AIR PLUG 4/ 100mm (91-142mm)

Air plugs for pipeline testing are filled through Schrader valves. Filling must be done slowly, for example with a hand pump, to achieve a tight final result. Too rapid filling may burst the plug or cause bulges. Excessive filling does not increase pressure resistance. All plugs are equipped with a 1.3 m filling hose. Back pressure resistance is 0.6 bar.
