GROCO 1/2" 4-Way Tank Selector Kit

The GROCO 1/2" 4-Way Tank Selector Kit (model TS-350-T) is a marine-grade fluid distribution system designed for vessels requiring selective access to multiple independent tanks. This kit integrates a single full-flow valve mounted on a stainless steel bracket, enabling operators to isolate and draw from different tank sources—such as fuel, freshwater, or waste systems—without disconnecting hoses or breaking lines.

The TS-350-T features two 1/2" straight hose barbs and one 3/8" 90-degree hose barb, providing flexible plumbing configurations for different tank layouts and installation geometries. The handle rotates in 90-degree increments, allowing precise alignment with your vessel's existing piping without requiring additional adapters or bends. Two label options—port/starboard or fore/aft orientation—accommodate both conventional and custom tank arrangements. All wetted surfaces are stainless steel, essential for saltwater environments where corrosion resistance directly affects system longevity and reliability.

This selector kit suits cruising sailboats, power vessels, and work boats where crew must switch between multiple independent water, fuel, or waste tanks without leaving the helm. It eliminates the need for multiple manual valves or complex manifold arrangements, reducing installation footprint and maintenance points. The straightforward single-valve design provides reliable, quick tank selection during operation or emergency scenarios.

GROCO tank selectors are standard equipment on bluewater and commercial vessels where system durability and corrosion resistance are non-negotiable. The TS-350-T represents proven design with a focus on eliminating leaks and failure points common to older multi-valve approaches.
