Description
Overview:
This Malleable Male-Female Reducing Hex Bush is a heavy-duty BSP fitting used to step down from a 3 inch (76.2 mm) male thread to a 2 inch (50.8 mm) female thread. Made from tough malleable iron for dependable service life, it is designed for pipework where a secure, threaded reduction is required. The hexagonal body allows firm tightening with a spanner, helping achieve a tight, reliable joint in building services, workshop pipework, and on-site installations. Suitable for general plumbing and plant maintenance, it connects differing pipe sizes cleanly without adding unnecessary length. Commonly used with steel and other BSP-threaded fittings, it supports efficient flow transitions and tidy layouts. Supplied under MPN 383 302 for easy identification and reordering.
Key Features:
- Robust malleable iron construction for strength and long service life
- BSP threads: 3 inch (76.2 mm) male to 2 inch (50.8 mm) female for standardised compatibility
- Hexagonal profile for positive grip and straightforward installation/removal with standard tools
- Compact reducer design helps keep assemblies short and rigid
- Assists in achieving leak-tight joints when used with suitable BSP thread sealant or PTFE tape
- Suitable for residential, commercial, and industrial pipework where a size reduction is needed
- Reusable component that can be serviced or repositioned during system changes
- MPN 383 302 for straightforward specification and spares control
- Compatible with a wide range of BSP valves, tees, elbows, and manifolds
- Ideal for water and general-purpose utility lines in plant rooms and workshops
Typical Applications:
Reducing large-bore lines to smaller downstream equipment, connecting pumps or tanks to existing pipework, adapting manifolds, branch take-offs, and service points, workshop and site utility lines, irrigation and general plumbing layouts, and maintenance tasks where a 3 inch BSP male connection must be reduced to a 2 inch BSP female thread without complex alterations.
