Yes the fittings to connect the lines to the steering valve. The fittings have o rings on the threaded part that screws into the valve body, then you tighten a jam nut to lock the fitting at the angle you want. You will have to disturb a couple to get all the lines off. If the o rings under the jam nut are hard, they may not reseal when you put everything back together. These are a standard size and were in my generic o ring kit. The time to change them out is when the valve is upside down on the work bench.
