Milltest Stopper

(Click for larger image)

Milltest stoppers incorporate an inflatable ring with a central membrane, used to test drainage pipes to a standard air test of 0.01 bar. There are a number of sizes available to provide for the standard range of pipe diameters commonly used. Each stopper is only suitable for a specific diameter, but has a tolerance of +/- 10mm to accommodate slight variations in the manufactured pipes.

Lightweight when collapsed they can easily be passed through a restricted manhole opening. Inflation is via a hand pump or compressor adaptor fitted with a pressure regulator that prevents stopper damage from over inflation.

Note: All stoppers must be braced and all pipes must be anchored before pressure testing. Click here for more details.
