Anyone know what this fitting is called and if you have a part number you'd make my day? It looks some what like an air compressor coupler. I haven't messed with it as the slide still works. If seems like it is not leaking as bad as it first did, which has me thinking a dried out O ring. I can't have the slide not work and I'd like to have a replacement in my hand before I mess with it.

What you have is a two part coupler for a hydraulic system .

Part one with the knurled edges is a quick connect coupler
The other piece is a quick connect nipple .

The coupler treads onto the nipple by turning the knurled part till tight ; the internal contact point in the coupler holds the nipple open to allow fluid through .

If the leak is through the knurled portion , I'll bet it's just loose .
Wipe it down and twist the knurled tube till tight .
Once tight wash the area down and check fluid level as per the system owners manual .
Cycle the system and check for leak.

EDIT...Well Skip seems to have the handle on them if screw type I mentioned They are easier to replace O-ring in .

They are hydraulic quick connects . But there are different styles and sizes. Usually they have female threads. Some pull back like air fittings and only unlock if small cutout is lined up others the outer collar unscrewed common on porta- power kits rams.
This brand is inexpensive but but made like German engineering parts. This is just an example a forklift attachment at work has several . The OEM Parker female seem to mess up about 10 times used these are 1/4 the price and made better .

I made a quick attempt to tighten the fitting up. Nothing was lose and I couldn't get it to tighten up anymore than it was using channel locks. Once I get that done with swaping out my Nevercold, I will take this mess apart. I hope it's an O ring or something easily found.

Thank for the replies, I do appreciate it.
