Pronal Bypass Stoppers
Ideal for flow control (blanking off and bypassing) or air testing.
Stoppers must be fully inserted into the pipe prior to inflation and must not be used in pipework within open excavations or unrestrained pipework. All pipes must be anchored before pressure testing.
- May be fitted with up to a 2" BSP lever ball valve (and hydrant coupling if required for filling)
- With bracing, smaller sizes can withstand back-pressures up to 1 bar/10m head water
