Sewage Blocking Plugs (Pneumatic Testing Rubber Air Bags)

Sewage blocking plugs, also known as pneumatic testing rubber air bags, are used to temporarily seal sewage pipes during maintenance or testing. Made from durable rubber, they expand when inflated to block flow and allow pressure or leak tests. Ideal for isolating sections of drainage or sewer lines, these plugs ensure safety, efficiency, and compliance during repair, inspection, or installation work.
