New button housing/ cleaning threads

[Mbsun]

I am struggling with my purge tube mod, i can't get the "button housing"? If that's what it's called to thread in nice and smooth like it used to.
It does go in and create a contact but it's taking a lot of effort. (And I mean a lot)

I have tried wd40, I have had cotton wool with diluted washing up liquid on the threads of the mod, on the button housing and degrimed it quite a bit, but still no, sticking something Rotten

Any advice, alcohol? Vaseline?

Other option is buy a new one? But where from

Fwiw the mod width is 31 mm, and the smaller part of the thread is 25mm, so say 26 on the button housing

3 in 1 oil - apply a few drops to BOTH threads (or any motor oil), rotate so a little oil coats the entire thread.. Screw in A LITTLE, unscrew, rinse and repeat. Go an extra turn each time.

Wipe the mod clean afterwards, but LEAVE A LIGHT COAT OF OIL ON THE THREADS. And don't overtighten when assembling.

(and be carful not to cross-thread the bugger...)

Peek polish. Don't use oil, that's just stupid.

At a push use brasso.

Try looking at the recommendations for maintaining the threads on AV Mods...

If you're trying to force threads to re-cut, polish may do it but oil will also lubricate which makes life easier.

Always used Servisol switch cleaner. Great stuff.

The insert is not metal, it's plastic/delrin /whatever. The brass button then fixes to that (it screws/bolts in)

So I guess you mean, using the insert with polish to recut/refine the threads
Which I then assume is a no as not metal to metal?

Which one is it? And is it a clone?

Shintaro, I don't think so, and if it is I don't want to know lol

Fwiw I feel the mod is right but I don't know about the button

Anyway, oil ain't working

So a thought popped into my head, worked perfect in winter, but getting problematic in warm weather, especially last 2 days.
Also its my favourite mod, hits instantly, so I leave it in my truck while I am on site. It is red hot when I get back in.
Maybe the 2 different threaded materials are expanding differently? So I bobbed it I the fridge for 10 see what happens

I assumed you meant you were having problems screwing a brass housing into a brass tube,

The only Purge Mod I have with a plastic insert that screws into a button is an Enforcer - but the threaded part is a brass pin that goes through the plastic so everything that screws together is brass.

Can you post a pic to clarify which parts are difficult to thread because there are a lot of different Purge mods.
