PP Equal Branch 87°

  Datasheet (PDF)

The PP equal branch 87 degrees is an injection-moulded polypropylene drainage fitting engineered for gravity soil, waste discharge, and internal ventilation networks across domestic, commercial, and industrial installations. Designed to connect branch lines into vertical stacks or horizontal collector runs at an 87-degree deflection angle, the fitting optimizes internal flow dynamics by guiding discharge streams smoothly, reducing hydraulic turbulence, and preventing pneumatic siphoning within connected traps. Each connection port incorporates a factory-fitted elastomeric EPDM lip seal seated within an engineered retaining groove, providing immediate watertight integrity and push-fit jointing without the application of solvent cements or welding equipment. This socket configuration doubles as a localized expansion compensator, absorbing structural vibrations, cyclic building movements, and axial thermal variations without seal displacement or joint relaxation. Manufactured in accordance with the SR EN 1451-1 standard, the high-grade polypropylene compound delivers robust chemical resistance across an aggressive operating spectrum from pH 2 to pH 12, reliably withstanding acidic effluent, caustic cleaning agents, industrial salts, and persistent detergent loads from dishwashers and washing machines. Thermally stabilized for demanding building drainage conditions, the component reliably handles continuous wastewater streams up to 60 degrees Celsius and intermittent high-temperature surges reaching up to 95 degrees Celsius, while maintaining structural resilience and impact resistance at ambient temperatures down to -15 degrees Celsius. The non-porous, ultra-smooth interior surface delivers a Manning roughness coefficient of 0.01, effectively suppressing biofilm formation, lime scaling, and abrasive particle wear over an estimated operational lifespan of at least 50 years.
