Norgren 5VS-221-000 Rotowink Pressure Indicator 1/8in Nptf

Product Description

The NORGREN 5VS-221-000 is a Rotowink pressure indicator designed for visual pressure status monitoring in pneumatic and fluid systems. The indicator uses a color-coded visual flag to signal system state: green when unactuated and red when actuated, giving technicians an immediate at-a-glance pressure status without the need for gauges or additional instrumentation. It accepts a 1/8 inch male NPTF connection at the bottom port and is rated for pressures between 15 and 150 psi with a maximum temperature of 150 degrees F. Licensed HVAC technicians, pipefitters, and pneumatic system specialists typically install this indicator as part of pressure monitoring or status-indication assemblies.

The 5VS-221-000 suits residential and commercial pneumatic control systems, compressed air lines, and fluid distribution circuits where quick visual confirmation of pressurization or de-pressurization is required. The bottom-port configuration allows straightforward inline or manifold mounting. It is suited for applications where panel or assembly space is limited and a compact, self-contained visual indicator is preferred over a dial-type gauge.

Key Features

• Color-coded visual indication: green when unactuated, red when actuated for immediate status recognition
• 1/8 inch male NPTF bottom port for secure, leak-resistant thread engagement
• Operating pressure range: 15 to 150 psi
• Maximum temperature rating of 150 degrees F
• Compact Rotowink design suited for panel-mount or inline assembly installations

Compatibility

Designed as an OEM-style replacement or addition for pneumatic and compressed air systems requiring a 1/8 inch male NPTF bottom-port pressure indicator rated to 150 psi.

Installation Notes

Installation is typically performed by a licensed pipefitter, HVAC technician, or pneumatic systems technician. Before installation, depressurize and isolate the system completely. Apply thread sealant appropriate for the system media to the NPTF threads, and tighten to hand-tight plus a standard turn per fitting manufacturer practice without over-torquing the indicator body. Verify system pressure is within the 15 to 150 psi operating range before returning the system to service.
