PP Elbow 87°

  Datasheet (PDF)

The PP 87 degrees elbow is an injection-moulded polypropylene fitting designed for directional changes in gravity-fed soil, waste discharge, and internal ventilation piping networks within residential, commercial, and industrial buildings. Engineered for rapid, purely mechanical push-fit installation, the fitting features a precision-calibrated socket housing a factory-fitted elastomeric EPDM lip seal, creating an immediate, watertight barrier that accommodates axial pipe movements and structural building vibrations without requiring solvent adhesives or hot-welding techniques. Polypropylene construction ensures comprehensive chemical resistance across a fluid operating range of pH 2 to pH 12, providing dependable conveyance of acidic and caustic aqueous solutions, dissolved mineral salts, and aggressive detergent solutions discharged by industrial laundries and dishwashers. The fitting performs continuously under standard wastewater discharge regimes up to 60 degrees Celsius and reliably handles short-term thermal surges up to 95 degrees Celsius, while preserving high impact resistance and ductility in cold working environments down to minus 15 degrees Celsius. Manufactured with an exceptionally smooth interior bore defined by a Manning roughness coefficient of 0.01, this component prevents limescale sedimentation, eliminates particulate build-up, and delivers superior resistance against abrasive solids. Manufactured in strict conformity with SR EN 1451-1 standards, the 87 degrees configuration provides streamlined flow transition in gravity drainage stacks and branch connections, ensuring trouble-free hydraulic performance and an operational service life of at least 50 years.
