304 Stainless Steel Y-Piece 3-Way Hose Barb Fitting | BSP Thread Pipe Connector

Match the barb diameter to your hose's inner diameter (ID). For example, a Ø6mm barb is typically used with 6mm ID hose. Measure your hose ID before ordering. Available sizes range from Ø6mm (≈1/4") to Ø25mm (≈1"). When in doubt, size down slightly — a snug fit creates a better seal than a loose one.

304 stainless steel hose barb fittings generally handle working pressures up to 150 PSI in typical fluid transfer applications, though actual ratings depend on hose type, clamp method, and fluid temperature. For high-pressure systems, confirm compatibility with your system specs before installation.

Yes. 304 stainless steel offers good corrosion resistance in most outdoor and mildly saline environments. For highly aggressive marine or chemical environments, 316 stainless steel is generally recommended. These fittings are suitable for garden irrigation, outdoor plumbing, and light marine applications.

These fittings use BSP (British Standard Pipe) thread, which is widely used in plumbing and fluid systems across the UK, Australia, and Asia. BSP is not directly interchangeable with NPT (US standard) — thread pitch and angle differ. If your system uses NPT fittings, a BSP-to-NPT adapter will be required. Please confirm your thread standard before ordering.

For low-pressure or gravity-fed systems, a push-fit connection may hold adequately. For pressurized lines, using stainless steel hose clamps is strongly recommended to prevent blowoff and ensure a leak-free seal. Clamps are not included and should be purchased separately.

304 stainless steel is generally compatible with water, mild acids, oils, and many common fluids. For fuel lines, chemical transfer, or food-grade applications, verify that 304 SS meets your specific fluid compatibility requirements.

These Y-piece barb fittings are compatible with flexible hoses including silicone hose, PVC tubing, rubber hose, and braided hose — provided the hose inner diameter matches the barb size. Rigid pipe connections are not suitable for barb-style fittings.

Here are the approximate inch equivalents for each available size: Ø6mm ≈ 1/4", Ø8mm ≈ 5/16", Ø10mm ≈ 3/8", Ø12mm ≈ 1/2", Ø13mm ≈ 1/2", Ø15mm ≈ 5/8", Ø20mm ≈ 3/4", Ø25mm ≈ 1". Always verify against your hose's actual inner diameter measurement rather than relying solely on nominal size labels.
