Too risky pal , they are for bang on 20 mm , Alkathene is about 20 mm give or take .

Bit outside the box. What about a lead-loc?

Are right, I thought it was a 1/2" mdpe to 20mm mdpe adaptor so you could then use a metric fitting to adapt to copper. That was my thinking anyway.

Or one of these?

Are you saying that one of these:

20mm MDPE x 15mm Speedfit/Copper Pushfit Adaptor

is no good because your 20mm Alkathene is really the old imperial stuff? If so, I think that 'Polygrip' is the brand you want. See for example:

Philmac & Polygrip Pipe Fittings - R J Pryce - Plumbing, Builders Merchant & Ironmongery

who seems to have a big range.
