compression fittings can be dot approved, that’s all there was before the quick connects came about 5 years ago. All the air hoses on heavy trucks where used with compression fittings except for the front brake chamber and compressor to drier hose. You just have to have the CORRECT DOT compression fitting with the inner hose sleave so the compression fitting doesn’t collapse the hose. Parker makes some nice fittings. The compression fittings from a hardwhare store are ment for copper tubbing and will not work correctly on the plastic dot hose.

The push-in (quick connect) have a lot of problems and we remove them after they start to leak and go with the compression fittings. They were only made to make assembly easier for truck manufacturers IMO.
