Astra 1.7dti oil cooler bypass, what pipe to use?

[fix]

The oil cooler on my astra dti is leaking oil into the cooling system, ive taken the rubber oil pipes off the cooler, but I need something to join them together.

The pipes look like they are best joined when they are next to each other so I would need a "u" piece connector but i cant find one, i can only find a silicone 10mm 90 degree connector on ebay which i dont think will work, the pipes will be too bent.

Copper plumbing pipe would probably do the job, but i dont think i could get it bent into a small enough "u" shape.

If I had the right pipe it would be a 5 minute job, but without it im stuck.

I was wondering what people normally use to bypass the cooler?


Also after reading up I see people join the coolant pipes aswell when bypassing the cooler, I couldnt see the coolant pipes going into the cooler. Do I really need to find them and bypass those aswell?

If anyone can help i would really appreciate it, i want to get my car back on the road asap

Thanks
