This unit is listed as an alternate to Part Number 877730, making it a potential replacement option for applicable aircraft and system installations where the alternate part is approved. The mechanical design provides a simple method of checking fluid level during normal aircraft operation, preflight inspection, and scheduled maintenance without relying on an external electrical indication system.

The assembly is suitable for replacement of an existing gauge where the original component is worn, damaged, inaccurate, or otherwise unserviceable. Its compact construction allows it to be integrated into the applicable fluid reservoir or tank assembly while providing the operator with a direct indication of the fluid level.

For aircraft maintenance applications, verify the applicable aircraft model, system configuration, installation dimensions, connection requirements, and approved interchangeability information before ordering or installation. Part number interchangeability should be confirmed using the current aircraft maintenance manual, illustrated parts catalog, or other applicable approved documentation.
