  • Using wire brush after swaging/before brazing


    Does anyone clean the inside of their swaged ends with a wire brush before brazing? Sanding and deburring the male end of pipe are industry standards but it doesn’t seem like there are wire brushes on the market sized for hvac line sets, which makes me think no one really does this step. I’ve only seen it done one time on a brazing tutorial video by Lucas Milhaupt.







  • The copper should be shiny clean on the inside, “never” exposed to ambient air. No need to clean copper that is already clean.

    I do a triple evac with nitro to remove non condensables.

    I’m feelin’ a little peculiar.

    But doesn’t it get exposed to ambient air the moment you take off the cover or cut extra tubing off?

    Also, don’t you want to rough it up a little so the braze adheres better to the surface?







  • I have an entire set of brushes for every size acr pipe. 1/4” acr up through 1 1/8. Buy them at Johnstone. They have a blue handle can’t think the brand.

  • Sure, those are common. How about the indside of a swaged fitting?

    What’s the difference between a coupling and a swaged fitting???? They are sized for the female portion of the joint.

  • Takes quite awhile to oxidize. For example, I do service work. I cut the piece I want from my roll then pull the cap off and stick it back on the roll. A matter of seconds.

    Wait till you see someone braze over heavily oxidized pipe, LOL.

    If it is soft solder or that high content silver solder, then I make every effort to get things clean. It’s faster to take the time to clean than to have to it over.

    One less chance for a leak.

    Officially, Down for the count

    YOU HAVE TO GET OFF YOUR ASS TO GET ON YOUR FEET

    I know enough to know, I don’t know enough

    Why is it that those who complain the most contribute the least?

    MONEY CAN’T BUY HAPPINESS. POVERTY CAN’T BUY ANYTHING

  • Oh yeah, I guess so. Never bought any of those brushes. Just wrapped the sand cloth around my Sharpie. Since I’m getting closer to retirement, maybe I should buy some of those brushes. Probably wouldn’t want to take the time to run back down to the truck. Roofs bigger than a football field, then all the ladder and stair work, etc . . .
