Stainless Steel 304 Barb Hose Tail Connector – 1/2" & 3/4" BSP Male Thread Hose Fittings

Match the barb length to your hose's inner diameter (ID). Generally, the barb should be at least as long as the hose ID to ensure a secure grip. For example, a 13mm (≈1/2") barb typically suits 1/2" ID hose, and a 19mm (≈3/4") barb suits 3/4" ID hose. When in doubt, size up — a longer barb provides more surface area for clamping and reduces blow-off risk under pressure.

SS304 barb fittings generally handle working pressures up to 150 PSI (≈10 bar) in low-to-medium pressure fluid transfer applications when properly clamped with a hose clamp. Actual ratings depend on hose material, clamp type, fluid temperature, and installation quality. Contact us to confirm for your specific use case.

Yes. 304 stainless steel offers good corrosion resistance against moisture, mild chemicals, and atmospheric exposure, making it suitable for outdoor irrigation, garden plumbing, and light marine freshwater applications. For highly saline or chlorinated environments (e.g., saltwater marine), 316 stainless steel is typically recommended for longer service life.

These fittings use BSP (British Standard Pipe) male thread — either 1/2" BSP or 3/4" BSP. BSP threads are widely used in plumbing, hydraulics, and pneumatic systems in the UK, Europe, Australia, and Asia. They are not directly compatible with NPT (National Pipe Thread) used in North American plumbing without a BSP-to-NPT adapter. Check your port standard before ordering.

Yes, for a leak-free seal we recommend applying 2–3 wraps of PTFE tape to the male BSP thread before installation. For parallel BSP (BSPP) threads, a bonded seal washer or O-ring at the thread face is also commonly used. Do not overtighten — hand-tight plus 1–2 turns with a wrench is generally sufficient for most BSP fittings.

SS304 barb fittings are generally compatible with water, air, mild oils, and non-aggressive chemicals. They are not recommended for strong acids, high-concentration chlorides, or highly alkaline solutions. Always verify chemical compatibility for your specific fluid and operating conditions before installation.

Each listing offers quantity options of 1, 2, 3, 5, 8, 10, 15, or 20 pieces. Select your required quantity from the Quantity(PCS) dropdown before adding to cart. Larger quantity variants offer better per-unit value for trade, maintenance, or project use. For quantities beyond 20 pieces, contact us for a custom quote.

For pressurized applications, a hose clamp (worm-drive or ear clamp) is strongly recommended over the barb tail to prevent hose blow-off. For low-pressure or gravity-fed systems, a push-on connection may be sufficient, but clamping is always best practice for reliable, long-term performance.
