Loader Brand of quick couplers found on Mahindra loaders?

But for now, the issue is o-rings... both at the valve port and internal to the couplers. The remaining leak is at one or the other... or both. Looks like it will be Saturday before I can get back to work on this problem.

Managed to get back to the tractor today only to find the new, slightly-oversized #112 o-ring in the recurrent problem port leaking badly. When I took it apart, it was clear that the o-ring failed because it was too thick and got squeezed to the point where it became damaged.

So against my better judgement... but consistent with on-line data... I replaced all four working port o-rings with #906 o-rings. Except for some likely residual droplets, the #906 o-rings (70 durometer BTW) are holding for now.

One thing is clear: Despite obvious signs of o-ring wear on the male tips, the leakage problem is not the internal coupler o-rings.

On the way home, I stopped and bought some #906 90 durometer o-rings. I'll try those next if the leakage reappears.

I probably need to get some of the #906 o-rings when I'm at the hardware store next, just to have on hand if needed.
