Natural Rubber Inflatable Pipe Bung

Made from durable natural rubber, this inflatable bung is designed for reliable sealing in pipes with internal diameters ranging from 50 mm to 600 mm. It accommodates standard pipe sizes including 50, 100, 150, 200, 225, 250 and up to 600 mm ID. The bung inflates to a maximum working pressure of 100 kPa and is supplied as a single unit. Its black colour and smooth surface ensure compatibility with common drainage and testing applications. For optimal performance, the pipe interior must be clean, flat and free of burrs or gaps — especially avoiding use at pipe joints where seal integrity may be compromised.
