Perlage regulators ship with stems designed to fit CO2 cylinders in North America, or more specifically, the CGA-320 standard. However, because no uniform standard exists worldwide, our regulator will likely not be compatible with your CO2 cylinder.

 

For this reason, we remove the stems on our regulators before shipping internationally, and you must source and install a stem and nut that matches your local CO2 cylinder before attempting to use the system.

 

On Perlage regulators, the stem attaches to the regulator body with 1/4" NPT right-hand threads. As long as your local stem has 1/4" NPT right hand male threads, it can be safely screwed into our regulator. IF NOT, PLEASE CONTACT US.

 

CAUTION:
The regulator stem shipped with your system has been removed (but included). Do not attempt to attach to a CO₂ source until the proper stem has been installed and tightened.

 

NOTE: There are two variants of the Perlage Commercial Pressurizer, the Pro model and the Basic model. The only difference between the two is the regulator: The Pro model has a chrome regulator with a gauge; the Basic model has a brass regulator with no gauge. The instructions differ slightly depending on which model you have.

Procedure for Pro Model Stem Swap

1. Identify the threads used on your CO2 tank to determine the required stem. This information can often be found just under the main valve at the top of the cylinder (Figure 1). Now procure a new or used CO2 regulator (or nut and stem) in your location that matches this standard. 

Note: it is very unlikely that you will be able to find any CO2 regulator that is NOT the appropriate standard for your country, so this should not be a difficult task.

2.  We have included a fixture to help you hold the regulator securely for the procedure of installing a stem that’s required for your CO2 cylinder. Insert the round body of the regulator into the narrow end of the stem removal tool until flush (Figure 2).

Note: We recommend a vise for the following steps, but if one is unavailable the procedures can be accomplished with an extra set of strong hands.

 

3.  With the gauge facing you and the regulator stem pointing to the right, place the assembly in a vise and tighten until secure (Figure 3). AVOID PUTTING PRESSURE ON THE GAUGE when removing/installing regulator stems if you go this route—the gauge is delicate and easily bent. DO NOT OVERTIGHTEN—the vise is merely meant to hold the regulator in place while installing the stem.

 

4.  With the regulator still in the vise, wrap the threads of a regulator stem compatible with your CO2 cylinder with the supplied pipe tape (Figure 4). Wrap the tape around the threads counterclockwise (i.e., opposite the direction that you tighten the stem) for three or four turns.

 

5.  Screw the stem into the regulator by hand until tight. If your stem threads in smoothly by hand and tightens securely, you are doing it correctly.
If it does not thread smoothly, stop and contact us.

 

6.  Using a wrench, tighten (approximately) another one and a half to two revolutions, or until firmly secure. You can use a 11/16" socket or box wrench on the end of the stem to tighten it, or use a 7/16" wrench flat on the stem to tighten (Figure 3).

 

 

 

Procedure for Basic Model Stem Swap

1. Identify the threads used on your CO2 tank to determine the required stem. This information can often be found just under the main valve at the top of the cylinder (Figure 1). Now procure a new or used CO2 regulator (or nut and stem) in your location that matches this standard. 

Note: it is very unlikely that you will be able to find any CO2 regulator that is NOT the appropriate standard for your country, so this should not be a difficult task.

Note: We recommend a vise for the following steps, but if one is unavailable the procedures can be accomplished with an extra set of strong hands.

 

2.  Basic Model: With the hose coming out the top of the regulator body and the regulator stem pointing to the right, place the assembly in a vise and tighten until secure. DO NOT OVERTIGHTEN—the vise is merely meant to hold the regulator in place while installing the stem. A vice is not required for this step. You should be able to develop enough torque by holding the regulator body firmly in one hand and tightening with the other.

 

3.  With the regulator still in the vise, wrap the threads of a regulator stem compatible with your CO2 cylinder with the supplied pipe tape (Figure 4). Wrap the tape around the threads counterclockwise (i.e., opposite the direction that you tighten the stem) for three or four turns.

 

4.  Screw the stem into the regulator by hand until tight (Figure 5). If your stem threads in smoothly by hand and tightens securely, you are doing it correctly.
If it does not thread smoothly, stop and contact us.

 

5.  Using a wrench, tighten (approximately) another one and a half to two revolutions, or until firmly secure. Use a 11/16" socket or box wrench on the end of the stem to tighten it (Figure 6).
