Description
Overview:
The Malleable Iron Elbow Male-Female 4" BSP is a heavy-duty threaded pipe fitting for building reliable pipe runs on site, in workshops, and in plant rooms. Cast from malleable iron for toughness and shock resistance, it joins two 4-inch (101.6 mm) BSP-threaded connections at an angle while allowing a direct male-to-female join without a separate coupling. It is well suited to water, air, and many non-corrosive fluids commonly encountered around pumps, compressors, irrigation sets, and industrial equipment. The robust construction handles everyday vibration and handling in both residential and commercial plumbing layouts. Use it to turn lines neatly where space is tight or where a strong, rigid joint is needed in steel or iron pipework with British Standard Pipe threads.
Key Features:
- Malleable iron body for strength, impact resistance, and long service life
- 4" (101.6 mm) BSP threaded ends for UK-standard compatibility across many systems
- Male one end and female the other for direct connection without an extra coupling
- Clean, accurately cut threads to help achieve a secure, leak-resistant joint
- Suitable for water, air, and many non-corrosive fluids in general service pipework
- Helps create tight bends in restricted spaces while keeping flow paths consistent
- Withstands typical site conditions, vibration, and handling in daily use
- Simple to install with standard tools; use PTFE tape or an appropriate jointing compound
Typical Applications:
Turning 4" (101.6 mm) BSP pipe runs around corners on plant, in boiler rooms, or along walls; connecting to pumps, tanks, compressors, and manifolds; routing irrigation and site water lines; adapting process lines in workshops and factories; making durable changes in direction on heating return lines and general plumbing where threaded iron pipe is in use.
