Glycerine Filled Pressure Gauges for Industrial & Hydraulic Applications

Glycerine filled pressure gauges are widely used throughout manufacturing, hydraulics, pneumatics, process industries, utilities and mobile equipment applications where vibration or pressure pulsation can make standard dry gauges difficult to read. By filling the gauge case with glycerine, pointer movement is dampened to provide more stable and reliable pressure indication under demanding operating conditions.

This collection includes industrial glycerine filled pressure gauges available in multiple dial sizes, pressure ranges and mounting configurations for use across hydraulic, pneumatic and process systems. Suitable for pumps, compressors, hydraulic power units, industrial machinery and OEM equipment, these gauges are designed to improve readability and reduce internal wear caused by fluctuating operating conditions.

The liquid filling inside the gauge case helps reduce pointer flutter caused by vibration, pulsation and rapid pressure cycling. This allows operators to obtain a clearer and more stable reading during equipment operation, maintenance checks and system monitoring. Glycerine filled gauges are particularly beneficial on mobile plant equipment, compressors and hydraulic systems where dry gauges may experience unstable readings or shortened service life.

Glycerine filled pressure gauges are commonly manufactured with stainless steel or industrial-grade cases to improve durability within industrial environments. Depending on the model, gauges may feature brass wetted parts for standard industrial duties or all stainless steel construction for corrosive or hygienic applications. All stainless steel glycerine filled gauges are widely used within food production, pharmaceutical and chemical processing environments where media compatibility and corrosion resistance are important.

Dial sizes within the range typically include compact 40mm and 50mm gauges for restricted installations through to larger 100mm and 160mm variants where improved visibility is required within plant rooms and industrial equipment. Bottom entry and back entry configurations are available to support different mounting layouts including direct mounting, panel mounting and surface mounting applications.

Pressure ranges are available from vacuum and compound scales through to high-pressure industrial applications. Standard BSP, BSPT and NPT process connections are commonly supplied to support compatibility with industrial pipework and equipment connections.

Many glycerine filled pressure gauges can also be supplied with calibration certificates where traceability and documented verification are required for maintenance procedures, quality systems or industrial process applications.

Whether used for hydraulic systems, compressors, process equipment or industrial maintenance, selecting the correct glycerine filled pressure gauge helps improve reading stability, operational reliability and long-term gauge performance within demanding environments.

Understanding Glycerine Filled Pressure Gauges

Glycerine filled pressure gauges are mechanical pressure indicators designed for applications where vibration, pulsation or mechanical shock can affect gauge readability and service life. Unlike standard dry gauges, glycerine filled gauges contain liquid within the case to dampen movement of the internal mechanism and pointer.

Most industrial pressure gauges use a Bourdon tube sensing element to convert pressure into pointer movement. In vibrating systems or applications with fluctuating pressure, the pointer on a dry gauge can oscillate rapidly, making readings difficult to interpret and increasing wear on the movement mechanism. Glycerine filling reduces this movement to provide a steadier and easier-to-read indication.

Glycerine filled gauges are commonly used on hydraulic systems, pumps, compressors, mobile machinery and industrial plant equipment where pressure pulsation is present. These gauges are particularly useful within environments where machinery vibration or operational shock may shorten the lifespan of conventional dry pressure gauges.

Industrial glycerine filled pressure gauges are available in both brass-internal and all stainless steel constructions. Brass wetted part gauges are suitable for many standard pneumatic and hydraulic applications, while stainless steel gauges offer improved resistance to corrosive media and harsher process environments.

Dial sizes range from compact 40mm gauges through to larger 160mm industrial variants depending on visibility requirements and installation constraints. Bottom entry and back entry configurations support different mounting orientations and equipment layouts.

Connection sizes commonly include 1/8", 1/4", 3/8" and 1/2" BSP alongside NPT options on selected models. Vacuum, compound and high-pressure ranges are available depending on the application requirements.
