What's This Fitting?

[Iplayfarmer]

As long as you have a caliper and a thread pitch gauge we can make this easy.

I've got the caliper, but no thread pitch guage. I can measure and count, though. Maybe tomorrow after work I'll run out to the shop and get that pipe O.D. measurement that you suggested.

The pipe OD is 0.59" or 19/32". That would be 15mm which corresponds to the 15 on the flange fitting in the second picture. I think Wayne County Hose was right that it's metric.

There were 7 threads in 0.40" measured peak to peak. That makes 17.5 threads per inch.

I didn't see any markings on the outside of the pipe other than the "8 15" that was on the compression ring shown in the original picture.

I went to the other end of the pipe and disconnected it from the pump. There's an adapter type fitting on the pump that's pictured below. The pump side has the O-ring and it's 0.65" diameter to the outside of the threads, 0.61" to the inside of the threads (i.e. measuring to the valleys and not the peaks). The ID of this end is 0.30". There are 5 threads measuring 0.27" peak to peak making 18.5 threads per inch.

The pipe side of the adapter is the same as what's under the tractor. Would it be easier to tie into the hydraulics at the pump rather than under the tractor?

Looking at the picture on the right, that is definately 24 degree metric. The other side of the fitting is O-ring thread. It would be easier to tie into the o-ring thread than the metric end, cheaper too.

I like cheaper and easier.

What size would this one be? I looked on Surplus Center's website, and I see 4M, 6M, etc.; but I didn't find anything to indicate how I would know what size this one is.

I should go to the other end of the tube now. It may be cheaper and easier for me to just go rubber hose all the way. The other end is a banjo fitting. I'll get some pics and measurements.

DHH has some charts, but I did not see anything that exactly matches what you have.

I looked in my catalogs and didn't see anything either. Go here, Distributor Locator, locate a distributor. Take your lines, fittings, banjo bolt, everything to a distributor and tell him what you want to do. Banjos are either metric or BSPP but yours is almost definately metric. You can get a port adapter to go from metric to JIC and eliminate the banjo. This should all be easy for a good counterman.

Just my luck it would be some oddball or newfangled deal.

I would check the accuracy of your caliper. it's definately a metric fitting but even your ORB fitting measurement was off.

Well, it turned out being neither cheap nor easy. I bought a whole section of hose with fittings and quick connects. I took the pipe and the little adapter piece into the local hydraulic place. It took an hour and $96 for the piece in the picture.

To their credit, part of that hour was my trying to decide from the options they were throwing at me what might actually work. I ended up deciding to just leave the little adapter piece in the pump and have the metric compression ends on either end of the hose.
