Air shock shrader valve cross reference

Glad I clicked in here. I learned about ORB fittings....

Nope.
It's an ORB. The seat is machined for an O-ring, where a straight would not.

Connection Types: American Connections

There are many connection types all across the world. This post will help you identify and define common American connections.

Right, but the premise/context of the OP question was inferring other industry terms/names. ORB is the automotive industry.
In the manufacturing industry I work in. NPSM (mechanical) has no oring and is used in "Tank Valves". And a NPS fitting "with oring", looks to be equivalent to the ORB fitting yall are talking about.

Again, was simply lending my 2 cents from the specific industry I am in alternative to the automotive nomenclature.

EDIT: The chamfer is why i asked if there was a pic of the ends in a earlier post on here.

EDIT2: Its not really referred to as "ORB" anywhere else in the world besides automotive. To my humble knowledge. Been in manufacturing equipment for only about 10 years, so my experiences are very niche

What's interesting is....they can both seal with an o ring, washer, or a combination of the two and are both straight threads. Generally, you'd see NPS on something like electrical conduit and ORB on hydraulic stuff. I think the very in depth and technical difference is the actual threads themselves and the specs they're machined to.

Most of the ORB hyd fittings I've used had a convex washer above the o ring to help protect it or keep it from squishing out. NPS isn't usually used (from what I can see) in pressurized liquid applications. Maybe it is...not sure. All of the fittings I used on the equipment I've had were JIC, ORB, or ORFS. Sometimes an NPT, but not generally.

However, as far as I can tell, they're pretty much interchangeable between the same thread sizes, obviously.

Random ADHD hyperfocused nerd moment over :D

For the record they aren't the same, sae orb and npsm are different, that picture/article has it wrong too...while bspp fittings use an oring and backing washer like that nps doesn't it seals on the taper at the bottom like a regular flare fitting does.

Orb is a totally different but sometimes similar and much better sealing method.
I spent years and years building and working on hydraulic machines from every country just about and have seen every dumbass thread form there is.
Then you have the Japanese where each mfr makes up their own.
I wish we could all get together and decide on one in particular and get rid of npt while we at it.

Correct. NPS*M* is mechanical chamfer seat only. I cant comment on the hypertechnical from a T.O. perspective. In my ordering experience, vendors use the term NPS very loosely - such as NPSM which is the seat only, and NPS w/ Oring for no chamfer but with oring. Lol - etc.

Is japan hydraulics worse than chinese hydraulics?
 
Anybody got the specs for a 0.25 G thread?
