Heavy-duty sealing for pipe testing
The Plumboss Pressed Steel Test Plug is designed for sealing pipelines during pressure testing, pipe stopping and purging applications. Manufactured from durable pressed steel, these plugs provide a strong and reliable mechanical seal inside the pipe.
Pressed steel test plugs are ideal for higher-pressure applications where a stronger and more durable solution is required. Commonly used as pipe stops, for pressure testing and pipe purging, they provide a dependable temporary seal in plumbing, civil, drainage and industrial pipeline systems.
