Help identifying hydraulic fittings. JIC and ORB

[chad22]

On the fitting in this ebay listing. (20) 6400-08-08 Steel Hydraulic Fittings 1/2" JIC x ORB - eBay (item 380171052459 end time Dec-17-10 14:07:42 PST) Which is the JIC end and which is the ORB end? I'm assuming the ORB end is the one with the Oring? But not sure.

Thanks

Chad

You are correct!

ORB means O-Ring Boss JIC fittings have a 37* taper/flare on them.

Thanks. I just realized I got the 1/2" hoses with NPT ends instead of the JIC ends. So I was looking around on tractorsupply's website and found this adapter. It's says it's a ORB to Female pipe adapter. But doesn't say NPT.

So is this the one I need for my NPT hoses? Swivel Adapter, 1/2 in. Male O-Ring Boss x 1/2 in. Female Pipe Swivel - 1818626 | Tractor Supply Company

Thanks

NPT = national pipe thread.

It would help a lot if you told us what you are trying to connect?

I'm trying to connect some 1/2" hydraulic hoses with NPT Threads to my control valve . BLB - BM20/5 - 5-Spool Control Valve - eBay (item 320295452598 end time Dec-23-10 12:31:17 PST) That has 1/2" ORB threads. So I was wondering if that fitting would fit a NPT threaded hose?

So I need a 1/2" male orb fitting with a 1/2" female NPT end. So that way I can connect my NPT hoses to my valve with ORB threads. I searched for ORB to NPT fittings on tractorsupply.com and all I could come up with was this fitting Swivel Adapter, 1/2 in. Male O-Ring Boss x 1/2 in. Female Pipe Swivel - 1818626 | Tractor Supply Company

I was wondering if pipe meant NPT even though they don't mention NPT.

I hope I explained that right. If not let me know.

Chad, "pipe" does indeed mean NPT. The fitting you linked from TSC is correct. You should also consider DHH, they have a much wider selection than does TSC.

Here is a thread chart I use all the time, it may be helpful to you: http://www.discounthydraulichose.com/Size_Charts_s/55.htm

What you'll probably end up doing is either getting new ends swaged onto your hoses, or use a female pipe coupling between the hose and a 1/2 NPT male to 1/2 male ORB adapter. If the hoses aren't too long, it may be worth your while to get new ones made, otherwise you're going to have an awkward looking conglomeration of fittings.

The ORB fittings aren't tapered threads, so the NPT fitting will probably leak if you mount it directly to the valve.

Another option is to get an "adjustable" 90* elbow with female pipe threads on one end, and male ORB on the other. The ORB end has a bulkhead fitting type nut and washer behind the o-ring so you can set the angle where you want it, then screw your hose end into the female pipe end. I used these except with a JIC end in place of the pipe thread.

KennyD,

Slightly off topic, I know JIC is 37*, is JIS 45*??

No personal experience with those, but according to Parker it's 30*.

Thanks everyone. I have another question. What does "JIC" actually stand for?

I can't seem to find out what it means? And I'm new to all this hydraulic stuff. :laughing:

JIS is a whole nother animal. It's a real oddball. If memory serves me correctly, Allis-Chalmers made in Romania use them as do some others. DHH has a nice ID chart on their website. Easy way to tell ORB is to see if it screws into a female JIC. They are the same thread.

If this helps understand the fitting you are asking about, the hoses are all NPT ends into swivel fittings.

JIC (Joint Industry Council)

JIS

Japanese Industrial Standard: This coupling looks similar to our MJ and FJX fittings. There are two major differences - the threads are BSP and the seat angle is only 30-degrees instead of 37-degrees.

:mur::mur: Why oh why can we not have a single world standard... I'm a millwright and I find it confusing, God help us all.

Gary, in your picture, the male pipe thread seals in the upper part of the fitting, but what seals the swivel portion? I assume it's an "adjustment while installing" kind of swivel, not meant to pivot during operation?

"single world standard" ...common currency....UN...Seems no mater what, the world can't get on the same page. Everyone has their "nationalistic" fittings. The UK, and all associated (most of Asia) adopted British threads, BTP, BSPP, JIS. The US, and North America started with NPT, then , SAE, JIC, ORB, all based on pipe or sae thread sizes. Europe went metric, with France using flare, Germany using DIN.

Think of the fun of working in the US, trying to install an Irish built attachment on a German built machine :^p it's enough to make one go screaming into the woods

These type of swivel fittings allow you to set the hose to the direction you need and then tighten down. Once they are tightened, they don't move. They are not a "live" swivel that will move during operation.
