    gluing copper pipe fittings
    comic sans ms5 Hi I'm very new to forums so I don't know if I'm even in the right place so please forgive my mistakes hopefully I'll learn how to do this without losing my sanity or driving anyone crazy. So here is my question I need to know if it is possible to glue copper pipe I don't like playing with fire and there will not be any water used in them or electricity running through either and can they be painted with spray paint? Yes that was two questions and yes my math is that bad. Please any help Thanks in advance jo

    Don't try it. Maybe you've been tempted by the variety of adhesives that bond metals, but don't try it on a copper supply line.

    You can, though, get an adapter to go from copper to cpvc - so you can glue the rest of it.

    One option would be a fitting like this

    To go from the copper to cpvc - and glue it all from there.

    I suggest, though, going one step better to avoid having a compression fitting on your line: Have someone solder a male or female adapter on for you so you can screw cpvc into it and go from there... a fitting like one of these:

    It'll be downhill from there!

    Is this more mechanical than fluids? About 10 years ago in an effort to get away from lead based solder for drinking water, there were epoxies sold for this. Haven't seen any lately. May be an idea that didn't work. Depending what you are doing, I don't see a problem with an epoxy. It still means cleaning the joints good. It may not have the mechanical strength or heat resistance of solder, but depending what you are doing, it may be OK.

    And yes, paint it. A paint meant for metal might stick better and chip less, but ordinary latex will work.

    I apologize. I missed that small word "not" in the original post - as far as water going through them...

    Sometimes my fingers go faster than my eyes and brain :o

    Yes, If nothing is going through them under pressure, then any adhesive that is designed for metals - and specifically copper - will do you just fine.

    Ricks answer was exactly what I would have recommended, (especially the PVC male adapter) and Labman elaborated on it. Let me throw my 2 cents in. Yes there is a "cold solder " for copper on the market. It's called "Just For Copper" and to check it out click on, In the future may I suggest that if you have a plumbing question that you post them on the plumbing page. Good luck, Tom
