Am I retarted or do they just not make this ****.

A hydraulic hose end is a female fitting. I can NOT find a metric to NPT fitting or a metric to metric union fitting.

 

Why tap it out metric? I know there can be drawbacks to pipe tapping the iron due to the fact if you over tighten the fitting you can crack the iron. I guess my point is that there is many NPT and straight pipe thread to hydraulic fittings available. Pipe threads don't need to be tightened that much to seal. Most people over tighten them. The crush washer is only necessary for straight threads that shoulder on a flange. Hydraulic uses a compression end.

I not sure is this will help but you need the adapter thats threaded into the iron to have a male end left sticking out to connect the female on the hose. It is a straight thread with a pitch comparable to pipe thread pitches. There will also be a cone at the end of the fitting that will fit in the flare of the tube in the female fitting. The nut only compresses the two together. Do not over tighten this fitting either. The seal is easy to make. The combination of thread and tube size has been standardized and is referred to by a number. The AN- number.

If I way over simplified or did not help I apologize and did not mean to insult your intelligence.

 

yeah its female, my 90 is a male male fitting.

 

Yea I knew it had to be a male male, but I honestly can't find anything like that after an hour or more of looking. I'll have to go and talk to the guys at the shop I was going to get the lines made up at, and see if they know what I should do. I'm not opposed to running ss lines but it would be much more simple to do it this way with less leaking points.

 

OK. Back-up a bit. Concerning the male to male fitting in the iron, I was referring in my last post first paragraph to the end that threads into the iron. Metric taper pipe is a Whitworth thread and is hard to find here. That is why I suggested NPT or a straight thread with compression washer. I can see you having problems finding AN to metric pipe. Unless it's common from Earl's and the like.

 

I was referring to metric straight thread with an aluminum compression washer. Even simply tapping the front iron with a brand new NPT tap to fit a 12-AN adapter has given me cracking. Straight threads have never given me any issue. Typically, I use an Earl's adapter.

I use 10-AN over something smaller simply due to the restrictive nature of 90 degree fittings.

 

Exactly^^^ They make plenty of AN to everything else adapters. But nothing Metric to NPT so that I can thread the metric end into the iron and screw the hydraulic hose onto the NPT fitting.

 

I'm not seeing what you have going on. Does your hydrolic line have NPT ends? Female? Usually they have like a flare nut. Does the NPT end swivel or rotate? If it is fixed then you will need more then one fitting for assembly.
