Compact Stainless Steel Pressure Indication for Rear-Mounted Installations

The 40mm Back Entry All Stainless Steel Pressure Gauge from GNW Instrumentation provides local pressure indication in a compact format for industrial equipment, OEM assemblies and maintenance replacement work. Its 40mm dial is appropriate where available mounting space is limited, while the rear connection allows the gauge to sit neatly through a panel, housing or equipment face.

This all stainless steel pressure gauge uses a 304 stainless steel case with 316 stainless steel wetted parts, making it relevant for compatible liquids and gases where stainless process contact is preferred over brass or mild steel alternatives. The construction is particularly practical on packaged plant, machinery and stainless process pipework where material compatibility and external corrosion resistance both need consideration.

With a stated accuracy of 2.5%, the gauge gives a clear basis for selection against the tolerance required at the measuring point. It is best specified where compact visual indication is needed rather than high-precision measurement, and where the back entry configuration matches the existing installation or panel layout.

Specification Considerations

Before ordering, check the process media, connection arrangement and available mounting depth against the installation. For replacement work, confirming the existing dial size, rear connection style and required accuracy helps ensure the instrument fits correctly without unnecessary modification.

• 40mm dial for compact machine or panel-mounted pressure indication.
• Back entry connection for rear mounting through equipment faces or enclosures.
• 304 stainless steel case with 316 stainless steel wetted parts.
• 2.5% stated accuracy for general industrial pressure indication.
