What's This Fitting?

[Iplayfarmer]

What is this fitting called? It's the pressure line on my Massey 1215.

The OD on the male threaded portion is 0.80". The male "flange" fitting on the right side of the picture is 0.67". I need adapters to get from these fittings to the 3/8" NPT hoses for my loader that I am adding to this tractor.

That is some kind of compression fitting...I doubt you will find a "off the shelf" adapter for it. Try PM'ing Wayne County Hose

 

[CCWKen]

It's called a union but it's probably manufacturer specific and as Kenny said, I doubt you'll find a Tee off the shelf to fit. I'd be more inclined to leave the union in place and tap the line for a stock fitting. A flanged bung (or fitting or tube) could be brazed to either side of the union. Put it on the side that can be removed the easiest.

Swagelok Products including Fittings, Valves, Tubing, Gauges, Modular Systems, Alternative Fuels, Sanitary, Plastic Products

Check out these type of fittings. Be aware that they come in many different pressure/service ratings and configurations.

Probably best to be sitting down when a price is quoted.

These look standard connectors, with a V-ring that wedges into the pipe when you screw it tight. Most of these V-rings are standardised with the pipe sizesand differ just a little, but are compatible most of the time. The threaded ends are the ones that differ in metric and imperial. This doesnt look like a conical gas thread to me...

If you measure the nut size (wrench size) thread diameter and the length of a given number of thread windings (as many windings as possible, dividing the total length by the amount of windings you've measured, makes your thread winding measurement a lot more accurate) you should be able to determine which size it is.

.8 inch is 20.32 mm, standard metric size would be M20x1.5
the .67 flange would be 17.018 mm


edit: It looks like i read "15" on that V-ring, which makes it an oil pipe with a 15mm inner diameter, which is AFAIK compatible with 5/8 inner diameter pipes...
Comparing this to the sizes you mention, i dont think this 15 means the diameter in mm... ???

edit again:

is it this fitting ?? http://www.kramp.com/shop/action/itemcat_30_-17_10351_230646_18001_GS108L+Koppeling+10L++8L

Measure the O.D. of the steel line. If it is an SAE size, fractional, then it is called an Ermeto compression. they are a high pressure steel comnpression.

If the tube measures a metric size, then it is a metric compression. But, it could be a metric light or a metric heavy thread. If it's a pressure line, it's probably heavy thread but I wouldn't bet the farm on it. Most metric nuts will have a number and a letter on them, the number will be the metric size and the letter will be an L, which would stand for metric light, or an H or S which either would be for metric heavy. Check here, Eaton Product Literature Library > Fluid Conveyance > Weatherhead on page 145 for Ermeto compression dimensions and on page 315 for more on Ermeto. Check page 309 for metric stuff. Unfortunately, Weatherhead is a little behind on the metrics, I get them from Tompkins.

My initial bet is that it's metric.

www.tompkinsind.com is the Tompkins catalog. It looks like you will need an 8300 series fitting if it's metric, on page 136.

I am by no means a hydraulics expert, but i know some experts who can tell you which fitting it is, when holding it in their hand...
But judging it from a photo would be very hard, even for an expert...

looking at the photo, i think i read OD 15 ?? outer diameter 15 ??

I assume the part of the oil line, which is visible in your photos on the right, runs to your oil pump ?
Maybe you can undo it at the pump, and take what you have, as a sample to your hydraulics shop ?

I think that's where I'm at now. I've about given up on the easy fix option.

Once i brought something to our local tractor dealership and asked the boss (a PRO) what i did wrong: i had a hydraulic screw fitting that did fit together, but still leaked oil...
He took a look and said: "ah, just what i thought, your confusing XX metric size with YY BSP..." Since then i allways let this expert have a look

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.

 

[Wayne County Hose]

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

 

[Iplayfarmer]

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.
