Industrial MS24540-2 Oil Pressure Gauge Military Spec

The MS24540-2 is a 0–120 psi, 24 VDC analog oil‑pressure gauge engineered for severe‑duty military electrical systems. With a 2-1/16 in (52 mm) dial, it provides direct engine oil pressure indication on the dashboard using electrical resistance from a compatible 0–120 PSI oil pressure sender. Identified by NSN 6620-00-115-9042 and carrying the MPN MS24540-2, this indicator is designed for installation on the dashboard instrument panel of Humvee M998, M35, M809, M939, M44, and M54 series vehicles, as well as other 24‑V military platforms. The gauge uses a military rubber shell connector system and is intended for repair, restoration, or replacement of failed oil pressure indicators in tactical vehicles, generators, and support equipment where monitoring lubrication pressure is critical. Common replacements include OEM MS24540-2 assemblies or compatible 24‑V oil pressure indicators such as the Stewart-Warner 120 PSI military gauge, with alternate part numbers 8674895, 12338471, 5568665, and 1001204 noted in catalog data.
