BSP Hose Barb Fittings — Brass & Stainless Steel, Male/Female Thread, Elbow, T, Y, Cross

Match the barb OD (in mm) to your hose's inner diameter (ID). For example, a 6mm barb fits a 6mm ID hose. The BSP thread size (1/8" to 2") should match your port or fitting thread. When in doubt, measure your hose ID with calipers before ordering. A slightly snug fit is normal and helps create a secure seal.

BSP (British Standard Pipe) is a thread standard widely used in plumbing and pneumatic systems across the UK, Europe, Asia, and Australia. BSP and NPT (National Pipe Thread) are generally not interchangeable — they have different thread angles (55° vs 60°) and pitches. Always confirm your port standard before ordering. If you're unsure, check your equipment's manual or measure the thread pitch.

Stainless steel variants are generally suitable for outdoor and wet environments due to their corrosion resistance. Brass fittings are typically used in indoor plumbing, pneumatics, and low-corrosion applications. For marine or highly corrosive environments, stainless steel is the recommended choice. In most cases, both materials perform well in standard garden irrigation and outdoor water line applications.

Pressure ratings vary by size, material, and hose type. Brass fittings typically handle moderate pressures suitable for water, air, and fuel lines. Stainless steel fittings generally support higher pressures. For specific pressure requirements, contact us to confirm before use in high-pressure systems. Always use a hose clamp on barb connections in pressurized applications.

Brass is a cost-effective choice for general plumbing, pneumatics, fuel lines, and indoor water systems. Stainless steel is preferred for food-grade, marine, chemical, or outdoor applications where corrosion resistance is critical. Both materials provide reliable sealing when properly installed with PTFE tape on threaded connections and a hose clamp on barb ends.

For threaded connections (male/female BSP), applying PTFE tape or thread sealant is generally recommended to ensure a leak-free seal. Wrap PTFE tape clockwise around the male thread (typically 2–3 wraps) before assembly. Barb connections should be secured with a hose clamp for best results, especially in pressurized systems.
