1PC Brass Straight 2Way Barbed Reducer Connector Coupler (19mm → 16mm Hose OD) Overview This singlepiece brass straight barbed reducer connector joins a 19 mm hose OD to a 16 mm hose OD. The simple, robust design provides a reliable, lowprofile connection for low to moderatepressure fluid and air lines. Key benefits Creates a secure, leakresistant connection between hoses of different outer diameters without modifying existing lines. Durable brass construction resists corrosion and holds shape under normal use for longterm reliability. Barbed ends give mechanical grip to the hose for reduced slippage; use with hose clamps for added security. Straight, twoway design keeps flow smooth and minimizes pressure drop across the join. Key attributes Quantity: 1PC (one connector) Material: Brass (solid, corrosionresistant) Type: Straight 2way barbed reducer connector / coupler Size compatibility: Designed to connect hoses with 19 mm outer diameter to hoses with 16 mm outer diameter Installation: Pushfit onto hose barbs; recommended use of hose clamps for a secure seal Functionality and compatibility Fits flexible hoses made of rubber, vinyl, PVC, silicone and similar materials with 19 mm and 16 mm outer diameters. Intended for low to moderatepressure applications where a reliable mechanical connection is required. Not supplied with clamps; clamps or crimp rings are recommended to ensure leak performance. Performance and installation tips Cut hose ends squarely and slide fully onto the barbed sections until seated against the shoulder. Tighten an appropriate hose clamp over each barb to prevent movement and leaks. The straightthrough profile maintains nearfull flow between the two hose sizes while providing a stepped reduction. Typical applications Irrigation and garden systems: join a 19 mm main line to 16 mm distribution tubing for drip lines or sprinklers. Pump and transfer lines: adapt a pump outlet or reservoir connection from 19 mm to 16 mm hose for water transfer or recirculation. Hydroponics and aquariums: connect larger feed lines to smaller distribution tubing in lowpressure setups. Notes Verify hose outer diameters before installation to ensure a proper fit. Use appropriate clamps and observe pressure and temperature limits of your hoses and system; brass connector is for mechanical joining and does not include pressure ratings. This 1PC 1916mm brass straight 2way barbed reducer connector coupler provides a straightforward, durable solution when you need to join different hose sizes quickly and securely.
