Raindrip 1/2-Inch Drip Irrigation Supply Tubing 200 ft — Black Polyethylene, UV-Resistant Mainline

Raindrip 1/2-inch poly supply tubing is a durable 200-foot coil designed to carry water as a main or feeder line for drip irrigation systems.

This 1/2-inch Raindrip tubing is engineered for flexible, long-lasting performance in garden and landscape drip systems. Constructed with multi-layer polyethylene — virgin inner and outer layers with a reinforced core — it resists UV exposure and everyday wear while keeping water flowing to emitters, drippers, and connectors. The tubing’s dimensions (0.620" OD, 0.520" ID) make it compatible with common barbed fittings and standard punch-in emitters, so you can route water efficiently across beds, containers, and plantings.

How do I use this tubing as a main supply line?

Use the Raindrip 1/2-inch tubing to run water from your source (timer, valve, or faucet) across the area you want to irrigate. Its diameter and wall strength are suitable for holding shape under typical garden pressure, and it can be connected to barbed adapters, backflow preventers, or filters.

• Cut to length with a utility knife for a clean connection.
• Attach to a faucet or valve with a barbed adapter and clamp.
• Install filters and pressure regulators upstream if required.
• Anchor the line with stakes to prevent kinks and movement.

Can I punch in emitters and drippers directly into this tubing?

Yes — the 1/2-inch Raindrip tubing is designed for punch-in emitters and micro-sprayers, making it simple to add localized watering points along the line. Use a proper hole punch designed for drip systems to ensure a snug seal and avoid leaking.

• Punch holes at recommended spacing for your plant needs.
• Insert barbed emitters or micro-tubing connectors until fully seated.
• Test the system for leaks before burying or covering the line.
• Replace or reposition emitters without cutting the main line.

What planting situations is this tubing best for?

This tubing works well across a wide range of landscaping and garden uses, from long rows of vegetables to grouped shrubs and container plantings. It functions as a mainline, feeder, or dripper line, giving you flexibility to design zones with differing water needs.

• Vegetable rows and raised beds — run long, continuous lines.
• Shrub and tree watering — serve multiple emitters from one feed.
• Container gardens and hanging baskets — use as a feeder to smaller tubes.
• Groundcover and flower beds — place emitters where needed for even coverage.

How durable is the tubing for outdoor use?

Raindrip’s multi-layer construction uses 100% virgin polyethylene on both inner and outer layers to resist UV degradation and maintain flexibility. A recycled-content core adds tensile strength while keeping the tubing lightweight and easy to handle.

• UV-resistant outer layer to reduce cracking from sun exposure.
• Robust inner wall to resist water stress and maintain flow rates.
• Flexible enough for curved runs but stiff enough to avoid sagging.
• 200-foot coil reduces the need for frequent joins in larger projects.

Who this is for: Gardeners, landscape professionals, and DIY homeowners who need a reliable, easy-to-install supply or feeder line for drip irrigation will find this Raindrip 1/2-inch tubing practical. It suits anyone building or expanding a drip system for vegetables, ornamentals, trees, container plantings, or low-water landscapes who values durability, compatibility with common fittings and emitters, and the convenience of a long continuous length.
