4mm Micro Irrigation Barbed Fittings & Valves

These 4mm micro irrigation fittings make it easy to build, extend or repair drip and micro watering systems around the garden or greenhouse. Select the fitting type you need and create tidy pipe runs that help deliver water where it’s required, reducing waste and saving time on hand watering.

Designed for use with 4mm inside diameter micro supply tube, the range includes common connector shapes plus flow control options. The fittings are barbed for a secure push-fit connection, and the valve option allows simple on/off control to adjust watering to different plants or zones.

Use elbows to route tubing neatly around corners and planter edges, tees and crosses to branch into multiple lines, and straight joiners for extending runs or making quick repairs. Goof plugs are ideal for sealing an unwanted punched hole in the main line, while a hypodermic-style connector can be used to connect micro tubing into a larger supply pipe after making a suitable hole.

These components are suitable for garden beds, borders, patio containers, hanging baskets and greenhouse or polytunnel installations. Choose the correct “Item” variation for your setup, then pick the pack quantity you require for small fixes or larger projects.
