Mechanical Plugs

Cherne mechanical plugs for pipes are robust sealing devices that use expanding mechanisms or threaded compression systems to create watertight seals in water and wastewater pipelines during maintenance, testing, or emergency repair operations. These durable plugs enable utilities to isolate specific pipeline sections for pressure testing, flow diversion, or system modifications without requiring excavation or permanent alterations, providing reliable temporary blocking solutions for both pressurized water mains and gravity-fed sewer systems.
