Well you want one to stay small and one to get big, if you chilled the male fitting and heated the female fittinf that would be overkill lol. Might not even need thread tape at that point lol.
I know its not needed, i just figured id go the extra mile. I keep having leak problems so i was getting desperate to make my pieces work.
Where are your fittings from? Just started a thread on this coincidentally. (Cheap parts and leaks)
ā¦Although it sounds like the solution was this tape
HFS, usually couldnt be happier with what they got but theyre current npt fittinfs just are not as hard as they were a couple months ago.
Galling and thread dulling happens extremely easily now.
Oh ya. Ive stopped going to hfs for fittings. Xtractor depots fittings are where my problems stopped. Ive had about 7 out of 8 fittings leak from my last hfs batch.
Fucking bullshit right? Im glad its not just meā¦
Ya, itās hit or miss with me when I piece something together. I have about a 75% success rate on sealing fittings the first time haha.
I literally started that thread as you did this one
Thats pretty decent ime.
Had 100% 1 time.
Usually 50% here
Usually i dont have problems but this specific build i got right now has SO MANY fucking leak points. Shoulda went compression fittingsā¦ by the way any old stripped HFS fittings can still be used for compression fittings!!!
Return them. Tell nina their site says no restock fee so dont let her tax you.
Go to xdā¦ If its not too late
Its too late for a lot of the fittings. Stripped them to hell trying to prove to myself that the problem wasnt myself.
I actually get my npt fittings from ebay, theyāre waaaay cheaper, and Iāve been extremely happy with the seller so far.

Thereās a link to one of their part, but the seller is adapters21
Donāt know what the ones you are having problems with look like but Iāve definitely gotten low quality Chinese import fittings off eBay/Amazon that are supposed to be tapered as per NPT standard, but they had cut straight threads with no taper whatsoever.
Thats what hardware factory store is currently pushing out. Threads were cut all the way through to the bottom of my end caps so the threaded hole is the same diameter as the bigger end of a 1/4 NPT tap. As a result my fittings seem to fit perfectly but will never make a decent seal.
Luckily I havenāt had that problem with this particular seller so far.
I found them awhile ago, and now buy all my fittings from them.
I was looking for a npt to flared adapter when I was first setting things up, saw the green taxes at all these places and said screw that. Did some research on hydraulic fittings to get granger part #'s and found this seller on ebay from a part # search.
Iāve posted their listings numerous times now lol, hopefully Iāve drummed up some business for them.
Just making a little contribution, i found this thread looking for answers and found it to be great.

Iāve used the yellow version of this brand of tape and it is very thick and strong, i canāt even imagine how this one will work. Amazing thread guys!
Thanks fam 
Just ordered 2 rolls myself
does the nickel ever leech into extracts?
