Which method is preferred for mini-split systems and avoids flaming action?

Explanation:
For mini-split systems, flare connections are the preferred method because they create a tight, leak‑ready seal without any torch work. A flare is formed on the copper tube with a flaring tool, producing a cone that mates with the corresponding fitting; when the flare nut is tightened, it compresses the flare against the fitting to seal. This mechanical process means no flame is needed, which reduces fire risk in tight spaces and near insulation. While other methods exist, the standard mini-split fittings are designed for flared joints, making flare connections the most reliable and practical choice in field installations.
