thread adapter

I can sell you a 3/4"-16 tap and a suitable tap wrench.

Uh hunh.

Very modern of you, crying about needs. Speak practically. You want someone here to make this for you, you want to know where you can buy it off the shelf, what?

Idiot . So what , you want one of us to whip you one up on our lathe ? Shop time here (my little shed/shop) is 75 bucks an hour , I estimate 12 hours for your little project . I'll get started as soon as I get the 50% deposit ...

Yeah, I can't imagine why he didn't jump at the chance to buy a tap that'd put a 3/4" thread in a 1" hole...

Yer an idiot too . Or maybe just a functional illiterate .

And I quote "I have a filter mount with 3/4" - 16 threads and a box of diesel fuel filters with

Sounds to me like he needs some internal threads 3/4"-16 , and a tap will surely do that ... But I was referring more to his attitude . Just what action did he expect from those of us who read his post ? My offer of shop time stands ...

I think that he could do something with a 3/4-16 tap, indeed. It is tricky, though, the adapter would have very thin wall.

And I wonder what the flow pattern is thru the filter . Likely that is the inlet , outlet is outside that diameter . Means that the adapter would have to be no longer than the original mount threads or the sealing surface would not work out . Kinda like an oil filter mount . A lathe would do it , if the operator were careful . I think he'd be better off ebaying these filters and getting the right ones for his application .

I want to know where I can buy it off the shelf. After I posted I found out perma-cool sells some products that include such an adapter. It's too early in the morning to call them right now, but I will find out if they sell the adapters individually.

you're so smart

Smarter than your answer - so helpful!
