Reduction coupling Lightwin DC 12/10MM Red — 12 mm to 10 mm pipe connector

Reduction coupling Lightwin DC 12/10MM Red is a compact connector designed to join 12 mm and 10 mm diameter tubing. The red coupling provides a reliable transition between different pipe sizes in fluid or low-pressure air systems and is suitable for repairs, extensions or modifications of existing lines, ensuring a secure fit for compatible 12 mm and 10 mm hoses.

Advantages

The Lightwin reduction coupling is compact, colour-coded for easy identification and manufactured to fit standard 12 mm and 10 mm tubing. Its simple push-fit design reduces installation time and provides a stable connection for low-pressure applications without additional tools.

Suitable for

• Repairing damaged 12 mm or 10 mm hoses
• Extending tubing runs with mixed diameters
• Modifying fluid lines in irrigation, aquariums or low-pressure pneumatic systems

Key specifications

• Brand: Lightwin
• Model / MPN: DC 12/10MM RED
• Material: compatible with standard plastic tubing (see hose compatibility)
• Connection: reduction coupling from 12 mm to 10 mm
• Colour: red

How to use

Ensure both tubes are clean and cut square. Push the 12 mm tube fully onto the larger end of the coupling and the 10 mm tube onto the smaller end until each tube is seated firmly. Verify the connection by gently pulling each hose to confirm a secure fit. For long-term or pressurised installations, check compatibility of tubing material and operating conditions before use.

Usage recommendations

Use the Lightwin DC 12/10MM Red coupling in low-pressure fluid or air systems only; avoid exposure to high temperatures or excessive mechanical stress. Inspect connections periodically and replace the coupling if any leakage or damage is detected.
