Description
Overview:
The Malleable Iron Elbow Male-Female 1/4" BSP (MPN: 686 014) is a right-angle pipe fitting for turning a line through 90 degrees while changing from an external to an internal BSP thread. Made from tough malleable iron, it provides strength with a degree of ductility to resist cracking during installation and service. The 1/4 inch nominal BSP size is approximately 6.35 mm and suits common UK plumbing and plant maintenance tasks. It is used across workshop air systems, water lines, and general-purpose fluid routing on machinery, pumps, and valves. This compact elbow helps with neat, space-saving pipe runs in confined areas on equipment such as air compressors and pressure-washing rigs, as well as in building services and agricultural setups.
Key Features:
- 90-degree male (external) to female (internal) 1/4" BSP connection, nominally 1/4 inch ≈ 6.35 mm for standard UK pipework
- Malleable iron construction for durability and impact resistance under typical installation loads
- Reliable thread engagement for a secure seal when used with PTFE tape or approved thread sealant
- Compact elbow form factor helps achieve tight turns where space is limited
- Compatible with common plumbing and maintenance tasks on tools, machinery, and plant equipment
- Suitable for water and air systems and other non-corrosive media typically used with malleable iron fittings
- Simple to fit and remove with standard hand tools, supporting straightforward maintenance
- Engineered for consistent connection quality to minimise leaks and improve system efficiency
Typical Applications:
Used to re-route pipework around obstacles or into equipment ports on air compressor lines, workshop airlines, coolant and water supply lines, irrigation manifolds, pressure gauges, pumps, valves, and general plant maintenance. Helpful for creating neat right-angle connections on benches, skids, cabinets, and machine frames where a male-to-female 1/4" BSP elbow is required.
