Metric PVC-U Reducing Bush

Engineered to fit inside a larger fitting socket, the reducing bush connects a smaller diameter pipe or threaded component directly into the system, keeping flow consistent and the line pressure intact. Certain variants also convert a solvent weld metric socket into a BSP threaded connection, making it easy to integrate valves, taps, or instrumentation without reworking the surrounding pipework.

Built from unplasticised polyvinyl chloride, this bush holds its own against corrosive chemicals, aggressive fluids, and the demands of industrial environments. Bond it in place with standard PVC solvent cement and you have a permanent, watertight joint rated to withstand up to 15–16 bar of pressure,- reliable enough for high stakes applications in chemical processing, water treatment, and industrial plumbing.

Compact, chemically resistant, and straightforward to install, the Metric PVC-U Reducing Bush is the dependable solution for stepping down pipeline sizes without sacrificing system integrity.

Summary: 

• A metric PVC-U reducing bush is used to connect a smaller metric plastic pipe or threaded component into a larger socket on a PVC-U fitting
• Steps down the size of the pipeline smoothly while keeping the system strong and watertight
• Fits inside a larger fitting socket to let you attach a smaller diameter pipe
• Some types convert a solvent-weld metric socket into a smaller threaded (BSP) connection for valves or taps
• Helps adapt line sizes in industrial, chemical, or water treatment plumbing
• Made of tough, unplasticised polyvinyl chloride (PVC-U), which resists corrosion and chemicals
• Glued in place using PVC solvent cement (glue) for a permanent seal
• Built to handle high-pressure water systems, often rated up to 15 or 16 bar

Applications: 
Commonly used in;

• Purificaiton systems
• Chemical dosing 
• Acid handling
• Plating lines
