Description
Overview:
The Malleable Male-Female Reducing Hex Bush 3/8"m x 1/4"f BSP is a compact threaded adaptor for joining different pipe sizes in fluid and air systems. Made from tough malleable iron with a corrosion-resistant galvanised finish, it reduces from a 3/8 inch (approx. 9.5 mm) male BSP thread to a 1/4 inch (approx. 6.35 mm) female BSP thread. The hexagonal body makes tightening and removal straightforward with a spanner. It is suited to plumbing, workshop, and plant equipment where reliable BSP connections are required, such as compressors, water pumps, pressure washers, and general pneumatic lines. The bush provides a neat, space-saving reduction while maintaining a secure, leak-resistant joint when installed correctly. Manufacturer Part Number (MPN): 383 314.
Key Features:
- Durable malleable iron body for long service life in workshop and site conditions
- Galvanised finish for improved resistance to rust and general corrosion
- 3/8" (approx. 9.5 mm) male BSP to 1/4" (approx. 6.35 mm) female BSP for common UK pipework transitions
- Hex head profile for easy fitting and removal with standard spanners
- Compact one-piece reducer saves space versus multi-fitting assemblies
- Suitable for air, water, and non-corrosive fluids in compatible systems
- BSP threading for broad compatibility with UK hoses, valves, and fittings
- Clean, well-formed threads to help achieve a tight, dependable seal
- Works with typical sealing methods such as PTFE tape or pipe thread sealant
- Practical choice for both trades and DIY where a simple size reduction is needed
Typical Applications:
Commonly used to adapt down from 3/8" BSP pipework to 1/4" BSP accessories on compressors, air tools, pressure washers, irrigation lines, dosing and metering systems, and general plant maintenance. Useful in confined areas where a short, rigid reducer is preferred over couplings and nipples.
