Thanks! DSE never said try a O-ring I took it upon myself to give it a shot. And......woke up this morning to a small amount on the garage floor. It's not the best pic but you can see how the O-ring has torn some. I made sure the O-ring was wet with oil and it still damaged it.........ugh.

There should be a washer between the fitting and o-ring as far as I know.

Google 9/16-18 ORB and you will see fittings with washers.

I'm getting conflicting info about what material should be used, how tight it should be and weather or not to use high pressure hydraulic thread sealant (Loctite 545).

I think the rack is made for an ORB fitting but, the Stat o seals work too. Parker makes them(and others). The crush of the washer and seal of the rubber is good. If it is steering fluid, I would use a Viton o-ring material. It is strong enough for some real harsh chemicals.

I know its suppose to be a dse rack, but I just looked at your pic again. Are you sure it doesn't use this style fitting?

Yeah, I asked about that. They said nope it’s the.....ORB?

I think I got it licked now! I went to a hydraulic shop and he had a better rubber O-ring and it seems to have worked. I put a few miles on it today and all seems good!
