BSP Male Thread Barb Hose Tail Connector 304 Stainless Steel — 1" to 3"

Match the BSP thread size (e.g., 1" BSP) to your pipe or valve port, and match the barb diameter to your hose's inner diameter. Generally, the barb OD should be equal to or slightly larger than the hose ID for a secure grip. For example, a 1" BSP connector typically suits hoses with an inner diameter of approximately 25mm (≈1"). When in doubt, measure your hose ID with calipers before selecting a size.

304 stainless steel barb fittings are generally rated for working pressures up to 150 PSI (≈10 bar) in typical low-to-medium pressure fluid and air systems. Actual ratings depend on hose type, clamp method, and fluid temperature. For high-pressure applications, contact us to confirm suitability for your specific system.

Yes. 304 stainless steel offers good corrosion resistance in most outdoor environments, including freshwater irrigation systems, garden hose connections, and general weather exposure. For saltwater or highly corrosive marine environments, 316 stainless steel is typically recommended. These fittings are not designed for prolonged immersion in chlorinated or acidic solutions.

BSP (British Standard Pipe) and NPT (National Pipe Thread) are not interchangeable. BSP threads have a 55° thread angle and are common in European, Australian, and Asian plumbing systems. NPT threads have a 60° angle and are the North American standard. Forcing BSP fittings into NPT ports (or vice versa) will result in leaks or thread damage. Always verify your port thread standard before ordering.

304 stainless steel is generally suitable for hot water service up to approximately 120°C (248°F). For compressed air applications, these fittings are typically compatible with standard shop air pressures (up to 150 PSI in most cases). For steam lines or high-temperature/high-pressure systems, consult your system specifications and confirm with us before ordering.

For any pressurized application — including water, air, or fluid transfer lines — a hose clamp (worm-drive or crimp-style) is strongly recommended. The clamp prevents the hose from blowing off the barb under pressure. For gravity-fed or very low-pressure systems, a tight-fitting hose may hold without a clamp, but clamping is always the safer and more reliable practice.

304 stainless steel is compatible with water, air, mild acids, oils, and many non-chlorinated chemicals. It is generally not recommended for chlorine-rich solutions, bleach, or highly concentrated acidic environments. Always verify chemical compatibility using a material compatibility chart for your specific fluid before installation.
