Poly Tubing, Nat 5/8" OD x 1/2" ID, 50'

This Hudson Extrusions natural poly tubing arrives as a convenient 50-foot coil in a 5/8" OD x 1/2" ID size, giving installers plenty of length for larger brine and drain runs in a single, easy-to-store package. The bigger 1/2" inside diameter supports noticeably higher flow than smaller tubing, making it well suited to softeners and filtration equipment that move more water per regeneration or backwash cycle. Buying it as a coil means you have enough on hand to finish the job without splicing mid-run, which keeps installations clean and reduces the number of potential leak points along the line.

Made from flexible polyethylene, the tubing resists corrosion and stands up to the brine, chlorinated water, and dissolved minerals that are part of everyday water-treatment service. The natural translucent wall is a quiet but valuable feature: it lets you confirm flow, spot trapped air pockets, and verify draw during commissioning, which saves time chasing problems later when something is not behaving as expected. The coil format keeps the tubing tidy and protected until you are ready to pull and cut exactly the length you need, and the larger diameter retains good flexibility so it still routes neatly around tanks and valves.

Where it fits

• Brine and drain lines on larger residential or light-commercial softeners
• Higher-flow connections within treatment skids and manifolds
• Feed lines for metering, dosing, and chemical-injection equipment
• Replacement coil for worn, kinked, or undersized existing runs
• Applications needing 1/2" ID flow in a manageable 50-foot length
• Convenient bulk length for installers who service multiple systems

The 50-foot coil weighs roughly 2.2 lbs and pairs with standard fittings sized for 5/8" OD tubing, including push-connect, compression, and barbed styles. For dependable, leak-free joints, cut the tubing squarely, deburr the edge, and seat it fully into each fitting before pressurizing. Support long runs to prevent sagging, and keep bends gentle near connections to avoid stress over time that could lead to fatigue or failure. It is a practical, economical length that gives installers room to work and the confidence that they will not run short partway through an installation, making it a smart choice for any shop that handles larger softeners and filtration systems on a regular basis.
