3/8" BSP Air Line Fittings

Galvanised Air Line Fittings for Compressed Air Pipework

Galvanised air line fittings are a reliable choice for fixed compressed air pipework where strength, durability and long service life matter. With a protective zinc coating, galvanised fittings are well suited to workshop and industrial environments, helping resist corrosion and general wear over time.

Our range includes a wide selection of BSP threaded fittings for building, extending or repairing airline systems—ideal for creating secure, leak-resistant threaded joints when installed correctly using suitable sealant or PTFE tape.

What You’ll Find in Our Range

• BSP galvanised fittings in multiple sizes (each size has its own dedicated page)
• Reducing fittings to transition between pipe sizes (bushes, nipples, sockets and tees)
• Air pipe brackets to support runs and keep installations neat and secure
• Common fitting types for straight runs, branches, take-offs and system modifications

Where Galvanised BSP Fittings Are Used

Galvanised threaded fittings are commonly used in garage workshops, manufacturing facilities, industrial units and maintenance areas where a permanent compressed air distribution line is required. They’re ideal for installations that need robust connections and easy expansion over time.

Choosing the Right Size

To select the correct fitting size, match the fitting thread to your existing pipework and consider your airflow requirements. Larger bore pipework can help reduce pressure drop over longer distances and support higher-demand tools.
