Accumulator Fittings?

[NorthwichTrader]

Hi, would one of these

 

http://www.jabscoshop.com/pressure-systems/hep2o/5mm-pipe-fittings/hd25b15w-straight-tap-connector-15mm-x-bsp.htm

 

fit one of these

 

http://www.jabscoshop.com/pressure-systems/fittings-accessories/accumulator-tanks/cw288-accumulator-tank-8-litre.htm

 

Any other suggestions for getting this tank to 15mm hep2o otherwise?

Many thanks,

Stuart

Possibly. Otherwise something like http://www.plumbingplace.co.uk/hep2o-hx24-15-brass-adaptor-15x3-4-white.html sealed with ptfe or plumbajoint.

I reckon that would do the job.

Another way would be with a 'flexible':

http://www.screwfix.com/p/wras-hose-15mm-x-3-4in-x-500mm-x-10mm/65966

http://www.screwfix.com/p/wras-hose-15mm-x-3-4in-x-1000mm-x-10mm/31385 (tooo long?)

 

15mm compression end is a little cheaper and should go OK onto 15mm PEX pipe with a pipe insert and copper olive.

 

cheers, Pete.

No, don't try anything with parallel threads that you attempt to seal with either PTFE tape or a jointing compound.

 

Best to leave that to sealing taper threads only - just don't ask me how I know this, though!

 

When I raised this before, I was assured that a tap connector was the way to go, (the seal then being to the flat end of the accumulator, with a washer, not by attempting to seal the threads.

 

Using a flexible tap connector as per smileypete's seems the way to go - and one day I will go back and change my own bodge, but probably not until it starts leaking!

Many thanks all!

Why the odd sizes on the screwfix flexies? 13mm, 10mm, I didn't even realise you could plumb in these sizes?

I guess flexi would help with the vibration factor, I'm liking that factor a lot!

Thanks again!

That is pretty much the approach I had to take to the calorifier connections, which were parallel and too big for tap connector-type fittings. I agree it's not the best option though.

Yes but the spec of the accumulator says 3/4" BSP, so tap connector should fit it.

Agreed.
