How tightly should a regulator be attached to the pipe fittings?

The proper way to attach a regulator to pipe fittings is to ensure a snug fit without over-tightening, which can lead to damage. A snug attachment allows for a secure connection that minimizes the risk of gas leaks while also ensuring that the casing of the regulator is not at risk of cracking or becoming damaged.

Over-tightening fittings can stress the materials and potentially create leaks or malfunction of the regulator. Therefore, finding a balance is crucial; it must be tight enough to prevent any gas from escaping, but also loose enough to let the regulator function without undue stress on its components. This careful consideration contributes to both safety and functionality in gas systems.
