Fluid Fittings 37 Degree 1

[drawoh]

I am trying to identify some fluid fittings off of some CAD models, and I am trying to make sense of the terminology.

Are 37[°], AN flare, JIS and SAE[ ]J514 all the same thing? If so, what is the preferred terminology?

Locate an Aeroquip, Parker, or other fluid fittings catalog. The catalogs usually have a pictorial explanation of the different fittings that you have identified in your post.

Hi JHG

Within the fluid power industry such a fitting is known as a JIC fitting (say the letters "Jay-Eye-See" or pronounce it as a word to rhyme with "quick"). You can also call it a "37 degree flare", and some fittings manufacturers refer to it as "AN flare". I think AN stands for "American National".

JIC stands for Joint Industry Council (sometimes Committee, sometimes Conference - it doesn't matter because the group is defunct anyway). The standard SAE J514 covers this arrangement and has been mirrored as ISO 8434-2 but, IMHO, these numbers aren't spoken aloud as often as "JIC".

By the way - this is NOT a "JIS" fitting. In this context JIS stands for "Japanese Industrial Standard". Some JIS fittings are similar to JIC fittings but they have a 30 degree external flare and use metric or BSP threads.

I hope not to offend anyone, but I once heard that "J.I.C" actually stands for "Jesus, I'm Confused!". Maybe that should be raised to the status of the Pipefitter's Prayer?

Oldhydroman,

That Japanese standard threw me off too.

So all of these are the same thing?

After reading this I'm still confused. Let me know if it answers your question.

Compositepro,

I think it helps. I have added the link to my project notes.

Thank you.

The preferred teminology is whatever causes your buyer to read the print/BOM line item and order the part you actually want.
