I have a 32mm Alkathene pipe that terminates on a one way valve on a pressure vessel.
To make the connection these is a metal Alkathene fitting .. consisting of a nut, compression Olive, space and an O ring.
The nut then screws onto the pressure vessel fitting, pulling olive tight onto pipe and spacer presses O ring into groove in the fixed half of fitting, and the O ring making the seal.
Picture here of the pipe end fittings.

The O ring is damaged .... anybody know where I can get spare O rings ... size is 3.5mm x 32mm
I estimate 3.5mm as it is different at every point I put callipers on.
The designation on the fitting is :
DVGW G.PN4 WPN10
(The DVGW tells me is is German water systems standard)
Tried local plumbing & commercial plumb centres ... all their alkathene fittings are plastic not metal ... no option to change to plastic as it has to work with existing pressure vessel.
