Hydraulic Fitting Question

[ETpilot]

Yesterday I made a mistake due to a dumb field mouse. I had my FEL with forks pointed down searching for wood debris in tall grass. I saw this mouse and sort of chased it along my route. Well the forks struck high ground and the bucket rolled to its limit causing the tractor to slow. I immediately raised the bucket and rolled it but I saw fluid spraying all over. I just shut down. Turns out one of the roll hoses rotated and it created a hole in the hose.

So I took the hose to NAPA and they made a new hose. I also kept the old hose. When I was ready to install, I checked one hose against the other and found the size of the new fitting different from original. Original fitting has a 3/8 opening. The new hose fitting has a 1/4 opening. This will, I imagine, cause a disparity between the 2 cylinders and may cause a problem due to flow rate. So I need opinions on this. New hose is not installed. I may have to take it back. The picture shows the different sizes.

I suppose the right fitting on the picture is the old one, right? If you look deeper, the hole starts with 3/8", then it goes to 1/4". Just different brand fittings, machined slightly different. I think it'll be fine.

The more immediate problem is the one on the left LOOKS like an ORFS fitting and the one on the right LOOKS like a JIC fitting.

That's what I thought too, first one ORFS, second one a little harder to tell for sure, not enough contrast, but I still think JIC.

1/4" ORFS has the same size threads as 3/8" JIC

If that is the case, take the hose back and get one made using the correct fittings. On their dime.

I’ve made a couple hoses with wrong fittings in my day.

With the reflection it’s hard to tell if they are the same type of fitting- they probably are. The flow difference between the two won’t make any difference on a CUT. Plus the old one has a step down in size that looks real close to the new one.....it’s negligible.

I think its just the lighting. But as to the hole size, if they are indeed the same and both JIC fittings, there is no issues at all

Thanks for the replies. This hose is for the roll cylinder on a Ford 7210 loader. After reading the replies I took another closer look at the hoses. Definitely not an ORSF fitting. I had to look that one up. No O ring. New fitting is a flared fitting, JIC.

Using a transfer punch I measured the port opening. New fitting definitely 1/4 inch opening, hose is 3/8 inch. Old fitting has a 3/8 inch opening. Using the transfer punch a 19/64 inch was the only one I could get inside. Only a .0468 difference from 1/4 inch. Best I can figure. So flow wise I may be ok. In any event, I am taking the hose back and see what they say. I am probably ok with this hose.
