Stainless Steel Hose Barb Tail Fitting — BSP Male Thread Connector Adapter

Match the barb diameter to your hose's inner diameter (ID). For example, a 1/2" barb generally fits a hose with a 1/2" ID. The BSP male thread size should match your port or fitting. When in doubt, measure both the hose ID and the port thread before ordering. A thread gauge or caliper makes this straightforward.

These fittings use BSP (British Standard Pipe) male thread, also known as G-thread or Whitworth pipe thread. BSP is widely used in plumbing, pneumatic, and hydraulic systems in the UK, Europe, Asia, and Australia. If your system uses NPT (National Pipe Thread, common in North America), these fittings are generally not directly compatible without a BSP-to-NPT adapter.

Yes. Stainless steel construction provides strong resistance to rust, oxidation, and mild chemical exposure, making these fittings generally well-suited for outdoor, marine, and humid environments. For highly aggressive chemicals or saltwater immersion, confirm compatibility with your specific application before installation.

Working pressure varies by size and the hose/clamp combination used. Stainless steel hose barb fittings in this style typically handle up to 150–300 PSI in most configurations, but this depends on the hose material and clamp type. Always verify the pressure rating against your system requirements. Contact us to confirm the rating for your specific size.

For most pressurized applications, yes — a hose clamp is strongly recommended. The barbed tail grips the hose interior and resists pull-out, but a clamp adds mechanical retention and helps maintain a leak-free seal under pressure or vibration. For low-pressure or gravity-fed systems, the barb alone may be sufficient.

Stainless steel hose barb fittings are generally compatible with water, air, oil, fuel, and many mild chemicals. Common uses include irrigation systems, compressed air lines, fuel transfer, coolant routing, and industrial fluid handling. For aggressive solvents, strong acids, or highly corrosive media, confirm material compatibility before use.

Yes, in most cases. BSP parallel threads (BSPP/G) do not seal on the thread taper and require PTFE tape or a thread sealant compound to achieve a leak-free connection. BSP tapered threads (BSPT) can seal on the taper, but sealant is still recommended for reliability. Apply 2–3 wraps of PTFE tape in the direction of the thread before assembly.
