Trident 5/8-Inch Blue 50-Foot Cold Water Feed Hose

The Trident 5/8-inch cold-water feed hose is suited to freshwater plumbing that calls for more inside diameter than a conventional 1/2-inch line. Its translucent blue cover marks the cold side of the system without requiring an additional color sleeve. The inner tube is FDA-grade and intended for safe drinking-water transfer.

Polyester reinforcement is built into the flexible PVC construction to withstand normal pressure and abrasion. This diameter carries a 230 psi working-pressure specification, a 1.26-inch bend radius, and an approximately 0.866-inch outside diameter. The listed temperature range is -18°F to 149°F, even though the blue cover denotes cold-water use. Those figures help with choosing a route that avoids pinching the hose behind tanks and cabinetry.

A 50-foot box provides enough hose for routing or replacing multiple water-line sections. For a straightforward installation, match the inlet and outlet fittings to the 5/8-inch inside diameter before cutting the boxed length. Keep the blue line separated and identifiable wherever the hot and cold plumbing run together. See our additional marine water and bilge hose products for other hose sizes and constructions.
