## Description

desertcart.com: CESARIAS M181.5 Thread Replacement Valve CO2 Tank Brass Pin Valve for Soda Stream : Industrial & Scientific

Review: It works - It does work to convert a regular, soda stream cartridge that is design to prevent consumer refilling to one that ca consider can refill with the correct adaptorsa and a source of CO2.
Review: Good replacement for refilling CO² at home - These replacement valves allow easier refilling of SodaStream and similar brand CO² tanks. The hardest part may simply be getting the original valve off the tank if you didn't have a bench vise with soft jaws or a friend with really strong grip. I put a very small amount of food safe lubricant on the O-ring when I replaced the valve which made seating it well a bit easier. This will easily pay for itself after a number of refills off a bulk tank at home vs exchanging tanks in-store.

### ⭐⭐⭐⭐⭐ Works great
*by M***G on December 4, 2019*

I replaced the valve in a sodastream Co2 bottle with this one and was able to fill my sodastream to near capacity from a CO2 tank that I purchased from a local welding shop.(A separate adapter is required to mate the CO2 tank to the sodastream bottle). When finished filling, the sodastream weighed 1020 gm., not far off of its maximum fill weight of 1070 gm. In order to achieve this fill weight I placed the sodastream canister in the freezer for awhile ( a couple of hours) and then filled it from a C02 tank that I inverted. I'm not sure how long it's necessary to cool the canister to maximize filling ( actually forgot that it was in the freezer), but just out of curiosity I initially filled it without putting it in the freezer. After filling it weighed 810 gm. So cooling the sodastream bottle produced very good results. I will be buying another one of these. It took awhile to receive it from overseas, but it was worth the wait. It feels good to jury rig the setup so that I don't have to pay for expensive refills. Take that Sodastream!
