Plastic bottle explodes filling with co2 tank

[onderdoor]

Hi guys, I tried to make carbonated water with co2 tank when filling the bottle with co2 the pastic bottle exploded. What did I do wrong?
I'm glad I didn't try with glass bottle.

What pressure were you carbing at? I've never gone over 25 using plastic. To that point, I would never put pressurized gas straight into glass.

I wasnt looking at the pressure it was like in 5 sec maybe less. I was looking at the bottle and exploded realy fast. I don't see anywhere how I can regulate the pressure. I think. I have never done it before. its my first time trying a co2 tank

so I miss a device to regulate the pressure

That's a welding regulator calibrated to flow in litres/second... not meant to maintain pressure.
I'm actually surprised the tied-down-with-string instead of a hose-clamp didn't pop off the regulator barb first.
Are you using a carb-cap on the bottle and ball-lock disconnect? I also notice there is no shut off valve on the output.

I think you mean this? carb cap

take the pressure off I use the blue cirkel

can you tell me which one i need to regulate the pressure

Honestly you need a different regulator. The ones used for beverages have an output gauge that measures pressure in bar or psi (or both). Here's an example:

The part you circled in blue is the PRV (pressure release valve) and is there to protect the regulator itself from over-pressure.
The pressure itself is adjusted by turning the big knob.

thank you

You're actually lucky you didn't make the grey disconnect explode. Those are only rated at about 60psi. PET soda bottles will burst at about 100psi.

PET soda bottles will burst at about 100psi.

Is this one of those "(don't) ask me how I know" things?

I finally get the right regulator.
I think I filled it up, but it tasted wierd and no bubbles. It was just still water.

I filled the 1,5liter bottle with water like 90-95% full.

First I opened the tank without the bottle so I can adjust psi to 25.

After that I released the air out and connected to the bottle and opened the tank again. While I was shaking the psi went to 20. I opened the regulator more it went to 25. I closed the tank and shaked more, seeing the psi went to 30. I realised the air out and tasted the water. There where no bubbles and water tasted wierd.

Totally shaked was 20 sec. What did I wrong?

do need to take the air out of the bottle so it can fill more co2 in? (Squeeze the bottle)

While I was shaking the psi went to 20

While you were shaking, you dramatically increased the available surface-area of the water resulting in significant absorbtion of CO2..this is why the pressure appeared to drop....CO2 was still flowing, just faster causing the gauge to drop. Carbonation is all about temperature/surface area/time. Leave the regulator at 25 psi...it's only absorbing some of the CO2 but it takes time to achieve equillibrium. Are you keeping it in a fridge? ...it will take at least a little while.
