Airline Straight Connector Pack of 10

The Airline Straight Connector Pack of 10 provides inline joining connectors that allow two separate lengths of standard 4mm airline tubing to be joined end-to-end without any change in direction. These are an essential repair and extension accessory for any fishkeeper, enabling a cut or broken airline to be quickly rejoined or a short airline to be extended without replacing the entire run.

Each straight connector has two barbed arms in line with each other; pressing airline tubing firmly onto both barbs creates a secure, airtight junction that maintains full airflow without restriction. The small profile means the connector sits discreetly in the tubing run and does not add meaningful weight or bulk.

Supplied in a pack of 10, these connectors serve double duty as both repair spares and planned extension components when building out a system. They are also used to join silicone and PVC tubing sections in hybrid systems. Compatible with all standard 4mm airline tubing.
