Improving Seal Integrity in High-Pressure Flare Connections

The connection between a 45-degree brass male flare and a copper female flare in a mini-split system experiences relative movement due to temperature changes, potentially compromising the seal. The system operates at 600psi, and there is no rubber gasket, relying on metal-to-metal contact. The question is whether polishing the male end to a mirror finish can improve sealing performance under these conditions.
