hydraulic. steering cylinder

If youre talking about the angled fittings then yes. They arent tigtened too tight to begin with since they both have to face the side the hoses exit the hull.

I cant imagine a set of circumstances that would lead to the cylinder end cap completely coming off without direct intervention. The seal doesnt engage unil the last thread seats, so gradual loosening isnt likely without dumping all of your fluid well before the cap fully disengaged.

It happened to me 2 yrs ago,, it dumped every last bit out!! Had to troll back because I lost all steering
