Overview
The Gems 24576 is a complete dual-level liquid switch kit from the Fabri-Level series designed for pipe-plug tank mounting in industrial and process applications. This Gems 24576 liquid switch kit includes all components needed to assemble either a 1- or 2-station level switch unit, eliminating the need to source parts separately. The kit’s robust brass-and-Buna N construction delivers reliable operation across a broad temperature and pressure envelope.
Key Features
- Complete Assembly Kit: Includes 1 tube connector, 1 mounting plug, 2 level stations (switch, tube, float), 2 extension tubes, 1 tube end fitting, and 3 tube unions.
- Dual-Level Configuration: Configurable as 1- or 2-station level switch for independent high and low level control in the same tank.
- Durable Materials: Brass stem material with Buna N float for chemical compatibility and long service life.
- Industrial Pressure Rating: Rated to 150 psi maximum pressure with selectable switch operation.
- Wide Temperature Range: Operating range from -40°F minimum to +230°F maximum temperature.
- Standard NPT Mounting: 2″ MNPT (male NPT) thread size for straightforward tank installation.
