Pressure Pipe Rubber Inflatable Bung / Drain Stop Block (200mm) A pressure inflatable rubber air bag designed to temporarily seal and block pipes, drains and conduits in home, garden and light commercial settings. This listing is for the 200mm model; the product is also available in 20, 25, 50, 75, 100, 150 and 250mm sizes to match a wide range of internal pipe diameters. Key benefits Reliable temporary seal: Inflatable design conforms to the pipe bore to create a tight, reliable block for testing, maintenance and isolation. pressure capable: Designed for use where a stronger seal is needed compared with rigid plugs and mechanical stoppers. Reusable and economical: Inflates and deflates for repeated use, reducing the need for singleuse or permanent plugs. Versatile application: Suitable for plumbing pressure tests, drain and sewer work, irrigation maintenance and many home and garden tasks. Main features and attributes Functionality: Inflatable bung/air bag forms a gastight seal inside the pipe to stop flow or hold pressure during inspection, or cleaning. Compatibility: Available in nominal internal diameters of 20, 25, 50, 75, 100, 150, 200 and 250mm. Choose the size that matches the pipe internal diameter for proper sealing. Size (this listing): 200mm model—intended for pipes with approximately 200mm internal diameter. Material: Made from flexible rubber to conform to pipe walls and provide a durable sealing surface. Performance: pressure inflatable design delivers a stronger hold than passive plugs, ideal for temporary blockage and pressure testing tasks. Typical use cases Plumbing and pressure testing: Insert the inflatable bung into a drain or pipe section and inflate to seal the line for pressure testing, leak identification or commissioning. Maintenance and isolation: Temporarily block a section of pipe to stop flow while repairing downstream fittings, replacing sections, or performing inspection work. Garden and irrigation work: Use on irrigation mains, garden drainage lines or pond outlets to isolate and clean lines, control flow during maintenance, or prevent backflow while servicing equipment. How to use (concise) 1. Select the size that matches the pipe internal diameter (200mm for this model). 2. Insert the deflated air bag into the pipe and position it where a seal is required. 3. Inflate using an appropriate air source until the rubber expands to contact the pipe walls and blocks flow. 4. Complete the required work or test, then deflate and remove the bung for storage. What to consider Match the bung size to the internal diameter of the pipe for effective sealing. Use appropriate inflation control to prevent overinflation. Intended for temporary blocking, pressure testing and maintenance tasks in home, garden and similar applications. This pressure inflatable rubber bung (200mm) offers a practical, reusable solution for sealing and isolating pipes during testing and maintenance, with multiple sizes available to fit common pipe diameters.
