3/4″ White Poly Mainline Tubing (820×940) – UV-Stabilized

Description

The line that feeds your feed lines.

This 3/4″ (820×940) white poly is a mainline — the higher-capacity tubing that moves water and nutrient from your pump or manifold out to the 17mm laterals that hold the emitters. Bigger bore means less friction loss over distance, so every zone sees the pressure it’s supposed to.

White and UV-stabilized for the same reasons that matter on the laterals: cooler operating temp in bright rooms, light blocked at the wall to keep algae out, and a resin that won’t get brittle on you.

Use it as the trunk line in a container drip layout, sized to carry the combined flow of the laterals downstream. 500 ft for a room, 1000 ft for a full facility run.

We design mainline-to-lateral layouts for cultivation facilities — if you want the pipe sizing done right the first time, reach out.
