2″ Diameter Pressure Gauge, Liquid Filled, 1/4″ NPT Male Brass Connection, Lower Mount, Stainless Steel Case

Campbell PG1T-L-SSB – 2″ Liquid-Filled Pressure Gauge with Stainless Steel Case and Lower Mount

The Campbell PG1T-L-SSB is a 2-inch diameter liquid-filled pressure gauge designed for reliable performance in demanding mechanical and industrial systems. This model features a stainless steel case for corrosion resistance and a 1/4″ NPT lower mount brass connection for compatibility with standard piping and manifold setups. The gauge’s glycerin-filled chamber stabilizes the pointer against vibration and pressure pulsation, providing consistent, readable measurements in variable operating conditions.

Application Overview

Suitable for hydraulic, pneumatic, water, and air systems, the PG1T-L-SSB is frequently used in compressors, pumps, regulators, and similar equipment where precision and vibration resistance are critical. Its durable construction and liquid damping make it appropriate for installations exposed to mechanical shock or moderate environmental stress.

Key Product Features

• Dial Size: 2 inches with clearly marked pressure indicators for quick visual reference
• Pressure Medium: Suitable for non-corrosive fluids and gases compatible with brass wetted parts
• Fill Type: Glycerin-filled to suppress needle fluctuation caused by system vibration or pulsing
• Case Material: 304 stainless steel for increased resistance to corrosion in wet or humid environments
• Connection: 1/4″ NPT male, brass, bottom (lower mount) for horizontal panel or direct equipment installation

Technical Specifications

• Model: PG1T-L-SSB
• Gauge Diameter: 2″ (50 mm)
• Connection Type: 1/4″ NPT brass, lower mount
• Case Material: Stainless steel (304 grade)
• Window Material: Polycarbonate
• Gauge Fill: Glycerin
• Intended Use: General purpose industrial and mechanical pressure monitoring

Installation Considerations

This gauge should be installed using appropriate sealing material (Teflon tape or pipe dope rated for pressure systems). Over-torqueing the brass connection may damage internal threads or deform the bourdon tube, so hand-tight plus one to two wrench turns is recommended. Mount the gauge vertically for optimal accuracy and liquid fill distribution. Avoid applications involving corrosive media unless all wetted parts are compatible.

Professional Use Notes

• Use in environments with low to moderate vibration for best performance
• Check compatibility of gauge internals with process media prior to installation
• Periodic recalibration may be required in high-cycle or mission-critical systems

Summary

The Campbell PG1T-L-SSB is a rugged, liquid-filled gauge designed to provide stable and accurate pressure readings in mechanical systems where vibration and pressure fluctuations are common. Built with a stainless steel case and brass connection, it meets industry expectations for general-purpose pressure instrumentation in HVAC, fluid handling, and compressed air installations.
