Brass BSP Straight Pipe Fitting — Reliable Female-to-Male Thread Connector for Plumbing & Pneumatic Systems

When a leaking joint or a mismatched pipe run brings your project to a halt, you need a fitting you can trust to seal tight and stay that way. Whether you're a plumber routing water lines, a workshop owner building an air compressor manifold, or a DIYer extending a gas or hydraulic circuit, these brass BSP straight pipe fittings deliver the thread accuracy and material integrity that professionals depend on.

Each fitting is a straight female-to-male BSP thread connector machined from solid brass. Available in three thread diameters — 1/8" (≈9.7mm OD), 1/4" (≈13.2mm OD), and 3/8" (≈16.7mm OD) — and five body lengths from 50mm (≈2") to 150mm (≈6"), these connectors let you bridge gaps, extend runs, or adapt port depths with precision. Order in quantities of 1, 2, 5, or 10 pieces to match your project scale.

Typical use cases include extending water supply lines behind walls, connecting pneumatic tool circuits in workshops, linking hydraulic fittings on machinery, and building custom fluid-transfer manifolds. The BSP (British Standard Pipe) thread form is widely recognized in US, UK, European, and Asian plumbing and industrial systems, making these fittings a versatile choice for both domestic repairs and light industrial installations.

🔗 Thread Compatibility: BSP (British Standard Pipe / G-thread / Whitworth). Not directly compatible with NPT threads — an adapter is required for NPT systems.

✅ Key Features of These Brass BSP Straight Female x Male Pipe Fittings

  • 🔩Precision BSP Thread Form — Machined to BSP (G-thread) standards for accurate thread engagement and a consistent, leak-resistant fit in plumbing and pneumatic pipe fittings applications.
  • 🟡Solid Brass Construction — Brass offers natural corrosion resistance to water, air, and mild chemicals, making these straight pipe connectors suitable for both indoor plumbing and sheltered outdoor installations.
  • 📏Wide Size Range — Available in 1/8", 1/4", and 3/8" BSP thread diameters with body lengths from 50mm to 150mm, covering the most common female-to-male thread connector needs in one product line.
  • 🔄Straight Female x Male Design — The inline female-in / male-out configuration makes these fittings ideal for extending pipe runs, bridging port gaps, or converting between fitting depths without changing flow direction.
  • 🛠️Tool-Ready Hex Body — The fitting body is typically shaped for wrench engagement, allowing controlled torque during installation and reducing the risk of over-tightening or thread damage.
  • 📦Flexible Pack Quantities — Choose 1, 2, 5, or 10 pieces per order so you can stock exactly what your repair, build, or maintenance job requires — no excess inventory, no last-minute hardware runs.
⚠️ Installation Note: Always apply PTFE tape (2–3 wraps) or a compatible thread sealant to the male threads before assembly. BSP parallel threads require a face seal or sealant for a leak-free connection.

❓ Frequently Asked Questions

How do I choose the right length for my pipe fitting?

Measure the gap between your two pipe ends or the depth of the port you need to bridge. As a general rule, add 10–15mm to account for thread engagement on both ends. For reference: 50mm ≈ 2", 75mm ≈ 3", 100mm ≈ 4", 125mm ≈ 5", 150mm ≈ 6". When in doubt, choose the next size up — it's easier to trim a run than to extend it.

What thread standard do these fittings use?

These fittings use BSP (British Standard Pipe) threads, also known as G-thread or Whitworth pipe thread. BSP is widely used in plumbing, pneumatics, and hydraulics across the US, UK, Europe, and Asia. It is not directly compatible with NPT (National Pipe Taper) threads without an adapter.

Can these fittings be used outdoors or in wet environments?

Brass generally offers good corrosion resistance for most indoor and sheltered outdoor applications involving water, air, and mild chemicals. For prolonged direct exposure to saltwater or highly acidic environments, stainless steel fittings are typically recommended. Always apply PTFE tape or thread sealant to ensure a watertight seal.

What is the pressure rating of these brass pipe fittings?

Brass BSP fittings of this type are generally rated for working pressures up to 150–200 PSI (approximately 10–14 bar) in water and air service at ambient temperatures. Actual ratings depend on the specific size and installation conditions. Contact us to confirm if your application requires a specific pressure certification.

Are these fittings compatible with copper, steel, or plastic pipes?

Yes — as long as the mating pipe or port uses BSP threads, these fittings are compatible with copper, steel, brass, and many plastic pipe systems. For plastic pipes, check that the pipe's thread standard is BSP (G-thread) and not NPT or metric before ordering.

Do I need thread sealant with these fittings?

Yes. BSP parallel threads (BSPP/G-thread) rely on a face seal or thread sealant for a leak-free connection. We recommend wrapping the male threads with 2–3 layers of PTFE tape before assembly. For higher-pressure applications, a liquid thread sealant compound is generally preferred.

Which size should I choose — 1/8", 1/4", or 3/8"?

Match the thread size to your existing pipe or port. Use a thread gauge or measure the outer diameter of the male thread: 1/8" BSP ≈ 9.7mm OD, 1/4" BSP ≈ 13.2mm OD, 3/8" BSP ≈ 16.7mm OD. If unsure, check the markings on your existing fittings or consult your equipment manual.
