I didn’t get round to sourcing a pipe manufacturer yet, unfortunately the spare pipe I bought was damaged and I didn’t have the time to go down the re manufacture route just yet, just needed my car off my friends ramp and back to the road quickly. However, I think I have had a little success in resealing my existing ones, I hesitate to congratulate myself though as I’ve only been driving it fours days since, but it’s not currently leaking and every other time they’ve leaked straight away so it seems successful at the moment.
In the past I’ve tried using a set of those green crappy o rings that are available on flea bay as a boxed set of various sizes, they seem quite soft and easy to damage, when I used oversized versions of those they got pinched on the way in and the back edge of the oring recess on the pipe would cut into them and damage them, very leaky.
The original sizes of ring I think are 7.6 and 8.7 diameters and 1.8 cross sections. I found some nitrile ones on flea bay and went for slightly smaller diameter, hoping that would mean they’d be slightly tighter on the pipe and slightly bigger cross sections so they’d be tighter in the housing. 7.5 and 8.5 diameters and 2 mm cross sections. When I fitted them they did seem tight and I was worried they’d pinch and split like the green ones so I pulled them again and they seemed fine so I refitted them.

Link to the orings attached, if the link doesn’t work could someone please let me know.
I also started looking for o rings with 2.2mm cross section, much harder to find but I did eventually find some from polymax, if the 2mm ones end up leaking I’ll try them but I fear that the extra 0.4mm might be too tight of a fit.
If the 2mm do start leaking and I try the 2.2s I’ll keep this thread up to date on it, but for now the 2mm nitriles seem to do the trick.
