Commercial series inflatable pipe plugs are constructed with high-quality natural rubber, NBR, neoprene rubber, or other durable materials, reinforced with nylon layers for enhanced resistance to fuel, petrochemicals, and other caustic chemicals. Each plug comes equipped with rigging hardware, inflation ports, and a pressure relief valve.

These multi-size flow stoppers can accommodate a range of pipe diameters, making them versatile for various applications. Their lightweight design ensures easy installation and quick removal, ideal for commercial and light industrial work. When inflated with air or inert gas, they expand to completely block pipes for maintenance, construction, or other projects.
