Flexcon Gray Challenger 20 Gallon Pressure Tank
All of Flexcon tanks are constructed with a stainless steel water connection that is welded to the tank wall. This weld provides the strongest water connection in the industry. These tanks are subjected to helium and pressure testing to ensure the structural integrity. Flexcon's patented controlled action, double diaphragm assembly completely contains drawdown water. This design prevents our diaphragm from chafing against the tank wall and surrounds the diaphragm in a pre-pressurized atmosphere.
