HIGH PRESSURE PLUGS
Lansas high pressure test plugs are made from a specially formulated, natural ozone-protected rubber impregnated with several layers of nylon cord. The number of layers is determined by pressure resistance required in the field. The bladder portion of the plug is bonded to its metal inner mandrel. The ends of the bladder, when inflated, roll up to the interior of the pipe walls, giving the plug more sealing surface and less stress on the bladder by not having to stretch as far, thus adding to the strength of the plug.

Lansas high pressure test plugs have been field tested to withstand pressures in excess of several hundred PSI. Like other Lansas products, the roll-up plugs can be custom designed to fit specific applications.
