You can explore the differences here.
Similarities and differences
Similarities – Threaded and compression fittings both use threads to help make their connections. However, they use the threads differently.
Differences – Threaded fittings have a 1-piece connection end that is used to connect to port/block. These threads create the seal for the connection with the support of Teflon tape or pipe dope and are manufactured in a tapered, cone-shape. Whereas compression fittings have a 3-piece connection that is tasked with its connection to tubes. Compression ends typically are a parallel shape and instead of sealing on the threads, the seal point is created with the assistance of a ferrule (ring, olive or sleeve) and a compression nut. So in this case,... less
