What kind of valve is this exactly? Never seen that exact connection type

I’m pretty new to this. I was considering replacing it with something else because it leaks slightly from the valve if it gets moved around at all, but I don’t know what this connection is to start with. It goes to a dishwasher.

Yours has a different crimp style, but its a 1/4 turn shutoff valve with PEX crimp. Looks like standard builder quality.

  Oh, that’s a PEX crimp? Does it have a specific name? Most of the PEX crimps that I’ve found have looked very different.

    The crimp style shouldn’t matter. Use what you can get that fits 1/2" pex.

Sorry, could you provide a little more information? You say it leaks from the “valve”, but there are 3 different places it could be leaking from, and all are part of the valve – the valve being the whole device from pipe to pipe.

If you’re thinking of replacing the whole thing, I’d focus more on the type of pipe, which looks like Pex coming from the house, and probably some sort of standard dishwasher feed line on the other side.

Ideally you could buy a replacement valve before starting the project, but you might have to remove this valve and take it to the hardware store to make sure you get the correct thing.

I’ve never worked with Pex, but I believe you can either crimp it with a special tool or use the sharkbite system.

  Unfortunately is has stopped leaking for now. I say unfortunately, because I don’t know when it may start again. It seemed to start to leak when I pulled out the dishwasher, so movement/flexing/etc made it happen. I was unable to determine exactly where it leaked from, but it seemed to pool near the center of the entire valve, so it could have been near the crimped area or the knob area, or maybe even the connection going off to the dishwasher, and the water could have just run down to the lowest bit of the valve.
  
  It’s 1/2" nominal PEX going to a quarter-turn shutoff, to a 3/8 braided dishwasher line. I just didn’t know what to call the weird crimped/connector part on the PEX, and thus how to properly remove it if necessary. All of the PEX crimps that I’ve found online have been very different looking.

    Micro leaks can plug themselves with time as calcium builds up.
    
    The easiest fix to that is just a sharkbite valve since its accessible and visible. Probably 15 min job.
    
    Or you could go with the pex clamp route but that requires a special tool.

    I agree it’s an odd looking crimp, maybe just an older style of what we have today. I’d guess that’s the last likely thing to leak.
    
    Best case scenario the dishwasher line just needs to be tightened. Worst case you can replace the whole thing with a sharkbite type valve, but you’ll probably need to cut back the previously crimped section of PEX (note: I really have no clue about that).

I’m guessing it’s a right angle quarter turn ball valve. It’s crimped on one side and looks like a compression fitting on the other. Maybe it’s a gate valve, which in my experience are far more prone to leaks, but the notches in the handle make me think ball valve.

Which part leaks?

It’s an angle valve for sure, but it looks ancient. Nowadays the valve would be inserted into what looks like pex piping there on the right, and you crimp a ring over the piping to get a nice tight compression fit.

  The house was built 7 years ago, so maybe the plumbers just threw on whatever they had in their van. Do you know what the crimped method/area is called on this thing? Is there a specific term for it?

    They’re usually just called “crimp rings” or “cinch clamps”, the former being the more popular term in my experience. They do require a specific crimping tool, but if you go to your local home improvement store they usually sell a kit that includes the tool with rings, and possibly even a PEX cutter.
