Whether you're routing a gas line in a workshop, connecting a coolant hose in an engine bay, or building a fluid transfer system, you need a fitting that holds tight and won't rust out after a season. These stainless steel female threaded hose barb fittings are built for exactly that — delivering a secure, corrosion-resistant connection between threaded ports and flexible hoses.\u003c\/p\u003e\n    \u003cp\u003eEach fitting features a female threaded inlet and a barbed tail outlet. The female thread sizes range from 1\/4\" to 3\/4\", and barb lengths are available from 8mm (≈5\/16\") to 25mm (≈1\"). The barbed tail is designed to grip the inner wall of flexible hose tubing, while the female thread connects directly to a male-threaded port or valve. Available in multiple size combinations to match your specific hose and port dimensions.\u003c\/p\u003e\n    \u003cp\u003eThese female threaded hose barb connectors are well-suited for low-pressure gas line connections in workshop equipment, water line routing in irrigation and plumbing systems, and coolant or air hose connections in automotive and industrial setups — anywhere a secure barb-to-thread transition fitting is needed.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility Note:\u003c\/strong\u003e Female thread end is generally compatible with NPT male-threaded ports (1\/4\", 3\/8\", 1\/2\", 3\/4\").
