Specifications of tube fittings below sinks

[Josh_M]

Hello, web searches are failing me, I must be looking for the wrong terms as usually fittings dimensions are easily accessible.

I am trying to figure out where to find the specifications for 1.5inch tube fittings (like seen in P-traps). Specifically the wall thickness requirements and thread specifications.

MPT threads are easy to find and ASTM codes specifies what I needed for DWV piping but I don't even know what to call these cheap tube fittings under the sink in order to look them up.

You can try that thin wall plastic stuff(assuming that's what it is) at this site.

Then look under the RESOURCE tab for specs and drawings.
Then you should find your way to drawings with dimensions. Don't think you'll find thread specs. ???

So that's what tube fittings are. I really didn't know. I just assumed they were those flimsy looking drain fittings.?????
Didn't notice any actual dimensions in that publication.
