Trident 1/2-Inch Blue 50-Foot Cold Water Feed Hose

The blue translucent jacket on this Trident feed hose clearly marks a cold-water circuit behind the panels of a boat. It is a 1/2-inch inside-diameter line made with an FDA-grade drinking-water-safe tube, so it is intended for freshwater distribution rather than bilge discharge alone. The hose comes in a 50-foot box for routing between pumps, tanks, faucets, and other compatible water connections.

Its reinforced wall is designed to remain flexible during installation. Three-ply polyester reinforcement gives the PVC tube strength and resistance to abrasion during regular use. Trident rates the 1/2-inch size for up to 250 psi working pressure and lists an approximately 0.98-inch bend radius. The temperature range extends from -18°F to 149°F, although the blue marking identifies this as the cold-water model. Its stated outside diameter is about 0.777 inch, a helpful number when passing through clips or confined spaces.

Blue and red water lines are easier to service when each color consistently follows its intended circuit. Match the fitting size to the 1/2-inch inside diameter and route the line without rubbing against sharp edges.
