Description
Overview:
The Weldable Malleable Iron Female Socket 3/8" BSP is a robust pipe fitting designed to create strong, permanent connections on steel and iron pipework. Made from black malleable cast iron, it combines good mechanical strength with shock resistance, making it suitable for demanding environments. The female threaded end accepts a standard 3/8 inch (9.5 mm) BSP connection, while the plain exterior allows the socket to be welded to compatible pipe or fabrications for a secure, leak‐resistant joint. It is commonly used across plumbing, compressed air, water, oil, and general industrial services, as well as on plant and workshop installations for construction and garden machinery support equipment such as compressors and pressure-wash systems. Reliable, simple to fit, and built for long service.
Key Features:
- Weldable design for permanent attachment to steel or iron pipework, providing a rigid and leak-resistant joint
- Female 3/8" BSP thread compatible with standard fittings and accessories; imperial size stated alongside metric 9.5 mm
- Manufactured from durable malleable cast iron for high strength, impact resistance, and long service life
- Black (uncoated) finish suitable for welding without the issues associated with plated or galvanised coatings
- Straight cylindrical form factor for easy alignment and accurate positioning during fit-up
- Suitable for air, water, and non-corrosive fluid services in industrial, agricultural, and domestic settings
- Simple installation with standard welding practices and common BSP tools for assembly
- Good thermal tolerance typical of malleable iron, aiding performance in workshop and plant environments
- Compact size ideal where space is limited or assemblies need to remain serviceable
- Manufacturer Part Number (MPN): 181 038
Typical Applications:
Used to join a 3/8 inch (9.5 mm) BSP male-threaded fitting to a welded pipe run on site-built manifolds, header lines, compressor outlets, washdown systems, coolant or irrigation pipework, and general plant services. Ideal for maintenance, repair, and upgrade work on industrial piping, workshop air lines, and utility services around construction yards and agricultural facilities.
