New power Steering O-Ring broken

[Magee]

Just wondering if anyone has ever had a brand power steering O - Ring break apart after installing. For reference the car is Mk1I FG G6E. I bought a new PS hose to replace a leaking one and 2 new O-rings came with the kit.

I lubricated them before fitting over the pipes and both went on okay. After clamping down the pipes and refilling the reservoir. I started the car to bleed the system and found I had a massive leak where the 2 pipes go into the steering rack.

When I remove the pipes the O-ring on the return pipe was broken as per picture but the one on the supply side was okay. As a test I took the O-ring from the removed hose and put it in and refilled system and there was no leak.

Just to note the hose was from a major Auto parts retailer and not from Ebay.
