Description
A PVC Adaptor reducing bush 25mm x 3/8″ with a BSP (British Standard Pipe) thread. Is a fitting used in plumbing and irrigation systems. To connect pipes and fittings of different sizes. It has a plain (non-threaded) end that can be solvent-welded into a larger PVC fitting. Also a female BSP threaded end to connect with a smaller, threaded fitting.
Features and uses
- Function: A reducing bush provides a smooth transition from a larger pipe or fitting to a smaller one, minimizing turbulence and ensuring proper flow.
- Connection: This type of adapter is designed to connect a plain-ended PVC pipe to a standard British Standard Pipe (BSP) threaded fitting. It provides versatility for joining different connection types.
- Durability: Since it’s made from high-quality PVC-U (unplasticised polyvinyl chloride), it offers strong resistance to corrosion, chemicals, and impact damage.
- Applications: Common uses include potable water systems, irrigation, drainage, and industrial fluid handling.
- Installation: The plain end of the reducing bush is installed using a solvent weld (PVC pipe glue) into the larger fitting. The threaded end can then be connected to a smaller threaded pipe or fitting.

- PVC Reducing Bush Threaded: Used to convert from a larger threaded fitting to a smaller one. It connects to standard BSP threaded fittings.
Finally how to choose the right reducing bush
When selecting a reducing bush, you should confirm the following details:
- Connection type: Determine if you need a plain (solvent weld) or threaded connection for both the larger and smaller pipes.
- Pipe dimensions: Ensure the bush matches the internal and external diameters of the pipes and fittings you are connecting.
- Pressure rating: Check the pressure rating of the fitting, often noted as PN followed by a number, to make sure it is suitable for your application.
- Material: The most common material is PVC, but other options like nylon or polypropylene (PP) are also available for different applications.
