First one is a 2 mm wall at $75 a chunk. Second one is 1.5 mm at $33 a chunk. It’s not
obvious why one is “compression fitting” and the other is “weld” rated. In any case, I suspect
you need the 2X more expensive, done just for compression fitting versionl. If anybody
is looking in their junk box, time to take your calipers out and check if that wall thickness 
is 2.0 mm or 1.5 mm (I guess …).
