  • Seals pipes up to 3 in with 75 psig air rating

3-Inch Pipe Test Plug

The Safe-T-Seal plug seals 3-inch pipes for pressure testing and temporary blockage. It fits inside diameters from 0.38 in up to 3 in. A long-reach handle made of galvanised steel allows operation from outside the trench. The overall height is 3.5 in.

Sustained Pressure Performance

The plug holds up to 75 psig of air back pressure during extended tests. For water, it withstands 150 ft of head without leaking. Galvanised steel plates maintain their seal under continuous load rather than relaxing after a short burst.

Installation And Common Issues

Insert the plug, then turn the handle to expand the sealing element against the pipe wall. The long handle clears deep installations but requires enough vertical space to rotate fully. No water fill port or hose is included, so a separate fitting is needed for hydrostatic tests.

California Proposition 65 Notice

Questions about this item

Will the galvanised steel handle stay cool and quiet during long pressure tests?

The plug is a passive mechanical tool with no moving parts or power draw, so it produces no noise or heat during extended use.

Do I need a separate water-fill hose or bypass fitting to use the 3-inch test plug?

The specifications state that a water fill port and hose are not included, so you must supply your own hose if water testing is required.

Can this 3.5-inch tall plug seal a 3-inch pipe that already has an older galvanised steel flange?

The plug fits pipes with an inside diameter between 0.38 and 3 inches and uses galvanised steel plates, so it will seal against a matching 3-inch flange.
