    Hi All,

    How easy/difficult is it to replace the solenoid on a CO2 regulator?

    I have attached a pic of the setup I currently have.
    Are there any special precautions I should follow?
    Does anyone know of any howto's, etc. that would help?

    TIA

    On the kit you have, it's fairly easy. I'm on my phone right now, but there's a thread where I guided Trev Pleco through it. Try and search for it.

    To reconnect the solenoid to the regulator, should I use some PTFE tape to seal the threads?
    And then I can check for leaks with some soapy water?

    Have you determined whether it still clicks on\off?

    You can have a read through the link below and see vid too.

    If there's a washer\seal\o-ring , it may not be necessary. If however they used thread-locker then generally yes.

    When I plug it in to power, it does click.
    I cant recall if I hear it make any sound when it is unplugged (switched off).....

    If it clicks as soon as you plug it in my logic depict that it was closed and opened up when you plugged it in.Could your problem perhaps be els where?

    I have a solenoid that clicks when plugged in and out, but stays open. It's a SAGA, go figure.

    The reason I generally ask this question is just to determine that the fault is not electrical. We already know that it is not, so next step in debugging is to determine whether it opens and\or closes fully. We now know it opens but doesn't close properly, which may suggest a mechanical fault at seal or armature tube possibly.

    Maybe dirt even a small dust particle in the wrong place can wreak havoc on sensitive equipment.
