Description

Plumboss Double Seal Test Plug 8in (200mm)

Stable sealing for uneven pipe surfaces

The Plumboss Double Seal Test Plug is designed for pipeline testing where uneven pipe surfaces or longer duration sealing requires extra stability. The double seal design helps centralise the plug within the pipe, creating a secure and consistent seal during testing and maintenance operations.

Double seal test plugs are commonly used where pipe bores are irregular or where a more stable seal is required for extended testing periods. The dual sealing system improves stability and helps the plug resist movement under pressure, making it suitable for demanding pipeline test environments.

For uneven wall surfaces, ensures squarer seal. 4in - 15in
