Brett Martin 300mmx225mm 90 Degree Twinwall Branch

Key Features & Benefits

• Precision Reduced Branch Connection: Seamlessly connects a 225mm twinwall lateral pipe into a main 300mm twinwall drainage run at a 90° angle.

• High-Density Polyethylene (HDPE) Construction: Impact, chemical, and abrasion-resistant structure built to withstand heavy soil loads and aggressive ground chemicals.

• Corrugated Outer & Smooth Bore: Combines high structural strength with a smooth internal lining to maximize hydraulic flow and reduce sediment buildup.

• Fully Compliant Drainage Fitting: Manufactured to meet stringent UK highway, civil engineering, and agricultural land drainage requirements.

• Quick, Secure Jointing: Designed for rapid pushed-fit connection with compatible 300mm and 225mm twinwall pipe systems using standard sealing rings.

The Brett Martin 300mm x 225mm 90 Degree Twinwall Branch (Code: 3TT290) is a heavy-duty civil engineering drainage fitting engineered to introduce a 225mm secondary junction into a primary 300mm twinwall pipe run. Ideal for highway drainage, agricultural land management, commercial site developments, and attenuation schemes, this branch fitting ensures efficient fluid transfer and reliable structural integrity underground.

Manufactured from high-density polyethylene (HDPE), the fitting utilizes a dual-wall construction: a corrugated exterior ring design for superior ring stiffness against deep backfill loads, paired with a smooth internal bore that ensures unhindered water flow and minimizes the risk of blockages.
