A low pressure, low cost ported test plug. Nominal pipe sizes from 2” to 12” (DN 40 to DN 600). Operating pressures to 10 psi (0.7 Bar), depending on plug size.

These plugs come with a hollow stem which can be used as a fill or drain pipe. Turning the wing nut expands the rubber ring tightly against the inside of the pipe. Hand tightening is usually adequate in smaller sizes, but a wrench can be used on larger sizes to give a better seal.
