Brett Martin 300mmx150mm 90 Degree Twinwall Branch

• Format: Triple‐socket branch fitting (three connections) in a twinwall drainage system.
• Nominal sizes: Main run diameter = 300 mm, branch diameter = 150 mm.
• Branch angle: 90° (right angle).
• Material: High‐density polyethylene (HDPE) Twinwall – corrugated outer wall, smooth bore inner. This is standard for the Brett Martin Twinwall pipe/fitting system.
• Certification: Part of the Twinwall multi‐fittings range that is covered by the BBA certificate (10/H168) for the 150mm-300mm diameter range.

• The Twinwall 300mmx150mmx90° branch is supplied with the seals.

• Reducing branch: With a 300 mm main run and 150 mm branch, it allows the designer or installer to connect a smaller branch pipe off a larger main trunk – useful when flows reduce or a service branch is required.

• Right‐angle (90°) branch: The branch takes off at a true 90° angle, which is often needed in network layouts where a perpendicular connection is required or space constraints dictate such orientation.

• Triple‐socket design: Provides sockets for the main inlet, main outlet (continuing 300 mm) and the 150 mm branch socket – simplifying installation compared to bespoke fabricated junctions.

• Twinwall HDPE construction: Advantages include lower weight (easier handling on‐site than concrete equivalents), chemical resistance, durability underground, smooth bore for hydraulic efficiency.

• Compatibility: Fits the Brett Martin Twinwall system (and compatible BBA approved Twinwall pipes) in the 150mm-300mm range, which helps with spec consistency and stock control.

• Watertight potential: When correctly installed with suitable sealing rings (one per socket size) and joint lubricant as specified, the system may be suitable for sealed carrier drainage applications. (Manufacturer’s instructions emphasise correct sealing).
