About Test Plugs less than 350mm

This test plug size is designed to temporarily seal off pipe sections so you can conduct leak checks, pressure testing or isolation without full disassembly. Common across civil works, plumbing maintenance and new pipe installations, these plugs come in multiple configurations.

Coates offers a versatile range of test plugs for pipe testing jobs up to 350mm in diameter.

An inflatable test plug is compact, easy to insert and highly adaptable to irregular pipe walls. Mechanical variants offer a secure hold and quick installation. Each plumbing test plug in this range is suitable for gravity-fed systems or low-pressure pipelines. Their durable build and effective sealing help minimise fluid loss and speed up pipeline work.

From basic plumbing to complex civil pipe networks, our test plug hire supports a wide range of applications while helping maintain job site safety and efficiency.
