Description
Overview:
This malleable iron reducing hex bush is a male-to-female adaptor for BSP pipework. It steps down a 1.1/2 inch (38.1 mm) male BSP connection to a 1 inch (25.4 mm) female BSP thread, allowing different pipe or component sizes to be joined securely. The hexagonal body provides a solid spanner grip for straightforward tightening and removal in tight spaces. Built for dependable service in plumbing, industrial setups, and machinery maintenance, it suits construction and garden equipment such as pumps, compressors, pressure washers, and water systems that use BSP fittings. The robust malleable iron construction offers strength and durability under routine mechanical stress, with a clean grey metal finish and well-cut threads to help achieve a reliable, leak-tight joint when fitted with an appropriate thread sealant.
Key Features:
- Reduces from 1.1/2 inch (38.1 mm) male BSP to 1 inch (25.4 mm) female BSP
- Malleable iron body for high strength and impact resistance in everyday use
- Hexagonal shape for secure spanner or socket engagement and easy installation
- Smooth, accurate BSP threads to support leak-tight joints with PTFE tape or thread sealant
- Compact fitting that saves space in manifolds, pump housings, and tight pipe runs
- Suitable for water, air, and compatible oils within typical BSP pipework systems
- Good wear and corrosion resistance to support long service life in workshop and site conditions
- Helps adapt legacy or oversized ports to modern pipe sizes without reworking the system
- Reusable if threads remain undamaged and sealing surfaces are clean
- Widely compatible with standard BSP valves, filters, gauges, and pipe sections
Typical Applications:
Adapting ports on pumps, compressors, and pressure control equipment; stepping down connections on water lines, compressed air circuits, and general service pipework; connecting BSP accessories such as gauges, valves, and filters; maintenance and repairs on construction plant and garden machinery where a larger BSP outlet must be reduced to a smaller BSP fitting.
Also known as:
Reducing hex bush, BSP bush, hex reducer, reducing bushing, male-to-female reducer, MF reducing bush, pipe reducer bush, hexagonal bush fitting, BSP adaptor bush.
