Difference between ORB and SAE

[wdchyd]

You guys probably don't need my input but the way I read this is the OP'r needs to change his valve and can't get the swivel adapters off (6fpx-6mb) to identify to replace it

On stuck ones, best to slice off the swivel nut then use a box-end wrench or socket to grab the remaining hex.....

More than likely it's a #6 male boss (SAE/ORB) on the control valve but best to remove and measure....

Adapter fittings are cheap, maybe best to just buy a valve you want and put on new adapters.....:thumbsup:

You are right OP wants to know what ports are in his valve, per post #3. So he needs to get the adapters off and see what he has. The swivel with an O-ring in it and NPT hose threads got me off track thanks for pointing this out.

See pics. (Ain't this new-fangled tech neat?)

The right side pic shows the entire valve.

The left pic shows a hose end and the swivel adapter thats screwed into the valve base casting.

The middle pic shows the threads on the end of the hose and the O-ring at the bottom of the swivel adapter. I am not able to remove the adapter from the casting, need a new thinner wrench to remove it.

I am trying to determine the ports I have on the casting so I know what kind of replacement control valve to buy.

"SAE" really refers to the organization that controls hundreds of different SAE specifications, but in hydraulics, it's most often used to refer to ports and fittings using SAE Straight Thread O-Ring (aka O-Ring Boss or "ORB"). In that regard, the "difference" between SAE and ORB is absolutely none. They are two different names for the same connection.

There is no way to identify the ports on the casting without first removing the swivel adapters. it could very well be and SAE/ORB port, but if your equipment is foreign-made, it could also be metric or BSP (British Standard Pipe). Once you remove the swivel adapter, you can identify and measure the threads to be sure.

The tables here will help you identify all of the popular hydraulic ports and connections.
