What component in irrigation systems helps avoid corrosion at connections?

Gel-filled connectors are designed to prevent corrosion at connections in irrigation systems by providing a protective barrier against moisture and environmental factors. These connectors are filled with a protective gel that acts as a sealant, preventing water from penetrating the connection points where metal components might otherwise come into contact with moisture. This is especially important because moisture can lead to rust and degradation of metal parts, which can compromise the integrity and longevity of the irrigation system.

In contrast, plastic tubing is generally resistant to corrosion, but does not specifically address connections between different materials. Metal clamps can effectively hold components together but may create contact points that are prone to corrosion without additional protective measures. Rubber grommets can help shield wires or tubing from sharp edges but do not necessarily provide the same level of protection against corrosion at connections as gel-filled connectors offer. Thus, gel-filled connectors are crucial for extending the lifespan of the system by maintaining the integrity of connections.
