Nordyne 632443R Pressure Switch utilizing standard spade terminals and

utilizing standard spade terminals and a flush-mount flange

Automatic Reset Functionality: Eliminates manual intervention by restoring circuit continuity once the plenum temperature stabilizes

Most Reznor burner manifolds require a standard deep-well socket or nut driver for removal and installation of the orifice plug

effectively capturing large particulate matter and protecting sensitive internal components like coils and blower motors from debris buildup

It converts the linear motion of the pneumatic actuator into the specific stroke required to modulate the valve stem accurately
