About Test Plugs more than 350mm

Test plugs greater than 350mm are essential tools in pipe testing, enabling you to safely isolate sections of pipeline during inspection or maintenance works. An inflatable test plug is ideal for large diameter applications, providing a secure seal without damaging the pipe wall.

These are commonly used in civil construction, plumbing and infrastructure projects, and are designed for both air and water pressure testing. These plugs can help detect leaks, block off pipes or create a safe testing environment for new installations. Thanks to their flexible inflation design, they are easy to insert and remove, even in confined areas.

When working with sewer lines or water mains, a high-quality plumbing test plug can improve accuracy and safety. With test plug hire from Coates, you’ll find the right fit to suit a variety of pipe sizes and work sites.
