3mm Dripper Line — 20m Roll

3mm Dripper Line — 20m Roll

A 20-metre bulk roll of 3mm fine-bore dripper line — the feed tube that connects main irrigation manifolds to individual drippers. Perfect for DIY hydroponic irrigation kits or for replacing worn, kinked, or blocked dripper line in existing systems. Works with 4mm manifold fittings.

Why growers choose 3mm dripper line:

• 20-metre bulk roll — enough for a large DIY irrigation build or multiple repairs
• 3mm fine-bore — standard dripper-line size for precise per-plant feeding
• Works with 4mm manifold fittings — fits into 4mm barbs with a firm grip
• Replacement or DIY-build material — either replace blocked line or build a new system from scratch
• Flexible enough to route cleanly — bends around obstacles without kinking
• UV-resistant plastic — doesn't degrade under grow-room lights

Who it's not for:

For AutoPot systems (6mm dripper line) or IWS (13mm), use the system-specific line. For very small setups (single plant, single dripper), a 1m length is cheaper than a full 20m roll. Use the 3mm green hole punch when adding drippers into 13mm supply pipe.
