BSP 90° Elbow Barbed Hose Fitting — 304 Stainless Steel Pipe Connector

Match the barb diameter to your hose's inner diameter (ID). For example, an 8mm barb is typically used with 5/16" ID hose, a 10mm barb with 3/8" ID hose, and a 12mm barb with 1/2" ID hose. When in doubt, measure your hose ID with calipers before ordering — a barb that's slightly larger than the hose ID generally creates a tighter seal.

BSP (British Standard Pipe) refers to the threaded end that screws into your pipe port or fitting. The size (e.g., 1/4" BSP, 3/8" BSP) indicates the nominal pipe thread diameter — not the actual measured diameter of the threads. This must match the female BSP port on your pump, valve, tank, or manifold. BSP is widely used in plumbing, irrigation, and industrial fluid systems outside of North America, and is also common in imported equipment sold in the US.

Yes, 304 stainless steel is generally well-suited for outdoor and wet environments due to its corrosion resistance. It performs well in garden irrigation, outdoor plumbing, and automotive applications exposed to water and humidity. For highly saline or chlorinated environments — such as marine or pool applications — 316 stainless steel is typically recommended for superior corrosion resistance.

304 stainless steel barbed fittings are generally rated for moderate working pressures in typical plumbing and irrigation applications. The actual pressure capacity depends on the hose type, wall thickness, clamp used, and installation method. For high-pressure hydraulic or pneumatic systems, consult your system's pressure specifications and verify the fitting's rated pressure before use.

For most pressurized applications, a hose clamp is strongly recommended to ensure a leak-free, pull-resistant connection. The multi-ribbed barb design provides a mechanical grip on the hose inner wall, but a clamp adds a secondary retention layer that is especially important under pressure, vibration, or thermal cycling. For low-pressure gravity-fed systems, the barb alone may be sufficient.

These fittings typically use BSPP (parallel) thread on the male end. BSPP threads rely on a washer or O-ring at the port face for sealing, rather than thread taper. If your system uses BSPT (tapered) thread, please contact us to confirm compatibility before ordering, as mixing parallel and tapered BSP threads can result in poor sealing.

304 stainless steel is generally compatible with water, coolant, mild chemicals, and some fuels. However, compatibility depends on the specific fluid, concentration, temperature, and pressure. Always verify chemical compatibility with your particular fluid before use. For aggressive chemicals or fuels, consult a materials compatibility chart or contact us for guidance.
