    Yes, that's what I'm thinking... They will be for submersible Aquarium heating elements. I have two that the glass tubes were broken and most would just toss them but if the internal parts are fine, they are still in working order. So why waste them if I can find the Tube for them. They are like $35+ each new.

    Now that I know what they are for, I will try to use my Macgyver power and think of some alternate solution with something that's readily available...no promises though.

    I find Fisher, Carolina, etc. scientific suppliers a good source of info. They have 1 800 numbers and can supply most size or refer you to a source. However buying just a couple might not save anything. Not sure exactly what you need but tubes used for specific gravity, temperature, etc. might work.

    Ha haa. Sounds good Mac! Normally I'm pretty good at hunting this kind of stuff down and is why I ended up here... It was kind of like a "Help me Obi wan, you're my only hope" type of situation. Thanks Fossil. I'll try them as well.

    It's for a replacement glass tube on an aquarium heating element.

    Sorry...I couldn't come up with any alternative.
