Leaking Rangie auto oil cooler pipe

Suffered a leak from the bottom pipe on the auto box last year and had it replaced with an expensive genuine LR part as it was in the garage for something else. Part lasted two months then poured oil again. Part replaced under warranty. Lasted 4 months until it started leaking again at the start of a Land Rover run. Replaced myself this time with a part from a breaker but don't like the joint with it's little 'o' ring. Just found out a friend has had the same problem. Having a part made up with a proper hydraulic fitting as I don't want to keep buying a poorly made and expensive Land Rover product which could leave me with no gears doing 70 on the motorway! Anyone else had the same problem?:rolly:

ive heard a rumour that if you take the pipes to a good hydraulic hose place they will make you a set up. i think they use your ends tho
