Description
Overview:
The Extension Tube 4" x 1/2" BSP (MPN 816 412) is a threaded metal spacer for extending or bridging gaps between pipe fittings in plumbing, air, fuel, and oil systems. At 4 inches (approximately 10.16 cm) long with 1/2 inch (approximately 12.7 mm nominal) BSP connections, it allows you to position components such as valves, gauges, filters, and hoses for better access, serviceability, or heat separation. Precision-machined threads help maintain a tight, leak-resistant seal when used with suitable sealing methods. Built for everyday site and workshop use, it is a practical choice for machinery pipework, plant maintenance, and static installations where reliable alignment and spacing are needed. Suitable for use across a wide range of tools and machines including pumps and compressors.
Key Features:
- 4 inch (approx. 10.16 cm) extension length for simple spacing and alignment tasks
- 1/2 inch BSP threaded connections for compatibility with common UK pipework
- Durable metal construction for demanding environments in plumbing and industrial systems
- Supports air, fuel, oil, and water service when used with appropriate sealing and materials
- Helps relocate components away from heat, vibration, or obstructions for safer access
- Straightforward to install with standard spanners and BSP fittings
- Clean, consistent threads for secure, leak-resistant joints
- Useful for repairs, retrofits, and upgrades without reworking existing pipe runs
- Compact form factor to fit tight spaces on machinery and plant
- MPN 816 412 for easy identification and re-ordering
Typical Applications:
Used to extend pipework on machinery and plant, connect remote-mounted gauges or valves, create stand-off spacing from hot engines or enclosures, and improve service access in compressed air lines, lubrication circuits, diesel/kerosene fuel lines, and general plumbing. Ideal for workshops, site equipment, generators, small pumps, and fixed installations where a short, rigid extension is required without altering the main pipe route.
Also known as:
Pipe extender, extension nipple, threaded extension tube, fitting extension, BSP tube spacer, stand-off tube, tube connector, plumbing extension, BSP connector, threaded pipe spacer. These terms are often used interchangeably for short, rigid, 1/2 inch BSP extensions used to bridge gaps between standard fittings.
