{"product_id":"hydroponic-tub-outlet-13mm-19mm-25mm","title":"Hydroponic Tub Outlet | 13mm, 19mm \u0026 25mm Tank \u0026 Reservoir Bulkhead Fittings","description":"\u003cp\u003eEvery hydroponic reservoir, grow tray, and nutrient tank needs a reliable exit point for water and nutrient solution. Without a properly sealed outlet, you're relying on improvised connections that leak, fail under pressure, or require constant attention. Hydroponic tub outlets solve this at the source, creating a permanent, watertight connection point through the wall of any container so your irrigation system can run cleanly and consistently without intervention.\u003c\/p\u003e\n\u003cp\u003eAvailable in 13mm, 19mm, and 25mm sizes, these bulkhead-style fittings install through a drilled hole in your tank or tray wall and lock into place with a threaded nut and rubber seal. The barbed outlet connects directly to standard hydroponic irrigation tubing, giving you a secure, leak-resistant flow path for gravity-fed drainage, pump-driven recirculation, or flood and drain cycle management. A straightforward fitting that underpins the reliability of your entire system.\u003c\/p\u003e\n\u003ch2\u003eHow It Works\u003c\/h2\u003e\n\u003cp\u003eInsert the fitting through the correct size drilled hole in your tank, reservoir, or grow tray wall. Thread the locking nut onto the fitting from the outside and tighten against the rubber seal to create a watertight bulkhead connection. Push your irrigation tubing onto the barbed outlet to complete the connection. The barbed design grips the inner wall of the tubing to prevent pull-out under normal operating pressure, maintaining a consistent, leak-free flow path for the life of your system.\u003c\/p\u003e\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable in 13mm, 19mm, and 25mm sizes.\u003c\/strong\u003e Covers the full range of standard hydroponic tubing sizes, from small feeder lines through to high-flow main supply lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeak-resistant bulkhead fitting design.\u003c\/strong\u003e Threaded body with rubber seal creates a watertight connection through container walls, eliminating the slow drips that undermine system reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarbed outlet for secure tubing connection.\u003c\/strong\u003e Barbed design grips irrigation tubing firmly to prevent pull-out and maintain consistent flow under pump pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for tanks, reservoirs, and grow trays.\u003c\/strong\u003e Installs in any container with a drilled hole, making it compatible with a wide range of hydroponic system configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports gravity-fed and pump-driven systems.\u003c\/strong\u003e Works equally well as a drain outlet, a pump inlet connection, or a flood and drain system fitting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable high-strength polymer construction.\u003c\/strong\u003e Built for long-term use in nutrient-rich hydroponic environments across multiple grow cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy installation with threaded locking system.\u003c\/strong\u003e No specialist tools required, \u003cspan style=\"text-decoration: underline;\"\u003ebesides a drill for the hole\u003c\/span\u003e. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHydroponic reservoir and nutrient tank outlet connections\u003c\/li\u003e\n\u003cli\u003eGrow tray drainage and flood and drain system plumbing\u003c\/li\u003e\n\u003cli\u003eDrip irrigation tank inlet and outlet fittings\u003c\/li\u003e\n\u003cli\u003eRecirculating hydroponic system connections\u003c\/li\u003e\n\u003cli\u003eGreenhouse irrigation tank plumbing\u003c\/li\u003e\n\u003cli\u003eNutrient solution transfer between containers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes.\u003c\/strong\u003e 13mm \/ 19mm \/ 25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type.\u003c\/strong\u003e Barbed outlet with threaded bulkhead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes.\u003c\/strong\u003e Threaded bulkhead body, locking nut, rubber seal\/gasket, barbed outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial.\u003c\/strong\u003e High-strength polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction.\u003c\/strong\u003e Tank outlet and inlet connection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication.\u003c\/strong\u003e Hydroponics, irrigation, fertigation systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironment.\u003c\/strong\u003e Indoor, greenhouse, commercial systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight.\u003c\/strong\u003e Approx. 0.05 to 0.15 kg per unit (size dependent)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Bought Together\u003c\/h2\u003e\n\u003cp\u003eTub outlets work as part of a complete plumbing setup.
