Question about a hydraulic line leak on a King Air 200 we had in the shop

We had a persistent seep on a right main gear line for months. After three attempts with standard seals, our lead, Mike, suggested switching to a specific high-temp fluorocarbon O-ring from Parker, part number 2-009. The difference was immediate; the line has been bone dry for over 60 flight hours now. Has anyone else had a similar fix with a different seal material on older Beechcraft?

Switched to those same seals on our 90, fixed it for good.

Check the line itself for wear, not just the seals.
