Ford 550 hose leak.

[crofter 65]

Hi I have a hydraulic hose connection leaking on my Ford 550 digger This is at the valve block, and I was wondering if anyone knew what Seals this, is it an o ring or a dowty type washer?
Thanks,
Ronnie.

Looking at both front and rear valve block diagrams in the CNH parts lists,there doesn't appear to be any dowty washers anywhere. All o rings and seal kits(I'd think rotary type seals).

Thanks Agrimax, I forgot about the CNH Parts site, its been a while since the old girl has had some attention.

Those had ends that could swivel when not under pressure to allow for side shifting stresses, so it could actually be the hose thats leaking

JIC thread fitting on these things mostly which are o ring sealed on joints
