40mm Back Entry Glycerine Filled Pressure Gauge

40mm Back Entry Glycerine Filled Pressure Gauge

Designed for pumps, compressors, hydraulic equipment and general machinery, this 40 mm gauge uses glycerine filling to steady the pointer in unsettled service. Its compact 40 mm dial is well suited to small machines, control panels and installations where space around the connection is limited. The liquid filling dampens movement caused by vibration and pressure fluctuations, helping the operator obtain a steadier reading at the equipment.

A rear-facing connection allows the gauge to sit neatly against compatible panels, fascias and equipment housings. The layout is particularly useful on machine fascias and hydraulic panels exposed to regular movement. Model selection should reflect the working pressure, connection, medium, temperature and the amount of vibration present at the measuring point.

Applications

Hydraulic Power Pack Panels

On compact hydraulic power pack panels, 40mm back entry format provides local pressure visibility while Glycerine filling helps damp movement from vibration or pulsation.

OEM Machine Builds

Machine builders can integrate this gauge into enclosures or control panels where a small industrial pressure gauge glycerine filled design is required for front-facing indication.

Pump and Compressor Skids

For pump or compressor skid instrumentation, the stainless steel case supports industrial environments and the brass wetted parts should be matched to compatible media.

Maintenance Replacement Gauges

Maintenance teams may specify this back entry gauge when replacing compact panel-mounted pressure instruments with the same connection style and material requirements.

Features

Dial

The 40mm dial gives compact local pressure indication where panel space or machine envelope is limited. It is well suited to close-mounted readings on smaller assemblies.

Configuration

The back entry connection supports rear mounting into panels, machines or instrument housings. This layout helps keep the gauge face aligned for front viewing.

Construction

A 304 stainless steel case provides durable external protection, while brass wetted parts suit compatible pressure media. Material compatibility should be checked against the process fluid or gas.

Accuracy

Specified accuracy is 2.5%, supporting consistent local pressure indication for routine industrial monitoring. Confirm the accuracy requirement against the measurement duty.
