It is Cenex Indol ISO-VG 32. There are fittings that go into the chinese loader valve that chronically leak, even with new rubber sealing washers. Hoping that some “pipe dope' will help. Just didn't know what was compatible.
Yes I have used the captive on the steering cylinder with success, but not able to find them for this area. Do you have a secret supplier ? The “Leak Lock” I have used in the past for steam boiler fittings and like it. Was unsure about using it for oil. Thanks again Bob.
