The Multiquip EM16478 Hydraulic Oil Sight Gauge is a genuine OEM component designed for ST and LS series concrete pumps, including the ST-45HRM, ST-70, LS-40, LS40TD, LS50TD, and LS60TD. As a factory-authorized replacement, EM16478 is manufactured to the same specifications as the original, ensuring an accurate and consistent hydraulic oil reading every time. Keeping hydraulic oil levels properly monitored is critical on these pumps, and this sight gauge delivers the visibility operators depend on to catch issues before they become failures. DHS Equipment stocks this genuine Multiquip part ready to ship.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specifications for the EM16478, ensuring correct fluid visibility, seal integrity, and mounting dimensions on hydraulic oil reservoir applications.
- Direct-Mount Replacement — Mounts directly into the existing reservoir port on compatible ST and LS series concrete pump hydraulic systems with no rework to surrounding hardware.
- Broad ST and LS Series Compatibility — Confirmed fit for ST-45HRM, ST-70, LS-40, LS40TD, LS50TD, and LS60TD concrete pumps, covering both swing-tube and hydraulic-driven pump configurations.
- Clear Level Visibility — Provides a quick visual reference of hydraulic oil level, allowing operators to identify low-fluid conditions before pump performance is compromised or internal hydraulic components are damaged.
- Hydraulic System Protection — A failed or cracked sight gauge can mask dangerously low oil levels, leading to hydraulic pump cavitation or seizure; replacing it promptly keeps the system operating with full situational awareness.
The hydraulic oil sight gauge gives operators a direct visual indication of fluid level inside the hydraulic reservoir. On concrete pumps like the ST and LS series, maintaining correct hydraulic oil level is essential — the hydraulic system controls pumping output, valve actuation, and overall machine function. A sight gauge that is cracked, clouded, or leaking makes it impossible to confirm oil level at a glance, which can allow the reservoir to run low undetected, causing accelerated wear or sudden failure of hydraulic components.
