Description

The MDPE Compression Reducing Tee is designed to create a reliable junction between two MDPE pipes of the same diameter and a third, smaller MDPE branch pipe at a 90° angle. This fitting is ideal for systems requiring a reduction in branch size without compromising joint strength or water-tightness. Suitable for both above-ground and buried applications, it is widely used in water distribution, irrigation, and infrastructure pipe networks. For maximum sealing integrity, the use of pipe liners (stiffeners) is strongly recommended.

Key Features & Benefits

  • Branch Reduction Capability: Facilitates a secure and compact branch connection to a smaller MDPE pipe.
  • Secure Compression Joint: Push-fit ends ensure easy assembly and robust performance without disassembly.
  • UV-Stabilised and Corrosion-Resistant: Ideal for both buried and exposed installations, offering long-term environmental resistance.
  • High Seal Integrity: Sealing system includes nitrile rubber gaskets and acetal grip rings for leak-free operation.
  • Quick and Tool-Free Installation: Designed for convenience and speed—no welding, adhesives, or special tools required.
  • Optimised with Pipe Liners: Stiffeners are advised to maintain pipe shape and reinforce the seal, especially under pressure or thermal stress.
