JIC fitting size?

[Gregster613]

Wow myyaz33, Sure am bummed that those fittings didn't work out. I've been following your build threads closely - Absolutely a work of "Art" is your grapple build!! I am going to need to figure out those fittings also when I get around to putting on a diverter valve - so I'm very interested in what works out for you. Wish I could offer some advice - but, alas I have none. Good luck in your hunt and please continue to keep posting your steps.

Thanks, Greg

I already have a caliper so now armed with the knowledge, I can find the right size the first time.

Yes you should - keep in mind that area of a circle isn't linear relative to diameter - if you reduce diameter by 1/2, you'll get 1/4 the flow at same pressure. Looking at your pics, I'd guess the flow difference between the two would be just about DOUBLE... Steve

(a diameter change of 1.414 up or down is double or half the area)

Yes, but the joint itself is only a portion of the pressure loss at flow. Doubling the pressure loss at a joint does not mean halving the circuit flow. Flow may not change at all. It will surely make the pump work harder/nearer relief pressure. With full load and speed it may cause some relief. This wasted flow/relief will reduce implement speed some.

First off, I wanted to thank everyone for the help and input here. Very much appreciated.

Now onto progress.

Basically everything I did so far with ordering what I thought was the right size and then remeasuring the same fittings, was all for nothing. What I mean by that is the fitting I was using to measure with was a fitting that went directly into one of the curl cylinders. Guess what?, that fitting is not the same size as those that feed the line and I just assumed on my visual inspection they were all the same. Even if I would have got the right fittings ordered for my first set of measurements, it would have still be wrong.

Anyway, here are the measurements for correct fitting that will be used.

Dimensions for fitting that feeds the loader (will be used to tap for diverter solenoid valve)
ID- .504
OD-.558
Thread- 18
Flare Angle - ? (I don't have a gauge)


I believe this is JIC-6 but hoping someone can weigh on a quick way to verify flare angle?

Check all the way thru on the link in post #2. It seems your measurements match only JIC-6. ... Maybe draw the angle with a protractor and compare. Different types vary by several degrees. Enuf to tell.

I went through that guide for about 2 hours.. Another order has been placed. Hopefully everything is all good now.

I believe kioti and TYM have there loaders built in the same factory and my Kioti loaders uses all -5 JIC. (very uncommon). Maybe you should just order a -5 and a -6. Fitting are cheap... Good luck.

I believe you are correct about TYM and Kioti loaders and think Tae-sung was the manufacturer. I found both -5 (on cylinders) and -6 (on steel tubing) on my loader. My mistake will cost me over $100, so cheap is subjective.

Not correct at all. The dash size refers to the inside diameter. Kinda hard to have a 5/8" inside diameter with 5/8 outside fittings.

A 1/2" fitting (-08) has 3/4" threads. And 9/16" threads = 5/16" (-05) fitting. (there is no -9 fitting BTW)

I apologize then you must have different sizing in the US to us over here then

Final confirmation on the TYM LT200 loader that they were indeed JIC 6 fittings that I needed for the steel tubing. However do note that there are JIC 5 on the cylinders themselves.
