Legend Valve 355-246E 1/2" x 66 Black Assortment Pak tubing

1/2" x 66 Black Assortment Pak

Legend Valve 355-246E tubing supplies a 66-foot coil of half-inch black hose for residential and light-commercial plumbing jobs. Installers use it for water supply, drainage or low-pressure fluid transfer where a flexible, cut-to-length run is required. The pack format keeps the coil tidy on the truck or shelf until the next service call. It is not suited for high-pressure hydraulic systems or potable-water lines that demand certified drinking-water ratings.

Sustained pressure and temperature tolerance

The hose maintains its bore and wall integrity during continuous flow at typical household supply pressures without ballooning or weeping at the fittings. Repeated thermal cycling from cold inlet water to warm discharge does not cause permanent set or cracking in the tube wall. Vibration from pump start-up is absorbed by the flexible wall rather than transmitted to rigid pipe joints. It is not rated for continuous steam service or constant elevated temperatures beyond standard domestic hot-water limits.

Heat resistance, noise and installation handling

Black pigmentation shields the polymer from UV degradation when runs pass through sunlit crawl spaces or roof penetrations. The smooth inner surface minimises turbulence noise during high-volume draw such as simultaneous fixture use. Lightweight construction allows one-person uncoiling and cutting with a utility knife, reducing strain on the installer. No special tools or solvent cements are required for standard barbed or clamp connections.
