Specification:

Material: plastic

Fitting: 1/4" compression fitting, easily fitted to 1/4" OD plastic tubing or copper tubing

Electrical: NC, Normally closed, 15" of electrical wires is included

Pressure setting: for water pressure, ON at 45 psi (+ 5); OFF at 20 psi (+ 5) NOTE: the pressure setting is approximately set at this pressure. You can slightly adjust the pressure setting.

Adjustable pressure setting: It is slightly adjustable. The switch's pressure setting can be adjusted by turning the hex-screw on top of the switch. the ON can be adjusted approximately 35 to 55, OFF can be adjusted approximately 15 to 30 psi
