I have a leak on the Nimco FEL control valve below the joystick. Is there a gasket attaching the silver box at the base of the joystick (to the black casing)? And is it easy to replace? Might it be an o-ring on one of the connectors that’s an issue? I see no leaks around the attached hydraulic hoses.

I suspect there are O-rings around the spools under that silver cover. Possible they are in a counterbore and held in place by that cover.

Looks like its leaking from the spool. The oil dripping is an issue for your footware. It will destroy the bonding between rubber/leather.
The plate has no gasket. It holds in an O ring at the end of the valve spool. There are 4 O rings total, 2 on top, 2 on the bottom. I got mine off ebay.

O ring size 13.3 x 2.4mm

Just a side note here. Does the valve have six lines or seven? If it has six, replacing O rings will only be a short lived fix. They will start leaking again at some point.
It has 6!!
Thanks. Would these be the right ones? 15pcs Black NBR70 O-Ring Washer Sealing Gasket 13.3 x 2.4mmâ¦KD | eBay ? Is the install relatively easy? Why would the loader need to be removed?

With only six lines you will be doing this again. Better order some extras to have on hand.
Am looking at a 15 pack, if they are any good. See my reply to DMW.

Good plan. That should hold you for a while.

They will work. I used Viton®/FKM O-ring 13.3 x 2.4mm 5 years ago, no issues. They were 10x the cost but have worked. Ordered a set of the cheaper o rings (like your pic) at the same time just in case, but never had to use them. The first time I did the repair used one of those multi-size 100pc o ring kits, didn't last a day before they blew.
