 Posted: Wed Jul 16, 2008 2:30 pm Post subject: Blanking off T piece |
  |
|
|
Hi,
I have removed an existing shower and installed a new one. I now have no need for a feed from a T piece from cold outlet in the attic header tank.
I have tried to blank it off with a 0.5 inch blanking cap from a plumbers merchant but what I find is that I have run our of thread before I am happy with the tightness.
The fibre washer is present and to try and improve things I have put some PTFE (plumbers tape) around the thread, but it still looks as if I have run out of thread on the male.
I have left it over night with 2m head and there is no weeping.
I have tried to attached a picture of the T piece without sucess.
Should I leave the blanking cap alone now?
Thanks,
Peter

A pic would be nice of the Tee and cap.
If you click on reply at the bottom there's a box where you can browse your computer for the pic, click on open add a few words and submit.
The pic should not be too large

The tape is doing nothing but if it don't leak leave it, I assume you have a blanking plug in the fitting

The brass fitting that you can see on top of the white tape is a cap, will take picture from another angle to show this later.
Thanks,
Peter

RIght, I thought you had an Conex S61 blanking piece, a lump of brass that goes in the fitting and tightens up using the existing nut.

| It's a Conex 63B and should have been used with a Conex 98 (a rubber washer).

Perfectly correct Stoday, except the 63b is complete with the washer and the 98 is a spare washer.
The 63b blanking piece is a better fitting in that it fits all brands an not just Conex

No more likely to leak than a reducing socket + the pipe would probably be too short so the OP would need a socket as well.
The Conex blanking disc would have been the easiest fitting to use, but not everyone knows what is available.

That's a 63b Peter, they don't make an 372
I assume everything is dry in the camp

Scruff,
Is there an online catalogue that I can look at for the part numbers you are using. We are the imperial size fittings here, such as 14.7mm against 15mm.
I am looking at the Sanbra Fyffe one:
http://www.sanbrafyffe.ie/products.html
under Instantor Imperial Fittings top left corner, direct link http://www.sanbrafyffe.ie/pdfs/01%20imperial%20fittings.pdf
They call it a 372 and this is the only information that I can go on.
Elsewhere under Metric Instantor Compression Fittings metric fittings they call it a 472 link:
http://www.sanbrafyffe.ie/pdfs/04%20metric%20fittings.pdf
Many plumbers use the 15m on 14.7mm pipe and tighten the hell out of it to get the olive to give a water tight seal. I am not really happy with this.
Still dry!
Regards,
Peter

Hang on I'll have to change computers and I'// post the link for you.
What we do with imperial pipe is use the normal metric fitting and change the olive.

You should find the technical, product list and price from here, if not shout.
Look at the S 61 which would have been a better fitting for you.
