Active Aqua Black Vinyl Tubing

For drip lines and emitter feeds, the 3/16" ID (HGTB316) or 1/4" OD (HGTB25) options are the most common choices — rated for 55 PSI and 45 PSI respectively and sized to fit standard drip fittings. For main supply lines running from a reservoir or pump, the 1/2" or 3/4" ID tubing provides better flow volume with less resistance.

Yes — all Active Aqua Black Vinyl Tubing variants are FDA-approved and BPA-free, making them safe for direct contact with nutrient solutions and edible crops. The material meets food-safety standards, so it's appropriate for both hydroponic growing environments and potable water irrigation applications.

The 25-foot rolls (HGTB50GF and HGTB75GF) are available in the 1/2" and 3/4" ID sizes and are well-suited for smaller or single-tent setups where you don't need a full 100-foot run. The 100-foot rolls come in a dispenser pack format across all seven sizes, making them practical for larger installations or keeping a supply on hand for future repairs and expansions.

Yes, the flexible vinyl material cuts cleanly with standard scissors, a utility knife, or a dedicated tubing cutter. For the cleanest cut — especially on larger diameters like 3/4" or 1" ID — a tubing cutter will produce a more precise, square edge that seats better in push-fit fittings.

Maximum operating pressure at 70°F varies by diameter: 55 PSI (3/16" ID), 45 PSI (1/4" OD), 30 PSI (1/2" ID), 25 PSI (3/4" ID), and 15 PSI (1" ID). As a general rule, smaller-diameter tubing handles higher pressures, while larger-diameter tubing is rated for lower-pressure, high-flow applications. Refer to the Variant Specifications table above for full details on each SKU.

Black tubing blocks light from penetrating the line, which prevents algae from forming inside — a common problem with clear or translucent alternatives. Algae growth in irrigation lines can clog emitters, harbor pathogens, and compromise system hygiene. Using black vinyl tubing is a simple, low-cost way to maintain cleaner lines with less maintenance over time.

This tubing works with standard barbed, push-fit, and compression fittings sized to match the inside or outside diameter of each variant. The 1/4" OD tubing (HGTB25) accepts fittings sized for 1/4" OD connections, while the 1/2" ID and 3/4" ID tubing accept components like the 1/2" fill/drain fitting or 3/4" fill/drain fitting sized to their respective inside diameters. Always match the fitting type to the specific diameter listed in the variant specifications table above.
