Luminor 300016 UV Sensor Port Plug Kit with O-Ring and Nut

The 300016 is a genuine Luminor sensor-port plug kit. It seals the UV sensor port on a Luminor UV chamber when no UV intensity sensor is installed, for example on BLACKCOMB 5.1 chambers that are ready for an optional sensor upgrade, or whenever a sensor is removed from service. The kit contains the three parts of the plug assembly so the port can be resealed after service. Kit includes Teflon sensor-port plug (Luminor part 310026) O-ring (Luminor part 310120) Retaining nut (Luminor part 390007) When you need it Use the 300016 to replace a worn or damaged plug assembly, to reseal the port after removing a UV sensor, or to replace the O-ring and nut when the port weeps water. If you are adding a UV sensor to a BLACKCOMB 5.1 system instead, the sensor replaces this plug.
