Netafim UV Polyethylene Tubing – 3/4 in 100 ft

The Netafim UV Polyethylene Tubing is a 100 ft roll of 3/4 in Super Flex tubing designed for outdoor drip and irrigation systems. Its UV-resistant, fully opaque gray construction blocks light to prevent algae growth and holds up against direct sun, heat, and harsh chemical exposure while maintaining cooler water temperatures in the line.

Netafim UV Polyethylene Tubing Specifications

Key physical specifications for the Netafim Super Flex UV polyethylene tubing, 3/4 in size, 100 ft roll.

Why Choose Netafim UV Polyethylene Tubing

Netafim’s Super Flex UV tubing addresses several practical challenges that come with running irrigation lines in exposed outdoor environments. Here is what distinguishes this tubing from standard clear or black PE options:

• UV-stabilized formulation: The tubing is engineered to withstand prolonged direct sun exposure without cracking, becoming brittle, or losing flexibility. Standard polyethylene tubing degrades quickly under UV, requiring replacement far sooner than this product.
• Completely opaque construction: Light penetration into irrigation lines encourages algae growth, which can clog emitters and drip heads. The fully opaque gray tubing blocks light transmission, keeping the water pathway clean.
• Cooler water delivery: The gray color and UV-resistant formulation reflect heat rather than absorbing it, which helps maintain lower water temperatures in the supply line — a meaningful benefit for root-zone-sensitive crops and hydroponic systems where elevated water temperature stresses plants.
• Chemical resistance: The polyethylene material holds up against the fertilizers, pH adjusters, and cleaning agents commonly used in hydroponic and intensive crop production settings.
• 100 ft continuous roll: A single roll covers a substantial run without fittings or joins, reducing potential leak points and simplifying installation across larger growing areas.

Best Uses for Netafim UV Polyethylene Tubing

This tubing is sized at 3/4 in nominal diameter, which positions it as a main supply or header line rather than a final-run drip emitter line. Typical applications include:

• Drip irrigation header lines: Run 3/4 in tubing as the primary supply line from pump or reservoir to distribution manifolds, then branch off to smaller 1/4 in or 5 mm emitter lines. The 3/4 in bore supports adequate flow volume for larger grow areas.
• Outdoor hydroponic system plumbing: Greenhouses and outdoor NFT, DWC, or drip systems with exposed runs benefit from the UV-resistance and opaque construction, which standard supply tubing does not provide.
• Commercial and hobby greenhouse installations: Where tubing will be routed along the exterior or under translucent covers that do not fully block UV, this tubing maintains integrity over multiple seasons.
• Replacement supply runs: Growers upgrading aging clear tubing that has yellowed, cracked, or accumulated algae can use this as a direct replacement at the 3/4 in header size.
• Container and raised-bed irrigation: Connect a pump output directly to this tubing to distribute nutrient solution or water across rows of containers before stepping down to smaller emitter lines. If your system uses an inline filter on the supply line, this tubing fits into that plumbing arrangement at the 3/4 in header stage.

Compatibility

The 3/4 in nominal size with 0.82 in ID and 0.94 in OD is compatible with standard barbed, compression, and threaded fittings designed for 3/4 in polyethylene tubing. This is a widely used size in the Netafim product ecosystem and in general irrigation supply, so fittings are broadly available.

This tubing works alongside the broader Netafim Super Flex UV line, which also comes in 5 mm, 17 mm, and 1 in sizes. If you need a main supply run at 1 in and step down to 3/4 in for distribution zones, both sizes use the same material and UV-resistance properties, making mixed-size installations straightforward.

Because the tubing is polyethylene (not PVC), it is flexible enough to route around corners without rigid elbows in most installations, though it does not have the extreme flexibility of silicone tubing. It is not rated for high-pressure applications; use at standard low-pressure drip irrigation operating pressures. For systems that require monitoring of dissolved solids in the supply water, pairing this tubing with an EC measurement tool at the reservoir or inline helps ensure nutrient concentration remains on target as water travels through the supply run.
