Norgren 5VS-401-000 Rotowink Pressure Indicator 1/8 Nptf

Product Description

The NORGREN 5VS-401-000 is a Rotowink pressure indicator designed for visual pressure monitoring in pneumatic and fluid systems. The indicator features a bottom-entry 1/8 inch female NPTF port and operates across a range of 10 to 125 psi gauge pressure. When system pressure drops below the set threshold, the indicator displays a black unactuated color; when pressure is within the operating range, it switches to a red actuated color, giving technicians an immediate visual status check without requiring gauges or test equipment. Weighing 0.7 pounds, this compact unit suits tight installations in industrial and mechanical systems.

This pressure indicator is suited for pneumatic control panels, compressed air systems, and fluid power applications where a quick-read visual confirmation of line pressure is required. It is typically installed by instrumentation technicians, industrial mechanics, or fluid power specialists in both light industrial and commercial mechanical environments. The bottom-port configuration allows direct inline or manifold mounting where vertical gauge orientation is preferred.

Key Features

• Rotowink visual indicator: black when unactuated, red when actuated for instant status identification
• Operating pressure range of 10 to 125 psi gauge
• 1/8 inch female NPTF bottom port for leak-resistant threaded connection
• Maximum temperature rating of 150 degrees F
• Compact, lightweight design at 0.7 pounds for space-constrained panel installations

Compatibility

Designed as an OEM-style replacement or new-installation pressure indicator for pneumatic and fluid power systems requiring a 1/8 inch female NPTF bottom-port visual indicator rated to 125 psi.

Installation Notes

Installation should be performed by a qualified instrumentation technician or fluid power specialist. Depressurize and isolate the system completely before removing any existing indicator or fitting. Apply appropriate thread sealant compatible with the system fluid to the NPTF threads before installation. Verify the line pressure is within the 10 to 125 psi operating range and does not exceed the 125 psi maximum inlet pressure rating before returning the system to service.
