DIYers, plumbers, and HVAC technicians who work with 1\/2\" pipe systems need a 3-way ball valve that handles the job cleanly the first time.\u003c\/p\u003e\n\u003cp\u003eThis 1\/2\" brass 3-way ball valve is available in four port configurations: all three ports as M1\/2\" male threaded ends, mixed M1\/2\" threaded and hose barb combinations, or all three as hose barb ends — so you can match your existing lines without adapters. The valve body is machined from solid brass for durability and corrosion resistance. Available in packs of 1, 2, or 3 to cover single repairs or multi-point installations.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include splitting a 1\/2\" natural gas or propane supply line between two appliances, diverting compressed air in workshop pneumatic systems, and managing water distribution in irrigation or plumbing manifolds — all scenarios where a compact inline 3-way shut-off valve for 1\/2\" pipe saves time and eliminates extra tee fittings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- ② COMPATIBILITY BAR --\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for standard 1\/2\" pipe systems.
