Yanmar Hydraulic Compression Fitting

Sold Individually. You will typically need to per tractor. 
Made In Germany. Very nice Quality. 
3/8" NPT Male Thread 

Installation Tips:
Measure your steel pressure line to be sure that it is roughly 0.47" diameter. There are some Yanmar models that have a bigger 0.55" steel line and they require a different adapter.

If your line is roughly 0.47" diameter then find a straight section of the line that is in an area where it will be convenient to hook your hydraulic hoses to. This usually looks the nicest and cleanest to plumb if you can get back behind the seat somewhere. The adapter will not work if the line is not straight for at least 3/4". Cut a section of the steel line using a tubing cutter.

Sand the ends down to remove any burrs, rust, or loose paint. 

Slide the compression fitting nut onto the steel line followed by the small ferrule and finally the fitting. Push the fitting as far onto the steel line as possible and tighten the nut onto the fitting. You will want this to be pretty tight.  

Hook up your loader or log splitter valve to this adapter using 3/8NPT Female hose fitting following the instructions below
