Plumboss Double Seal Test Plug 10in (250mm) | 10DS

Plumboss Double Seal Test Plug 10in (250mm) 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 PRODUCT CODE DESCRIPTION MIN/MAX - (mm) BSP OUTLET SIZE 4DS TEST PLUG DOUBLE SEAL 4in (100mm) 94 - 110 ½in 6DS TEST PLUG DOUBLE SEAL 6in (150mm) 146 - 163 ½in 8DS TEST PLUG DOUBLE SEAL 8in (200mm) 191 - 211 1in 9DS TEST PLUG DOUBLE SEAL 9in (225mm) 216 - 235 1in 10DS TEST PLUG DOUBLE SEAL 10in (250mm) 244 - 260 1in 12DS TEST PLUG DOUBLE SEAL 12in (300mm) 296 - 314 1in 15DS TEST PLUG DOUBLE SEAL 15in (375mm) 365 - 400 1in Operating Pressure Sizes This is a guide to the maximum back pressure for the different types and sizes of test plugs.

Plumboss Plug Safe Right Angle Test Plug Adaptor | PSBW-6

Plumboss Plug Safe Right Angle Test Plug Adaptor External tightening test plug system The Plumboss Plug Safe system is an Australian-made solution designed to prevent losing test plugs down inspection openings while allowing tightening from outside the pipe. The zinc‑plated steel adaptor features a 200mm handle so the plug can be installed and tightened externally, keeping hands clear of the pipe and reducing the risk of cuts, abrasions and lost plugs. Using a screw and wedge mechanism, the Plug Safe system grips significantly tighter than standard hand tightening. Ideal for pipe stopping, pressure testing and maintenance work where inspection openings limit access inside the pipe.
