I thought I would update this thread that I finally got it fixed. This is a very long story. Bottom line is that dealing with Tractor Supply has been a joke. I finally got the friggin part there. The control valve. Through many conversations with various people all around the country, I came to the conclusion that I could not simply replace a part, such as an o-ring, I had to replace the entire control valve. I was told that they don't sell parts for this. Chinese made. When I first contacted TS, a man spent quite a bit of time looking for the part. Finally got on the computer and announced very confidently that this control valve is not stocked, that it is only available online. I kept asking him "Are you sure" because in the past, I thought I had seen what appeared to be control valves at TS. He assured me those are not control valves, they are something else. Several conversations later, I finally gave up with dealing with people on the phone and went to TS myself, with part in hand. This is after I contacted three different TS stores to get somebody on the phone that seemed to know which end of a splitter is which. Anyway, went to the TS with old control valve in hand and found control valves and matched it up with my old one. It does not look exactly like my old one at all, it's made quite a bit different but it's overall the same and all of the orifices are the same. Bottom line is it worked and I am a happy camper. So far. No leaks. But not happy with dealing with Chinese stuff sold by TS. I will try to remember to update this thread with the part number. This control valve might be used on other Countyline splitters above the 25ton.
Here is a pic of the control valve box for the Countyline 25ton splitter that appeared to me to be a match. As I have reported, it is working. BTW, on the back of the box is this part number -- 310997. Tractor Supply SKU No. 1170820. Hmmm... since I had so much trouble finding this control valve (due to several instances of getting misinformation, plus the fact that I was told that this particular part can be a bit problematic for finding an exact match), am considering buying another to put on the shelf just in case it goes out in the future! And hope that I remember that I have it! Sorry, I do not know how to orient the photo into landscape mode.
While there may not be a county line part number for the o ring you could take the valve apart and go to a hardware, automotive or hydraulic shop and match one up or get a couple close and see what works. No real magic there. Even if you bought a dozen to find the right one it’s a heck of a lot cheaper than buying another valve. Just a thought.
Yawner. This is about as close as I can get to a parts list. Sorry I was late to the party. http://www.princehyd.com/Portals/0/valves/LS3000Manual.pdf
