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

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.
