Drip Irrigation Tubing

Drip Irrigation Tubing

Drip tubing does one of two jobs in a system: it either routes water from point to point with no openings along the way, or it releases water continuously through built-in emitters spaced along its length. Getting the right type for the right section of a layout is the difference between a zone that waters exactly where it should and one that either misses plants or waters bare soil between them.

Blank tubing — sometimes called distribution tubing — has no holes and is used to carry water from the valve or Control & Conversion Kits out to the planting area, and to connect individual emitters back to the main line. Because it doesn't release water itself, blank tubing can run under mulch, along a fence line, or beneath a walkway without watering anything along the way — useful for reaching a bed that's set back from the water source.

Emitter tubing (sometimes called drip line or soaker line) has outlets built directly into the tubing at fixed intervals, which makes it the faster option for rows of closely spaced plants like vegetable beds or hedges, since it removes the step of installing separate Drippers/Emitters one at a time. Pressure-compensating emitter tubing keeps output even across long runs or sloped ground, where standard tubing would otherwise deliver more water to the plants closest to the valve.

Sizing follows a simple pattern: 1/2" tubing is the standard for main distribution runs carrying water across a yard or bed, while 1/4" tubing branches off the main line to reach individual plants or containers. Both sizes connect using barbed Fittings sized to match, so a layout can mix distribution and feeder tubing without needing different connection hardware.
