JNewman Posted May 2, 2016 Share Posted May 2, 2016 Well I finally got around to joining the induction club. I need to make some smaller and larger coils than came with the machine which is about 1.5" id I bought 1/4" and 3/16 copper but it looks like I should have got 5/16 instead of the 1/4" That being said has anyone tried quick connect fittings like these on their induction unit ?http://www.wattscanada.ca/pages/whatsnew/qc_fittings.asp They look like they would work well both as quicker to change not needing to flare the pipe and not needing extra nuts for every coil.

the iron dwarf Posted May 2, 2016 Share Posted May 2, 2016 dont think those fittings will work at they are not conductive ( and a lot of power goes through the coil ) Quote Link to comment Share on other sites More sharing options...
JNewman Posted May 2, 2016 Author Share Posted May 2, 2016 Good point. Anyone know of any conductive quick connect fittings ? Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted May 2, 2016 Share Posted May 2, 2016 I doubt you will find any, first check how much current is going through it then look for some suitably rated. depends on your machine but I think it will be higher than you expect Quote Link to comment Share on other sites More sharing options...
JNewman Posted May 2, 2016 Author Share Posted May 2, 2016 Looks like I am going to have to buy some 5/16 tubing and some metric flare nuts. Quote Link to comment Share on other sites More sharing options...
Will. K. Posted May 2, 2016 Share Posted May 2, 2016 I think Grant Sarver talked a little about this in one of his posts on induction heaters. I've seen some where the coil tubes go into copper block connectors that are held together by some sort of insulator, these get pressed against similar block on the unit with a screw clamp. I beleive this is the arrangement on some of his induction units you can see in his videos on YouTube. I recently missed out on an auction for an induction unit that had one of these quick connectors on it. I will PM you the link for the completed auction so you can take a look at the pictures. I do not think I can post it here per IFI rules. Quote Link to comment Share on other sites More sharing options...
JNewman Posted May 3, 2016 Author Share Posted May 3, 2016 Thanks Will. That looks like a good quick change setup but more involved to make new coils rather than simpler. I am going to stop today to see if I can pick up fittings to adapt the metric to 1/4" flare. Quote Link to comment Share on other sites More sharing options...
ianinsa Posted May 3, 2016 Share Posted May 3, 2016 I've found it easy to get the flare nuts front a/c supply places , then buy two bags full(20_24) and Tada happy camper fill your copper tube with water, stick it in the freezer overnight and make coil. Flaring tools should be cheap from HF and/or motor spares shops. Regards Ian Quote Link to comment Share on other sites More sharing options...
EricJergensen Posted May 6, 2016 Share Posted May 6, 2016 You're looking at 800 amps probably (the LH-15a does 800 amps). Get the 8mm flare fittings. Your water cooler is probably already lower than your induction heater, but just in case: if your cooler isn't lower than your induction heater, coil change will be a wet mess. P.S. I would expect that any quick release fittings would basically weld themselves together! Quote Link to comment Share on other sites More sharing options...
