304 Stainless Steel BSP Male Female Straight Pipe Fitting 1/4" to 2"

Measure the outer diameter of your pipe threads and match it to the BSP nominal size. As a general guide:

• 1/4" BSP — typically 13.16mm (≈0.52") thread OD
• 1/2" BSP — typically 20.96mm (≈0.83") thread OD
• 3/4" BSP — typically 26.44mm (≈1.04") thread OD
• 1" BSP — typically 33.25mm (≈1.31") thread OD
• 2" BSP — typically 59.61mm (≈2.35") thread OD

Always verify with a thread gauge or caliper before ordering. If you're unsure, contact us with your measurements.

304 stainless steel BSP fittings generally handle working pressures up to 150 PSI (approximately 10 bar) in standard plumbing applications. For high-pressure hydraulic or industrial systems, please contact us to confirm suitability for your specific operating conditions.

Yes. 304 stainless steel offers good corrosion resistance in most outdoor and wet environments, including garden irrigation, outdoor water lines, and exposed pipe runs. For highly corrosive settings — such as coastal, marine, or chemical-exposure environments — 316 stainless steel is generally recommended instead.

Yes. These fittings use British Standard Pipe (BSP) threads, which are widely used in plumbing, gas, and hydraulic systems across the US, UK, Australia, and many other countries. They are not directly compatible with NPT (National Pipe Thread) fittings — the thread angle and pitch differ. A BSP-to-NPT adapter is required if connecting to an NPT system.

Yes. For a leak-free seal, applying PTFE thread seal tape or a suitable pipe thread sealant compound to the male threads before assembly is generally recommended — especially for water and gas lines. Wrap PTFE tape clockwise (when facing the thread end) for 2–3 layers before threading the fitting in.

The 1/2" Hexagonal Female×Male variant features a hex body profile that allows you to grip and tighten the fitting with a standard wrench or adjustable spanner, making installation easier in tight spaces or high-torque applications. The standard round-body 1/2" version is typically used where wrench access is not a concern and hand-tightening plus PTFE tape is sufficient.

304 stainless steel BSP fittings are commonly used in natural gas and LPG pipe systems. However, always verify local building codes and regulations before installing any fitting on a gas line, and use a gas-rated thread sealant compound (not standard PTFE tape alone, in many jurisdictions). When in doubt, consult a licensed gas fitter.
