Probe only - must be wired to an exisiting detection module (alarm). Water sensor probes can be installed in diesel fuel filter bowls to alert you when water has accumulated in the bowl and it is time to drain.
Includes a separate 2-wire connector which clips onto the probe - so no wire is left should you need to disconnect the wires to the detection module. Must be used with a detection module (buzzer, etc.) - such as RAC RK 20725 or 20726.
Since the Water Detection Module Kits all come with the one-piece RK 21069 probe, order this part if you are replacing an exisitng probe, and require the special disconnect feature this probe provides.
1/2"-20 threads on probe
Can be used on 12V or 24V systems
Never wire directly to a voltage source
Do not use with another brand of detection module (voids warranty)
Do not use in gasoline applications - explosion hazard
