Brett Martin 87.5° Long Radius Plain End Channel Bend

Key Features & Benefits

• Swept Long Radius Curve: Features a smooth 87.5° long-radius bend engineered to reduce turbulence, minimize blockage risks, and promote optimal hydraulic flow in underground drainage networks.

• Open Channel Design: Specifically designed for use inside masonry or precast concrete inspection chambers (manholes) to seamlessly redirect waste flow.

• Plain End Connections: Features smooth spigot plain ends that insert cleanly into standard chamber channels, socketed fittings, or rubber seal couplings.

• Heavy-Duty Underground PVCu: Manufactured from tough, durable PVCu resistant to chemical attack, ground movement, and effluent corrosion.

• Multiple Diameter Options: Available in standard 110mm (B2531) and 160mm (B3331) sizes to suit domestic and commercial main drainage lines.

The Brett Martin 87.5° Long Radius Plain End Channel Bend is a precision-moulded underground drainage fitting designed for smooth directional changes inside access chambers and manholes. Available in two industry-standard sizes — 110mm (Code: B2531) and 160mm (Code: B3331) — this fitting ensures efficient waste management across residential and commercial developments.

Unlike sharp tight bends, the long radius design forms a gradual 87.5° curve that maximizes fluid velocity while substantially lowering the risk of solids settling or creating blockages within the chamber layout. The open-channel profile allows for easy inspection, testing, and rodding access from ground level.
