Leaking Hydraulics

I have an annoying small leak on a hydraulic connection on the loader valve for an IH 434. Is there anything that can be done to remedy the situation short of replacing one or both ends?

Or; if you need to replace them; Here's a link https://www.amazon.com/Hydraulic-Connect-Tractor-Couplers-
Pioneer/dp/B08CDCG2NT/ref=asc_df_B08CDCG2NT/?tag=hyprod-20&linkCode=df0&hvadid=459. Less than $30 for a set of two. I recently replaced
some on a John Deere loader.
 
You can try replacing those O rings.

Finding good quality rings the right size is the challenge. Lot of cheap rings out there.

And the durometer (hardness) of the O-ring material is often 90 for those O-rings.

Yes I did try swapping out the O-ring for one in my box of cheapies, but even though the diameter was correct, the thickness was not, and it also leaked. So I put the original O-ring back in, but I flipped it so the slightly flattened side was on the outside of the ring. Testing so far shows it does NOT LEAK, but I shall monitor it when under a heavier load.
Thanks for the responses.
 
An elbow on the valve for the couplers to set flat with the loader frame would relive side ways pull on the couplers. That in turn would let your o-rings last longer and be easier on things in general. new couplers are not that expensive if you need them.
