Cylinder Valve Disabling Tool

GD-Tool-Kit-Group.jpg GD-Tool-Attached.jpg  

Model RTCGA600: For use with 17L & 34L steel cylinders.
Model RTCGAC10: For use with 34L, 58L & 74L aluminum cylinders and 103L steel cylinders.

These tools are designed to render the DOT 39 cylinders listed above incapable of being refilled by removing the valve stem. Federal law prohibits the refilling of these cylinders subject to 5-years in prison and a $500,000 fine. Empty cylinders that have had the valve stem removed may be returned as non-hazardous material (prepaid freight) to Gas Dynamics for recycling or you may recycle them locally.

Directions for use:

1. Use caution when working with compressed gas cylinders. If you are unfamiliar with their use, contact someone who is knowledgeable.

2. Determine the cylinder/valve type to select the proper valve stem disabling tool.

3. Wear safety glasses and proceed slowly.

4. Cylinders must be empty before proceeding. Install the appropriate regulator on the cylinder. Open the regulator in a well-ventilated area until all pressure in the cylinder has been exhausted. Do not rely on the regulator pressure gauge to measure for zero pressure. Failure to relieve the cylinder of all pressure before using the valve stem removal tool will most likely result in serious injury or death. A demand flow regulator can not be used to relieve cylinder pressure.

5. Prepare the tool for use by ensuring that the center punch is fully retracted into the body of the tool before proceeding. The center punch is retracted by turning the body of the tool counter-clockwise until it stops.

6. Hold cylinder with valve pointed away from your face.

7. Install the tool on the cylinder as you would a regulator. Do not use wrenches or pliers to attach the tool to the cylinder. Use only hand pressure. Do not use the tool if it fails to engage properly with the cylinder threads, otherwise injury may occur.

8. After the tool is connected to the cylinder, turn the handle clockwise until you have reached the end of its travel. You will feel increasing resistance as the punch pushes out the valve stem into the cylinder. Some venting of residual pressure may occur during this process. If this does happen, pause to allow the gas pressure to dissipate. The valve stem disabling tool is designed with gas relief ports to facilitate safe venting in the event the cylinder contains residual gas.

9. Retract and remove the tool by reversing the procedure in step 8. After retraction, there will be a visible hole in the cylinder valve previously occupied by the valve stem. The valve stem should be inside the cylinder and will rattle when the cylinder is shaken (not stirred).
