I recently ordered a HERMS coil for my HLT, but after receiving it and the seemingly overly expensive fittings, it’s going to be a very tight fit. The fittings are much longer than I expected, and frankly, appear to be at least 1/2” to 3/4” longer than they need to be on the compression side.
The main issue is that where the bends are placed in the coil, the tubing is quite a bit out of round, so the ferrules barely fit and won’t slide very far onto the tubing, pushing the coil out even further than what you see in the second pic below.
All that to say, does anyone see an issue with simply soldering in the tubing to the compression fitting end and not even messing with the compression ferrules and nut (third pic below)? I can’t see a need to routinely have to remove the coil, and even if I did, I could simply remove the outside nut on the fitting or simply desolder it.
I figured I would ask since I could not find another example of someone doing this, and it seems to make more sense in my mind than messing with the compression fitting and possible leaks, etc. I just wonder if the solder joint will be strong enough to support the weight of the coil without cracking or weakening down the road.
