The Polypipe MU311

 is a 50mm to 40mm solvent weld reducer, a plumbing fitting used to connect pipes of different sizes within a solvent waste system. 

Key Features and Specifications

  • Product Type: Solvent weld waste reducer.
  • Function: Connects a larger 50mm diameter pipe to a smaller 40mm diameter pipe.
  • Material: Made from MuPVC (Modified Unplasticised Polyvinyl Chloride) or ABS, materials known for enhanced impact resistance, flexibility, and the ability to withstand higher temperatures and a broader range of chemicals than standard PVC systems.
  • Connection Type: Requires solvent cement for jointing, creating a permanent, leak-free connection. It is not compatible with push-fit systems.
  • Application: Ideal for use in domestic and commercial soil, waste, and vent systems.
  • Color Options: Available in White (MU311W), Black (MU311B), and Solvent Grey (MU311SG) to match different systems and preferences.
