Key Features & Benefits

• Precision Angle Alignment: Creates a smooth 15° direction change in unpressurised surface water and highway drainage pipework.

• High Strength & Low Weight: Manufactured from HDPE twinwall construction, offering exceptional crush resistance and stiffness without the structural weight of concrete or clay.

• Multiple Diameter Options: Available to fit 150mm (1TB15), 225mm (2TB15), and 300mm (3TB15) twinwall drainage systems.

• Corrosion & Chemical Resistant: Highly resilient against aggressive soils, runoff chemicals, and environmental weathering for a long service life.

• Fast Push-Fit Installation: Designed for fast, secure jointing on site using standard twinwall seals to maintain seal integrity under subterranean movement.

The Brett Martin 15° Twinwall Drainage Bend is an essential fitting engineered for altering pipe runs in non-pressure surface water, agricultural, and civil engineering drainage applications. Designed to work seamlessly with Brett Martin and compatible twinwall pipe systems, this 15° bend allows installers to make gradual alignment changes around site obstacles, property boundaries, and shifting trench layouts.

Constructed from durable high-density polyethylene (HDPE), the twinwall design features a smooth internal bore for optimal fluid flow rates and a corrugated outer wall that provides high ring stiffness under soil load. Unlike traditional heavy concrete alternatives, these lightweight fittings significantly reduce handling times on site while remaining fully resistant to corrosion, rot, and impact damage.
