Distribution fittings supplied, sewer fittings quoted per project
For municipal contractors and wholesalers, HengHaoSen supplies PVC Schedule 40/80 pressure fittings and plastic valves for distribution networks, shipped by container against US-standard catalogs; SDR35 sewer fittings are quoted against project spec lists. Full export documentation with staged delivery supported.
PVC Schedule 40 fittings are injection moulded from unplasticised PVC to the Schedule 40 wall series: pressure-rated at ambient temperature, resistant to acids and alkalis, non-conductive, and joined by solvent weld in a single operation.

Schedule 80 shares the PVC-U material of Schedule 40 but carries one wall class more at the same nominal size, so it holds higher working pressure; the dark grey body marks the difference on site. It is the usual choice for commercial and industrial water lines, pump rooms and water treatment skids.
