I'm creating this thread with a good title for searching because many TBNers have asked about what a restrictor orifice looks like and how it works. I was at my New Holland dealer yesterday and picked up a spare orifice fitting. This one is about 0.030" and is what I use in my TnT setup and my grapple. It gives me the amount of control I need to accurately position my hydraulic cylinders. The other reasons I like it are that it is inexpensive ($4.95), does not take up much room, and has normal NPT threads. The swivel fitting makes it easy to install also.

Is the orifice size stamped on the side?

:confused:

JJ, I was surprised to see that it was not. Previous one's I have bought had ".031" stamped on the hex flat, but on this one, it was only on the bin/box on the shelf. Somebody probably decided they could save money (read "make more money") by not stamping the size on the orifice. Actually, if I didn't see the box, I'd be saying this is more like .040" or .050". The hole looks big to me.

Someone might have bored it out some. You can make restrict-ors by just boring out a flat washer, maybe brass or SS. I like the needle valves, so I can set the speed, and change it whenever I like.

Are these made for 1/4 NPT and where can I find them? Believe me I have looked.

I have a link at home from company that has them, But I think you will be better served with the adjustable kind.
