Loc-Line Aquarium Plumbing & Modular Hose

1/4", 1/2" & 3/4" Systems

Loc-Line is a snap-together modular hose that bends and holds its shape, so you can build return lines, spray bars, closed-loop outlets and directional nozzles in exactly the shape your tank needs.

No cutting, no gluing and no fixed angles. Snap on more segments to add length, swap nozzles to change the flow pattern, and readjust anytime your aquascape changes.Choose your size below.

Which Loc-Line Size Do I Need?

3/4"
High Flow

The 3/4" system is best for larger aquariums, sump returns and closed loops that move a lot of water.

1/2"
All-Purpose

The 1/2" system is the most versatile size for small to mid-size aquariums, canister filter returns and all-in-one tanks.

1/4"
Precision

The 1/4" system is for nano aquariums, frag systems, reactors and other low-flow lines that need a fine, targeted stream.

↓ Mixing sizes? A 3/4" to 1/2" adapter or 1/2" to 1/4" adapter lets you step down to a smaller nozzle on the same line.
★ Pro tip: Every system starts with an NPT adapter or connector that threads into your pump, bulkhead or fitting. Pick that first, then add hose and a nozzle.
