Black Alkathene pipe

[CAESAR32]

I'm wanting to connect on to black alkathene pipe, do the still sell fittings and liners for this?

 

[kevplumb]

yes any decent merchants

 

[CAESAR32]

ok it looks about 22mm is this the standard size for Alkathene pipe or does it come in many sizes. At the moment it is joined by brass comperssion fittings.

 

[Bahco]

Its probably 17 mm so you should ask for an alkathene adapter to take you to 15 mm.

 

[CAESAR32]

are these usualy compersion with liners for the Alkathene?

 

[Elkato531]

I think Philmac do fittings to adapt from black to anything else. If you can cut a bit off and take it to your local plumbers merchants they should be able to help.

Is 17mm the standard size for this when used to supply houses?

Mine is 17 mm

Is 17mm the outside diameter?

 

[powell30]

Philmac do indeed do universal connectors....but you need the INSIDE diameter ie 3/8's 1/2 inch etc so you can get the correct insert.....they are all colour coded

 

[Fallout]

they are all colour coded. Are you refering to the universal couplings ?

 

[powell30]

Sorry....the inserts are all colour coded.....if memory serves me right 3/8's is white. The universal couplers come in various sizes.......15-25mm 20-28mm etc. That applies to the end to be jointed onto......out is 15, 22 etc

 

[Fallout]

ok do you mean the inserts to the transition couplings not the akethne

 

[powell30]

No.....the coupler has a cone shaped body which when screwed down grabs and holds any 'sized' pipe within it's size range. However to effect a seal the pipe it is coupling to needs an insert to stiffen the end grabed......get what i mean? Like pushfit fittings today have to have inserts.....

IF you are really stuck, like I have been a few times, cut a small piece of pipe and take it to the merchants to make sure I get all the right bits the right size.
