great tip for distinguishing between the tapered and parallel threads.

Great video.
Most consumer automotive fittings are described as AN. Could you comment on the consistency and interchangeability of these, as well as their relationship to JIC?
I'm only just now looking at such systems and am wondering how big a mess I could get into. Thanks
They are effectively the same. AN is an army standard as opposed to an SAE standard. They are 100% interchangeable.
Hello and thanks for the great instruction on a difficult topic from my point of view as non-professional in hydraulics. Looking on my Clark C500 forklift and Kubota L2850 compact tractor, I am now looking forward more optimistic to getting the jobs done.
My Clark has an (Eaton)Vickers valve on the right hand side, which is typically installed for side-shifter, but is out if order since I bought the forklift. The lever is missing, only the operation bar comes out on the top of the valve. Further more, there are two fittings installed, which I now - after your lesson - would call JIC fittings ( guess 3/8 or 1/2" from memory, but I will check diameter and thread pattern again). There is one point, which I don't know: The open top of the JIC connectors seem to be plugged by a bowl or something like that. Will this "sealing" device be retracted, when I move the operating pin up- or downwards or do I have to unscrew the connecters, put off the plugs and screw them in again, before connecting the hose etc? 2. Concerning my Kubota tractor, I found the threads in the manifold bloc are 3/8" NPT resp 1/2"NPT. As there is no valve for any devices installed - apart from the totally integrated 3-point at the rear end, I have the chance to build up a trouble free hydraulic system, lasting for eternity. In Germany, I very often come across with metric fittings (M18*1.5 or M22*1.5). Hose or tube connectors came with a conus, like the JIC or flat with an o-ring for blocs etc. What I learned so far about sealing a hydraulic system is, that I will not go for NPT or other tapered threads, which need teflon tape or similar sealer ( silicon, hylomar). What can I expect from the different threads/ connectors ( JIC, BSP, BSP-P, Metric, etc, etc.) in terms of sturdiness, longevity, durability? I would like to keep the system simple ( one thread/type for all where ever possible) and trouble free. Is JIC the best? Thanks in advance Heinz
Go with BSPP with O-ring for block ports and JIC male/female connections 👌
Wow this is high frustrating when you got a stripped thread and none of your tap and die set fits. I have a high pressure fuel rail that needs to be repaired. Only like 2 threads are damaged. I found that a 3/8 flare fitting fits the line. But I still don't know the thread pitch to try and find a tool to help clean the threads. Is there any other kind of thread it could be besides sae or metric?
Cut-in face doesn’t use any seals!!! It literally cuts in to the body! Other types of BSPP port fittings are integrated seal, captive seal or bonded seal.
ótimo. moro no Brasil e eu tenho uma prensa mb350 manulli.
