PP Reduced Branch 67°

  Datasheet (PDF)

The TeraPlast PP reduced branch 67 degrees HTEA 110/50mm is an injection-moulded polypropylene fitting designed for non-pressure domestic soil, waste discharge, and interior drainage ventilation systems. Engineered to merge a secondary 50 mm waste line into a main 110 mm vertical stack or horizontal collector at a 67 degrees angle, this component ensures efficient flow directionality with minimal hydraulic turbulence. The fitting is manufactured in compliance with standard SR EN 1451-1 and features precision-formed sockets equipped with factory-fitted elastomeric EPDM rubber gaskets. This push-fit assembly mechanism allows rapid manual jointing without requiring solvent cements, heating tools, or mechanical fasteners, providing a durable, hermetic seal capable of absorbing linear thermal expansion and system vibrations. With overall structural dimensions including a total laying length of 185 mm, a lateral branch center-to-end dimension of 58 mm, a primary socket depth of 50 mm, and a reduced branch socket depth of 40 mm, the unit integrates smoothly into standardized interior wastewater networks. The high-grade polypropylene construction offers remarkable thermal resistance, handling continuous fluid discharges at temperatures up to 60 degrees and short-term thermal peaks of up to 95 degrees, while retaining structural resilience and impact resistance at ambient temperatures down to -15 degrees. In addition, the material delivers wide chemical compatibility across an operating range of pH 2 to pH 12, successfully resisting aggressive laundry detergents, alkaline washing compounds, commercial sanitizers, and acidic solutions. A smooth internal bore, characterized by a low Manning roughness coefficient of 0.01, reduces flow friction, prevents sediment accumulation, and provides high resistance against abrasive particulate wear. Designed for an expected operating lifespan of at least 50 years, this branch provides robust, leak-free connection reliability throughout gravity drainage installations in residential, commercial, and light industrial facilities.
