Goulds Centripro AS4 Standard Pressure Switch 30 / 50 PSI

The Goulds AS4 pressure switch comes preset for 30 / 50 psi. This means the pump comes on when the pressure falls to 30 psi, and shuts off when the pressure reaches 50 psi. The switch is also capable of being adjusted a few psi in each direction to best suit your needs or application. They feature a standard 1/4" female NPT pressure connection. These AS4 pressure switches are suitable for most 115v and 220v water pumps, including jet pumps and submersible pumps.
