Duplex pressure gauge
Model : P336 series – Round type
Model : P338 series – Square type

Spec. sheet no. PD03-02
Service intended
P336 and P338 series offer dual air brake system,
differential pressure indication and it can be used for
any other application where two independent pressures
are indicated on a single dial.
