• Use a seal tape or a seal material to stop leakage from piping.
Apply a seal tape or seal material to the screw threads leaving two or more threads at the pipe end
uncovered or uncoated. If the pipe end is fully covered or coated, a shred of tape or residue of seal
material may enter inside of the pipes or device and cause a failure.
When using a seal tape, wind it around the screw threads in the direction opposite from the screw threads
and press it down with your fingers to attach it firmly.
When using a liquid seal material, be careful not to apply it to resin parts. It damages resin parts and
causes a failure or malfunction. Also, do not apply it to internal threads.
