What's it #2 - I found this in my tool box

Looks like a dikfer

The issue with the coupling is one end will have to screw into something that has something like a post in it to open the ball check valve on that end or pressure to open it. Then if grease was pumped into the other end, that would open that ball check valve.

Wouldn't that be a high pressure hydraulic grease fitting? Maybe not, apparently the only guy who knows isn't talking.

Does just the one end have the small bleed off hole?

The hole is drilled in one end but it enters the cavity where the spring is. That makes it a vent for either side when either ball is opened.

Can't be, I know what a diksfer.
