I'm trying to find the right conversion for this last part. I've already converted the dryer internally, but on the back on the dryer is a male threading that measures 1/2inch across (PIC)

And the flexpipe that I have says 3/8 nut  (PIC) The nut is much bigger than the male part on the dryer. What part on Amazon or Home Depot would help me couple these? I'm not looking to buy a $30 new flexpipe if a coupler will suffice, unless you all think its unsafe. I have proper gas taping waiting for me.

So far my noob self is looking at this amazon part wondering if its what I need, but i clearly need some help as I do not know. https://www.amazon.com/Industrial-Fitting-Reducer-Adapter-Female/dp/B07XDNK93G/ref=sr_1_10?dchild=1&keywords=3%2F8+male+to+1%2F4+female+adapter&qid=1606450984&sr=8-10

The fitting your link leads to is likely NOT the fitting you need.

Your dryer has a male 3/8" NPT (commonly referred to as 3/8" pipe thread) inlet to which an adapter has been attached. The adapter changes the male 3/8" NPT to 3/8" male flare thread to fit a smaller flex supply tube than the one in your second picture. NOTE- NPT (pipe thread) and flare thread are distinctly and deliberately not compatible with each other, hence the use of an adapter.

To connect your flexible supply tube to the dryer you would need to remove the existing adapter from your dryer inlet and install a fitting that will fit your flex line. I suspect that the connection nuts on your flex line have 1/2" flare threads (I say "suspect" because your picture does not show the inside of the nut; disregard the size stamped on the nut because that is a reference to the nominal inside diameter of the flex tube itself, not the thread in the connector nut).

You will need this adapter: 3/8" FIP (female iron pipe; or "pipe thread") x 1/2" male flare. It will look like this:

NOTE- always ensure that your flex supply line is rated for use with the fuel supply (in your case propane/LPG). Also, the manufacturers of those flex supply lines generally consider them a "one time use" product and do not recommend re-using them.

  • Thank you I will try and take all this information in. I will try and remove the adapter you say is already on the dryer inlet. I tried to when I initially did the propane conversion and it would not move at all.

  • To further detail this for future people if any, this video helped me visualize what to do concerning the inlet for the gas. A Jimmy said the dryer inlet, someone already put some sort of adapted. I didnt know this and thought thats how it was standard. Si I will do my best to remove that as displayed in the video, and put on a proper fitting. youtube.com/watch?v=d2ULPsmF3Ik
