These CO2 regulators are very high-priced compared to a regular $15 gas regulator. I only need CO2 for a 100 PSI and under. Can I get away with something 15 to 20 bucks at my local hardware store?

CO2 regulators are built to handle extreme cold and condensation, the cheap air regulators at ACE are not.
This should've been asked in the stupid questions thread.

Well it is made with the same materials so I don't see what the real difference is why cold or condensation would be a variable

CO2 is stored at pressures easily exceeding 800PSI. This alone is far above what a normal compressed air regulator is rated for. Did you not even look at how high that inlet pressure gauge goes?

But they are both gasses? What difference would it make?

It’ll freeze and burst open. If you’re lucky you won’t get hit by shrapnel.

>pressure ratings

If you find a fart pressure gauge in the 800-1k psi range, go for it turbo. Since specifics don't matter.
Buy the wrong part, if you survive let us know the cost of the medical bills so we can giggle.

Chemical compatibility ya dingus.

You can run diesel in gas engines you just have to replace the spark plugs with glow plugs vic-a-vers-a

It will work just fine. Here are some regulator facts.

NEVER run oxygen or oxygen enriched air or other mixture through a titanium regulator it WILL cause a fire.

Chemical compatibility is only a concern with reactive gasses (carbon dioxide is inert no issuess)

The lighter the gas the easier it leaks because its molecules are smaller. Opposite for heavy gasses. This means helium could leak through something that is air tight.

Always back the regulator of and bleed to atmosphere after use. If it's for a keg and you don't want to that's ok, but it will wear out faster.

Co2 regulators for kegs are lubricated with food grade lubes. You can oxygen clean a cheap regulator by pulling it apart and scrubbing with hot water a dawn or joy dish soap. Replace lube with food grade.

>> No.1616380

>>1616377
Let me rephrase that last one. Pulling it apart and scrubbing will make it oxygen clean. Lubricating with an oxygen safe lubricant will make it safe for oxygen use. Using food grade lube will make it food safe for food contact. Nothing makes titanium oxygen safe.

Don't go blowing yourselves up now.

As someone who handles a lot of gasses at work and home (nitrogen, argon, hydrogen, CO2) don't fuck around with high pressure and get something decent
