Ashcroft 63108S2LLLV/300 Pressure Gauge 0-300 Psi

Product Description

The ASHCROFT 63108S2LLLV/300 is an analog pressure gauge with a 2.5-inch dial, designed for direct-reading pressure measurement in industrial, mechanical, and trade service applications. It reads from 0 to 300 psi and features a stainless steel case with stainless steel wetted parts, making it suitable for use in corrosive or washdown environments. The gauge uses a lower-mount connection, meaning the port exits from the bottom of the case, and accepts a 1/4-inch threaded fitting for inline installation. Accuracy is rated at 3-2-3 percent of scale across the dial range. Licensed tradespeople including HVAC technicians, plumbers, and pipefitters install this gauge for pressure monitoring on equipment, pipelines, and process systems.

This gauge is suited for residential and light commercial mechanical systems where a compact, corrosion-resistant dial gauge is required. Common applications include pressure monitoring on water systems, refrigeration circuits, compressed air lines, hydraulic circuits, and general process piping. The lower-mount configuration makes it a practical fit for vertical pipe risers and manifold ports where the gauge needs to read upright. The no-fill, dry dial design avoids compatibility issues with system fluids or glycol-filled instrument concerns.

Key Features

• 0 to 300 psi pressure range with analog dial readout
• 2.5-inch dial diameter for clear at-a-glance readings
• 3-2-3 percent of scale accuracy across the full range
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• Lower-mount connection with 1/4-inch thread for bottom-entry installation
• Dry (no-fill) design eliminates fluid compatibility concerns

Compatibility

Designed as an OEM-style or replacement analog pressure gauge for general-purpose mechanical and process piping systems accepting a 1/4-inch lower-mount threaded connection.

Installation Notes

Installation should be performed by a qualified trades professional such as a licensed plumber, pipefitter, or HVAC technician. Always isolate and depressurize the system before removing or installing any pressure gauge. Apply appropriate thread sealant to the male threads per the system fluid and pressure requirements; do not overtighten, as this can damage the gauge socket. Verify the gauge pressure range is appropriate for the system before returning the system to service.
