Please help what type is this thread is it!????

[Alex GM]

Hi, I just get this air receiver but I have 2 welded pipe on which is impossible for me to find out what type is it
Thanks all help

Looks like either 11/4 or 11/2 bsp (I would say 11/4)

And you will need a female iron if you want to use copper

 

[Alex GM]

Thanks. I would to block this out. Not in use. But any end cap which I bought is not much 1-1/2 is spinning the diameter is 1,5mm bigger and the rest is to small.

What was running into it originally

 

[gmartine]

Weld it up

 

[jtsplumbing]

I don't think its a thread ! thats some sort of push fitting, Proberly held on with a clip or grub screw

Have you tried an 11/4 nut

 

[Alex GM]

No, I didn’t try any none metric. Can you tell me please wher I can look after 11/4
Thanks

 

[Gasmk1]

it looks like a split union would fit onto it.

 

[Alex GM]

I try the split union, and was the same then the end cap unfortunately can’t tighten

Do you mean 1 inch and quarter? That’s to small

 

[Alex GM]

May this help anything .....

dont know what you mean if the split union nut fits on then thats what you nead a flat faced split union. then the cap or plug will fit into the end of the split unionhttp://www.nero.co.uk/Catalogue/150LB-BSP-Threaded-Fittings/Union-Flat-Face

What about a tank connector?

Do you think this is work? So the thread on the tank is “LB” and this conver to BSP metric?

Tank connector??? Can you please show me what do you mean?

do you have anyfittings from where you got the separator

Contact Jerome and quote the serial number, looks to me like a specialist connector.
Don`t understand why you want to blank it off but that is your business also be aware that it is 18yrs old so if you are going to pressurise it I would pay to have it tested first.
Wouldn`t play with a 216L pressurised tank with a test pressure of 25 Bar unless you are 100% certain.

Pick it up around Paragraph 19.
@ShaunCorbs
Please treat it like any other unvented tank Q and lock it down now.

According to my BSP data the dimension over the threads (which you calipered) is 1.66" for 1-1/4"BSP, 1.88" for 1-1/2"BSP. Yours falls just about in the middle! I wasn't aware of a 1-3/8"BSP, but trying metric pipe thread on the web that size is shown. Metric pipe thread is of course based on BSP, though they give it names like G1, R3/4 etc. That might be it, but if it is, I think you'd have trouble finding a 1-3/8"BSP female fitting.
As somebody suggested, it might be part of a threaded union, but checking on the Nero site, it only gives the end connection size, not the dismantleable part. That might be a BSP thread, but it could be something else, it obviously doesn't matter as you normally have both parts. It looks as if a nominal 3/4" union would have roughly the dia you need. It might be worth getting say a 3/4" and 1" union, on the understanding that you can take one or both back if it doesn't fit. Screwfix do that I believe.

Oh great, so we`re still giving advice on an 18yr old air tank with a test pressure of 25 Bar that somebody has acquired not knowing if the pressure relief valve works or is even there!
