Description
Plumboss Aluminium Test Plug 21 in (525mm)
Heavy duty aluminium plug for large diameter pipe testing
The Plumboss Aluminium Test Plug is designed for sealing large diameter pipelines during pressure testing, maintenance and commissioning. Built for reliability in demanding environments, it delivers a secure mechanical seal for drainage, sewer and civil applications.
Manufactured with a durable aluminium body and centre locking mechanism, this plug expands to create a tight seal inside the pipe. A steel wing nut and brass cap allow controlled tightening and connection for testing. Aluminium test plugs are ideal for leak testing, isolation, sealing, stopping and purging pipework where a strong, corrosion resistant solution is required.
For sealing when testing pipe lines from 1 1/2in up to 48in
