Pressure Switch, 90/120 PSI #058D6B

Old Part Numbers: 034-0038

OEM part, not an aftermarket part. For 2-3 HP models. Pressure switch for 109B/109BL series and 104B200. Cut in 90 PSI, Cut out 120 PSI.

Replace the pressure switch if the unit doesn't cut on or off at the designated pressure the unit is set for. If the unloader valve is leaking on the side (or underneath of the switch) AFTER the unit shuts off, do not order this part. Order check valve instead.

Note: This pressure switch has a different on/off lever switch on the side, it is now a plastic lever versus the original which had a wire handle lever. This may not fit through the slot in the panel for the lever switch. However, this is the OEM replacement and is the only pressure switch offered by the manufacturer.
