CAUTION
Graco recommends using PTFE tape on hose threads 
prior to installing the Matrix meter. PTFE tape should 
be after the leading thread and clockwise (same direc-
tion as meter installs on hose fitting). Caution should 
be taken not to get tape into the meter during installa-
tion as this can cause the meter to malfunction. 
Should the tape be the cause of the malfunction, 
Graco warranty will be denied.
