PVC Socket Plug SN8

  Datasheet (PDF)

The PVC socket plug SN8 SDR 34 provides a dependable, airtight, and watertight termination for unpressurized buried sewage and drainage pipe systems. Engineered for direct insertion into standard socketed pipe ends and fittings, the plug utilizes an elastomeric EPDM rubber sealing ring interface to maintain leak-tight joint integrity under demanding subterranean operating conditions. Designed with an SN8 ring stiffness rating of 8 kN/m² in SDR 34 geometry, the fitting exhibits robust structural stability capable of withstanding substantial static earth backfill loads alongside dynamic stresses generated by heavy vehicular traffic in external networks. Manufactured from unplasticized polyvinyl chloride (PVC-U), the component ensures superior chemical resistance to aggressive domestic and industrial effluents across a pH range of 2 to 12, successfully resisting biological agents, caustics, and acidic substances present in wastewater and ground soils. The system accommodates effluent service temperatures up to 40 degrees Celsius under continuous gravity flow, with short-term thermal surges acceptable up to 60 degrees Celsius. Its precise spigot profile facilitates efficient seating into sockets, preventing accidental displacement and securing pipeline networks during phased construction, testing, or permanent branch termination across utility, municipal, and industrial infrastructure projects.
