Colin Taylor, Conex Bänninger Technical Engineer, outlines the steps to installing the user-friendly Conex Bänninger >B< Press, an innovative press system which is quick and simple to install providing a secure leak free fitting.

To ensure that you never miss an un-pressed joint again, Conex Bänninger >B< Press developed a unique pressing indicator. A specially designed O-Ring that has a reduced section in two positions causing leaks at low pressures when not pressed (from 0.1 to 5.0 bar) and available in three colours Black-Water, Yellow-Gas and Green-Solar. Without going to full test pressure, when tested they will leak profusely alerting you to un-pressed joints. The leading edge design ensures the chances of damage to the O-Rings are reduced during assembly.

Steps 1: Ensure the tube and fittings sizes are compatible.

Steps 2:  Cut the tube and square, and ensure it retains its shape.

Steps 3:  Deburr the inside, and outside of the tube.

Steps 4:  Mark the tube to the correct tube stop depth as a visual aid.

Steps 5:  Check the o-rings are present in the fitting.

Steps 6:  Insert the tube into the fitting, passed the o-ring, until it meets the tube stop and the mark on the tube is still visible.

Steps 7:  Insert the >B< Press profile Jaw with the correct profile and size into the >B< Press Tool. Open the press jaw, and align with the O-ring bead, allow the jaw to close.

Steps 8:  Operate the press machine to press the fitting. The machine will stop at the end of its pressing cycle.

Steps 9: Open the jaw and remove from the fitting. Make sure all joints have been pressed. If the joint(s) is (are) not pressed, when pressure tested they will leak profusely.
