PekkaNF: I made a custom flexible boot for the hot block on my 3D printer using some high-temp silicon RTV gasket goop in a 3D printed mold. The kind of high-temp gasket goop that you can get at any auto parts store. The boot has been in use for a couple of years now and has probably a couple hundred hours of use on it with no issues. My printer's not as nasty of an environment as a welding gun, but something like that might work for you as a consumable. (You can always make a replacement when it craps out.) The mold parts only took a couple of hours to print and making the actual boot only takes a couple of minutes, of course you've got to wait overnight for the RTV to cure. Don |

Thank you. That is a very good idea indeed. There is a high temperature caulking for fire place use. Wonder how that could compare to RTV silicon. |

Really, all the silicones are good to high temp... some are more oil resistant, though. Fluorosilicone is more oil friendly, if I remember. I suggest diluting silicone caulk with paint thinner and soaking it into fiberglass. Then, smear more silicone on and wrap a few layers around the nozzle. Sent from my SM-G892A using Tapatalk |
