1 3/4" thread.

[Axel]

Hi.
Does anyone know where I could buy a fitting with a male one and three quarter inch thread that will reduce in to something more regular?
Google search doesn't work as it gives me 1" and 3/4" results!

Thanks Dan, but it's a male thread I need. It is a female thread that I want to connect to...

 

[Jackrae]

If you don't mind me asking :-
How have you established it's a 1.75" thread
Is the socket that you are fitting into parallel or taper
Is it "brass" or "iron"
Do you want a brass or iron adapter
What is "something more regular"

 

[Axel]

I measured it. Also it is described as that size in literature.

It is steel.

Wanted to fit a tapping or 2 onto a direct Megaflo....

The usual way that I would have dealt with that would be a 2" to 1 3/4 bush as 2" fittings are pretty standard.

In theory I might well have some.

But finding anything is always a pain.

A 1.75" bird in the hand is better than 2"bush..!

No doubt you have some kind of "shed" where such obscure fittings are comfortably nestling...somewhere..!

 

[Agile]

Sheds I suppose.

But not well organised.

I am not sure they are very obscure.

Would expect those who do commercial use them all the time!

If you need to search for something like 1¾ use the ALT button hold it down and type 0188 for ¼ 0189 for ½ or 0190 for ¾.
Check you num lock is not stopping you from typing numbers. Lots of options like 13 ♪ 14 ♫ 5 ♣.
I think it possibly only works on keyboards with a separate number pad on the right.

 

[Dan Robinson]

Or put 1.75 into the search box

Oops?

Have you just measured the threads?

BSP pipes are called according to the INSIDE diameter of the pipes. I suspect you are dealing with a 1.5" male iron.

Crane apparently still make maleable iron fittings.

My Father worked at Crane as a graduate trainee in their drawing office for a couple of years. He took me round the foundry when I was about 12. First time I realised molten brass was green!

 

[Jackrae]

Is the literature British, American, European or elsewhere.
Might sound a bit picky but thread form and pitch for the "same" size are different depending on where the equipment is from

 

[Axel]

It's the Megaflo immersion thread. 1.75" says the maker, plus I compared with bsp size chart to nearest mm.

 

[footprints]

Arr canne be doing wi that foreign stuff! I gets me decimilating points all mixed up from time to time. Never mixed feet up with inches but measurements for a room expressed in a massive number of mm what's all that about? It be like 'aving to put 25 pesos in the slot of your shopping trolley!

 

[Agile]

Try asking Megaflow where you can get the fittings from!

After all they make it!
