6mm Rubber Micro Irrigation Tube, 3mm ID – Flexible Black Drip Feeder Hose for Pots, Garden Beds & Greenhouses

6mm Rubber Micro Irrigation Tube with 3mm Inner Diameter

This 6mm rubber micro irrigation tube is a flexible black feeder hose with a 3mm inner diameter, used to carry water from a main drip line to individual drippers, sprayers and stakes. It is made for low-pressure micro irrigation, so you can run water right to the base of pots, planters, garden bed plants and greenhouse benches, exactly where it is needed.

The Link Between Your Main Line and Every Plant

In a drip system, the main poly line carries the water, but it rarely runs right past every plant. Micro tube fills that gap. A short length pushed onto a barbed connector in the main line can snake up into a hanging basket, across to a pot on the patio or along a row of seedlings, with a dripper or stake on the end. This lets one main line water plants spread across a courtyard, balcony or garden bed without extra plumbing.

Flexible Rubber That Bends Around Corners

Rubber tubing stays soft and bendable, so it curves around pots, corners and planter edges without kinking as easily as stiffer tube. The thick wall, with a 6mm outside and 3mm inside diameter, helps it hold its shape and grip barbed fittings firmly. The black colour also blocks light, which helps reduce algae growth inside the tube.

Where It Works Best

This tube suits pots and planters, raised and in-ground garden beds, greenhouse and shade house benches, drip irrigation kits and small hydroponic setups. It is designed for low-pressure water flow, so it works best in systems running through a pressure reducer, as is standard for most home drip irrigation.

Setting Up Micro Tube Runs

Plan where each dripper needs to go, then cut each length of tube with a sharp knife or cutters so the ends are square and clean. Use a hole punch to make a hole in your main poly line, press in a barbed connector, and push the tube firmly onto the barb. If the tube is stiff to fit, dip the end in warm water for a few seconds to soften it. Fit a dripper, sprayer or stake to the other end, and hold the tube in place with stakes so it does not pull off in hot weather. Keep runs short where you can, as long lengths of small tube reduce flow at the dripper. Always use a filter and pressure reducer at the start of your system, and flush the lines now and then to clear any debris.

Frequently Asked Questions

How do you connect 6mm micro tube to a main drip irrigation line?
Punch a hole in the main poly line with a hole punch, push in a barbed connector sized for 3mm ID tube, then press the micro tube firmly onto the barb. Softening the tube end in warm water makes fitting easier.

What fittings are required for 3mm inner diameter micro hose?
Use fittings with barbs made for 3mm ID tube, such as barbed connectors (take-offs), joiners, tees, elbows, end plugs and dripper stakes. Fittings made for standard 4mm micro tube may be too large, so check the barb size before buying.

Is rubber micro tube better than PVC for flexible drip systems?
Rubber tube stays soft and bends more easily around pots and corners, and tends to kink less. PVC tube is often stiffer, especially in cool weather. For runs that need to curve a lot or move with pots, flexible rubber is usually easier to work with.

Can I use it for hydroponics?
Yes. It suits small low-pressure hydroponic setups for carrying water or nutrient solution to plants, as long as your fittings match the 3mm inner diameter.

How long can each micro tube run be?
Keep runs as short as practical, ideally a metre or two to each dripper. Longer runs of small tube reduce the flow reaching the plant, especially at the end of a busy line.
