PP End Cap

  Datasheet (PDF)

PP end caps provide a secure, watertight terminal closure for pipeline ends and unused branch sockets across gravity soil, waste discharge, and internal building ventilation systems. Manufactured from high-grade polypropylene in standard neutral grey, the fitting is engineered for closing off spigot ends or socket connections during hydraulic pressure testing, staged facility renovations, or permanent line termination in multi-storey residential, commercial, and industrial drainage installations. The push-fit connection mechanism functions seamlessly with standard socket geometries, engaging the factory-fitted EPDM elastomeric lip seal to establish a hermetic, pressure-tight barrier against wastewater leakage and sewage odor escape without requiring adhesives, solvent cements, or hot-air welding. The polypropylene body delivers robust operational reliability across severe thermal environments, maintaining structural integrity under standard operating conditions of 60 degrees Celsius, enduring intermittent high-temperature hot water discharges up to 95 degrees Celsius, and resisting brittle failure at low temperatures down to minus 15 degrees Celsius. Due to its extensive chemical resistance, the cap reliably withstands corrosive media, domestic laundry and dishwashing detergents, cleaning formulations, organic compounds, and industrial solutions covering a wide operating range from pH 2 to pH 12. The ultra-smooth inner surface, characterized by a Manning roughness coefficient of 0.01, inhibits limescale deposition, bacterial colonization, and solid sedimentation while resisting abrasive degradation caused by suspended grit. With an integrated EPDM seal capable of absorbing linear pipe expansion and structural building vibrations, the fitting ensures enduring joint reliability and a continuous service life of at least 50 years.
