• | The brass Universal Mandrel is for use on hose fittings with a smooth bore where the screen installs flush with the end of the fitting.

• | The 11.96 mm (0.471 in) Mandrel is only for the 11.96 mm (0.471 in) screen in hose fittings with an internal hourglass shape where the screen installs at the recessed, reduced diameter point.

3. Install the 11.96 mm (0.471 in) screen in the middle of the reduced diameter point of the fitting.
