We just sent you an entire new valve stem to include the hookups for it. The DHL tracking number is DHL Tracking # 58-6360-2290. Please be advised that this type of valve is very sensitive to pressure and strength. When using the knob to open and close the bottle flow, you should never have to force it to stop the gas or allow more gas to go into the chamber. The valve can be damaged easily if you do that. When you receive the part if you need help putting it on please let me know. I did replace this valve on a machine a month ago so I am familiar with how to do it.
Thanks,
