Brett Martin 300mm 90 Degree Bend Twinwall

• Nominal diameter: 300 mm Twinwall pipe system.

• Fitting type: 90° bend (double‐socket) — designed to change direction by 90° in a Twinwall drainage run.

• Socket type: Double socket (inlet + outlet) – this is typical for a bend rather than a branch.

• Material: High‐density polyethylene (HDPE) Twinwall construction (corrugated outer wall, smooth bore inner wall) — typical for surface water Twinwall drainage systems.

• Certification / range: The Brett Martin Twinwall brochure lists the “300mm 90° double socket bend” code 3TB90 in its nominal size 300 mm list.

• The Twinwall 300mm 90° Double Socket Bend is supplied with Seals. 

• Sharp 90° directional change: Useful when you need to redirect a Twinwall drainage run with a right angle turn (e.g., around corners of trenches, underfoot traffic areas, or where space is constrained).

• Large diameter (300 mm): Suitable for high capacity surface water drainage runs, trunk mains or where large flow volumes are expected.

• Twinwall design: The smooth inner bore supports efficient flow, the corrugated outer wall provides structural strength and supports installation in trench/backfill environments. This design is significantly lighter than concrete alternatives and easier to handle.

• Compatibility: Fits the 300mm Twinwall pipe system of the brand (and likely approved compatible systems) — simplifies system specification and installation.

• Watertight potential: When properly installed with sealing rings and joint lubrication, Twinwall systems can provide sealed carrier drainage. Many of the listings for 300mm Twinwall 90° bends note sealing rings required.
