It looks to me like it's the 90 degree bend on yours that's leaking where the 2 plastic collars hold the pipe to the elbow that goes into the bulkhead. If you remove that and then gently use a hacksaw to cut the collars off, you can use any Xantia elbow on the V6 pipes.
The elbow on my V6 breaker split when I removed it so Robert cut the collars off, used the original TCT elbow and jubilee clipped the V6 pipes onto it
