CLEANING PROCEDURE







1. Fabricate a cleaning tool from a 1/8 inch diameter brazing rod.
2. Cut an abrasive pad from maroon colored 3M Scotch Brite(R) with the dimensions corresponding to the coupling size.

3/8 inch 25 x 50 mm (1 x 2 inch)
1/2 inch 25 x 50 mm (1 x 2 inch)
5/8 inch 25 x 76 mm (1 x 3 inch)

3. Assemble the pad to the tool.

5. Roll the pad on the tool and install it in a variable speed drill motor.







6. Polish for 1 minute at moderate speed (less than 1500 rpm) or until the surface is clean and free of scratches or debris.

CAUTION: Maintain low speed drill rotation when inserting or removing the cleaning tool to prevent axial scratches which may cause future leaks.
