    Can I just fill it in?

    I have a job I have to do tomorrow. A wires insulation got rubbed away and the bare wire hit the suction line causing a pin hole. Normally I like to cut it out and put in a coupling. But this is in a tight spot on a bit of a curve. It looks like it would be pretty easy to just braze over the pin hole. Its even slightly recessed due to the shorting of the wire. It looks like I could build up the solder real nice. What do you think?

    I've done that before, its pretty easy especially with a small pin hole. Get the surface clean, heat the area, and fill it in with some silfos 15.

    Yep fill it in.... I've filled 3/8" holes before in condenser coils before you'll be fine.

    Glad to see that this is an acceptable method. Just did the exact same thing to a pin hole in a liquid line 2 weeks ago. Makes me feel better about it lol

    Yes, you could cross the Grand Canyon with 15% silfos

    true statement, im embarrassed to admit to what i have filled in with 15%. i have had 90 degree joints blow apart, never seen one fail at the braze joint. i did this exact repair in about 2 hours on friday. braze it then i like to build up a good puddle and when available i like to do a solid ring of solider around the pipe, then its holding onto it self not the copper.

    Wouldn't say its acceptable. But if someone says they have never done it, they are lieing to you.

    I don't see why filling a pin hole with silfos isn't acceptable. I have come across many Carrier splits they strapped compressor leads directly to suction line right at the bend and the vibration caused a short and blew a hole. Every one of them I fixed this way with no adverse effects. I did a better job than the factory because I put a piece of pipe insulation between so it wouldn't do it again.

    You would have to be terrible at brazing to cause a restriction filling a pin hole
