Pair of multi test pipe stoppers, each with an expansion range of 300-400mm/12-16”, designed for use in a standard air pipe test of 100mm water over air. These inflatable pipe stoppers each require 1.5 bar inflation pressure, and are suitable for a maximum back pressure of 0.1 bar.
Multi test stoppers have 2x 1/4" bypass valves, which can be used for proofing, filling smaller pipes, or testing pipes to a standard air test of 100mm water over air. Each stopper can be used as either the blank or test end of the pipe by shutting off or opening the valves. Each stopper is made from high quality rubber, and is fitted with a series 26 coupling.
