure gauges acc. to ISO 5171 with high contrast pointer for better gas pressure clarity These can be obtained from most supermarkets and adapters can be bought so they will fit regulators for standard cylinders. These include various sizes (1kg, 2kg, 5kg etc) and are available from places like BOC, Energas, Pub gas suppliers, Hydroponics shops etc. A bottle will typically last for 3-4months when used at a rate of 1 bubble/second for 8 hours per day, which makes it ideal for aquariums up to 200 litres.

UK Bayonet (W21.8) to ACME Filling Point Adapter

I'd a couple of small cylinders that I wanted to use as "receivers", or reservoirs of CO2 when the cylinder is shut off (I wont try and explain why I'm doing that here) so these repurposed cylinders and connectors will only see about 60PSI. The pin inside the adapter will depress the valve on the SodaStream cylinder to open the flow of gas. There are quite a few Different types of cylinder available for us to use in our aquariums and people are often confused as to which type of cylinder and what connections it may use. The high pressure corrugated hose consists from two ends (DN6). The inlet is equipped with pre-assembled cylinder valve adaptor according to national standard, outlet connection for DN6 has W21,8 for air gases and CO 2, W21,8LH for flammable gases. Corrugated hose is covered by stainless steel braid and safety line. The set is pressure leak tested. APPLICATION Holding the SodaStream cylinder firmly with one hand, tighten the adapter/regulator to the cylinder using a wrench or spanner.

The Refilling Adapter is designed to allow refilling of DIN 477 / W21.8 / BS 341 No. 8 CO2 cylinders, or you can add an adapter for refilling of SodaStream or Paintball / CGA 320 cylinders. The refilling adapter also includes a pressure gauge to ensure the pressure of the donor cylinder will not exceed the pressure specification of the recipient cylinder. The CO2 Refilling Adapter is used to safely refill cylinders from larger donor cylinders. It is designed to connect to either a CGA 320 or DIN 477 / W21.8 / BS 341 No. 8 donor cylinder, and then connect either directly or via a high pressure hose to the recipient cylinder. Stainless steel corrugated hoses with the pre-assembled cylinder valve adaptor. Working pressure up to 300 bar. Robust design according to ISO 10380. The male/output thread on the adapter is made to DIN477 / JIS m22-14 / W21.8-14 / .860"x1/14 (covers UK, Europe and Asia) specifications, which will fit industry standard regulators.SodaStream cylinders provide a cheap and convenient way of obtaining your CO2 source. However, the design of the cylinder valve's thread does not conform to any industry standard thread gauges and therefore cannot be used directly with a regulator. Our SodaStream adapter enables you to use a SodaStream cylinder just as you would a 'normal' CO2 cylinder. You can obtain the cylinders from high-street shops, making it ideal for use in aquariums, homebrewing and other hobbies. High quality, durable construction. These have special threads only produced by sodastream these are all the same connection except if you get the cylinders from New Zealand or Austrailia which are different from the rest of the world .
