CO2 Shifter Bottle Position Clarification
Shifter CO2 bottle has been mounted horizontal for years.....but I have read many times that the bottle must be mounted vertical........is this something that has been "lucked up" on and needs to be corrected ??? Any help on this monumental inquiry ???

Re: CO2 Shifter Bottle Position Clarification
I went through the General section of the '20 book and found no restrictions as to orientation. General 9 8 says CO2 and other listed inert gasses only and no hose clamps. Sounds like one of those local tech things. You know "I don't like that. Fix it"

Re: CO2 Shifter Bottle Position Clarification
This probably needs the question clarified.....not the safety issue but the operational issue.......the bottle is to be mounted vertical only to work properly not horizontal, is that correct ???

Re: CO2 Shifter Bottle Position Clarification
A CO2 bottle contains a gas. Will work properly mounted in any position.

Re: CO2 Shifter Bottle Position Clarification
Just spoke to my Welding supply Depo and they say that there is liquid and gas in a CO2 bottle, so the valve must be the highest point when mounting the bottle.

Re: CO2 Shifter Bottle Position Clarification
It is correct that the common small aluminum bottles we use in racing do contain approximately 10 oz of liquid co2 when properly charged. So, in theory, an upright position is the correct orientation. However, I also see them mounted horizontally without problems.

Re: CO2 Shifter Bottle Position Clarification
Bottle is not a dip tube type so orientation doesn’t matter

Re: CO2 Shifter Bottle Position Clarification
All cylinder should be stored in their upright position to ensure it is used appropriately. For example, if a CO2 cylinder is laid down it could dispel liquid CO2 in a non liquid CO2 application, which could cause severe problems. Please refer to the article linked for Cylinder Safety.

Re: CO2 Shifter Bottle Position Clarification
Orientation does matter.
When a CO2 bottle is filled is mostly full in a liquid state and boils off to a gas as it is used. If you carry a bigger bottle to fill your small bottles used on the race car the bottle needs a dip tube to the bottom or turn the larger bottle upside down to get the liquid out into the smaller bottle in its regular upright position. We use CO2 in the place of air in a bottle so we do not need to fill nearly as often. I carry a 30lb bottle to fill out of if needed. I fill my 2.5lb bottle once a year and unless I have a leak it last all year long. Shifter and throttle stop both use out of the bottle. With a air filled bottle it would not last a full race of 6 to 8 rounds. With a horizontal mounted CO2 bottle you could get liquid into the regulator and could cause issues. I have seen people mount them in a horizontal position however, in most cases they are tipped up a little and the valve faces the front of the car and the regulator connection facing up.
