Self-sealing connectors or hand valves are used because they

Explanation:
Self-sealing connectors and hand valves are designed to keep the refrigerant contained whenever hoses and gauges are connected or removed. The moment you detach or attach lines, unsealed connections can allow some refrigerant to escape to the atmosphere. These devices seal off automatically, so only a minimal amount leaks out during the connection process. This minimizes refrigerant loss, helps protect the environment, and supports proper regulatory and cost considerations. They aren’t primarily about increasing pressure or flow, nor are they specifically for preventing contamination of the refrigerant.
