1/2″ ID Pipe 100′ Roll (Custom AutoPot Tubing)

The Auto Pot 1/2″ ID Pipe 100′ Roll is a 100-foot length of black, non co-extruded, unmarked 1/2″ inner-diameter irrigation tubing manufactured to Auto Pot’s specifications. It is intended for growers who need to extend or replace supply lines in AutoPot gravity-fed watering systems, or for anyone building custom drip and irrigation runs in a grow room or greenhouse.

Why Choose This AutoPot Tubing

AutoPot systems rely on consistent, low-pressure gravity-fed water delivery. The tubing that carries nutrient solution to each tray or pot must maintain a stable inner diameter and resist kinking, UV degradation, and microbial growth over long run times. This roll is manufactured to AutoPot’s own specification, which means it fits AutoPot connectors and fittings without adapters or makeshift workarounds.

• Correct sizing: The 1/2″ inner diameter matches AutoPot’s standard supply-line fittings, so connections seat properly without leaks.
• Non co-extruded construction: Unlike some dual-layer tubing, this pipe has a single-layer wall, which keeps the bore consistent and simplifies cutting to length.
• Unmarked surface: No printed measurements or logos on the outer wall, which avoids confusion when laying multiple runs side by side in a busy grow room.
• Black coloring: Opaque black tubing limits light penetration into the water line, which reduces algae growth inside the pipe over extended use.
• 100-foot roll: A single roll provides enough tubing for most mid-sized to large AutoPot installations, reducing the need for mid-run joins and the leak risk that comes with them.

Best Uses for the 1/2″ ID Pipe 100′ Roll

This tubing is designed for use in passive and gravity-fed hydroponic irrigation setups. Its primary application is AutoPot system runs, but the 1/2″ inner diameter is common enough to serve other low-pressure irrigation needs in a controlled environment.

• AutoPot supply lines: Run from reservoir or header tank to individual AQUAvalve-equipped trays across a grow room floor.
• Greenhouse irrigation runs: Connect a gravity-fed water source to a series of drip emitters or watering stakes along a growing bed.
• Custom manifold builds: Use as branch lines from a central header to distribute water to multiple grow sites in a single zone.
• Replacement runs: Swap out aged, kinked, or fouled supply lines in an existing AutoPot installation without purchasing a complete new kit.
• Low-pressure drip systems: Pair with standard 1/2″ drip irrigation fittings for non-AutoPot drip setups that require food-grade, opaque tubing.

If you are filtering your incoming water before it reaches the system, a line filter placed before the header connection is a practical addition. The Dilution Solutions 1-1/2 in. filter with 200-mesh screen handles sediment on larger-diameter mains and can be plumbed upstream of your 1/2″ runs.

Compatibility

This tubing is sized for the 1/2″ (16 mm) fitting standard used throughout the AutoPot product line. It is compatible with AutoPot push-fit connectors, T-pieces, elbows, and AQUAvalve inlet fittings sold separately. Because the pipe is non co-extruded and unmarked, it also accepts standard 1/2″ barbed or compression drip-irrigation fittings from other suppliers, provided those fittings are rated for the inner diameter.

AutoPot systems operate at very low operating pressures — typically gravity head from an elevated tank rather than a pressurized mains connection. This tubing is suitable for that pressure range. It is not specified for use with high-pressure mains supply without a pressure regulator upstream.

For growers who condition their water before use, pairing this tubing with a reverse osmosis system upstream of the reservoir gives finer control over the nutrient solution your plants receive. Clean, low-TDS source water extends the service life of all irrigation components, including the tubing itself.

If your system also requires aeration in a reservoir or sump, the Active Aqua air pump is a commonly paired component for maintaining dissolved oxygen levels in gravity-fed AutoPot reservoirs.
