Looks like I buggered the o ring on one of my couplers, that hose leaks bad now. Is the o ring easily replaced or am I better off just getting a new female end?

Most are a simple fix, it's finding the right O-ring is the problem.

I’ve had to replace one of mine and it irritated me to replace the whole fitting when all it needed was an o-ring. After much searching, this is what I found for Pioneer couplers and it’s worked for me.
1/2” Pioneer: Size 117. Hardness 70A (medium)
3/8” Pioneer: Size 115. Hardness 70A (medium)
1/4” Pioneer: Size 113. Hardness 70A (medium)
Pioneer sizes weren’t intuitive to me. There are numerous size charts online. Example:
Flat face, I have no clue but looks like you’re dealing with Pioneer.
Edit: Should have stated material: Buna-N.
