Safe-T-Seal 8" Mechanical Test Plug

The Safe-T-Seal TTMP-8WF is a rubber mechanical test plug designed to seal pipe interiors during pressure testing. It fits pipe inside diameters from 0.38 in up to 8 in and includes a water fill port with hose for hydrostatic testing. The unit has an overall height of 10.5 in and uses galvanised steel plates and handle.

Suits pressure testing up to 40 ft head

This plug suits installers performing hydrostatic tests up to 40 ft of head or pneumatic tests up to 20 psig back pressure. It is not for pipelines exceeding the 8 in maximum inside diameter or for applications requiring a padlock shackle, as none is applicable.

8 in maximum pipe inside diameter

The decisive specification is the 8 in maximum pipe inside diameter, which sets the upper limit for the seal. Pipes larger than this require a different plug size to achieve a secure test seal.

  • Handles 20 psig air back pressure for reliable testing

Questions about this item

What pipe inside diameter range will the 8" mechanical test plug seal?

The plug seals pipe inside diameters from .38 in up to 8 in.

Will the 1/2 in NPS female bypass connection thread onto my existing galvanised fittings?

Yes, the bypass uses a standard 1/2 in NPS female thread that mates with matching male galvanised pipe threads.

How can I verify the plug is holding after I tighten the handle?

Pressurise the line to the rated 20 psig air or 40 ft of water head; no pressure drop confirms the seal.
