Active Aqua Elbow Connector - Pack of 10

Match the elbow size to the inside diameter of your tubing. The 1/2" elbow is for 1/2" ID tubing — commonly used for smaller feed lines and distribution lines. The 3/4" elbow suits 3/4" ID tubing, which is standard for main supply runs, 3/4 inch fill and drain fittings, and larger reservoir-to-table configurations. If your system uses both tubing sizes, you'll need a pack of each.

Bending flexible vinyl tubing at sharp angles causes kinking — the tube wall collapses inward, restricting or completely blocking flow at the bend point. A rigid elbow connector maintains the full interior diameter through the turn, keeping flow consistent regardless of the angle. It also eliminates the tension that a bent tube places on fittings and connection points, reducing the risk of pull-apart failures over time.

For standard hydroponic pump pressures, the barbed connection holds securely without clamps when tubing is pushed fully onto both barbed ends. In higher-pressure setups or where the tubing is under tension from routing, adding hose clamps over each tubing end provides additional pull-out resistance and ensures the connection stays seated under load.

Yes — the 1/2" elbow connector is compatible with Active Aqua Black Vinyl Tubing (1/2" ID), and the 3/4" elbow is compatible with the 3/4" ID version. They also work with any third-party flexible tubing matching the specified inside diameter, making them a versatile fitting for mixed-brand system builds.

Elbow connectors are most useful anywhere tubing needs to change direction cleanly — routing around the corner of an Active Aqua 2.0 Black Reservoir, directing a supply line down to a flood table, or turning a feed line parallel to a wall. They're also frequently used at pump outlets, such as on the Active Aqua Grow Flow Bottom-Draw Pump, where the tubing needs to redirect immediately after exiting the pump housing.
