Value Brand Pressure Gauge 4CFL8 Liquid Filled 1-1/2 In measurement tool

1-1/2 In Liquid-Filled Pressure Gauge

This 1-1/2 inch nominal dial gauge is built for commercial pressure measurement with a liquid-filled design that resists vibration. The 304 stainless steel case and acrylic lens provide durability, while the center-back male NPT connection allows direct mounting on compatible ports. It suits technicians who need a reliable, field-ready instrument for monitoring system pressure up to 300 units.

Compatibility check before ordering

Verify that your process connection accepts a 1/8 inch male NPT thread and that a center-back mounting orientation fits the available space. The gauge is not field-fillable, so the liquid dampening is factory-set and cannot be adjusted on site. Confirm the primary pressure range of 0 to 300 matches your application and that the +/-3-2-3 percent accuracy class meets your tolerance requirements.

Upgrade from dry gauges or lower-range models

Replacing a dry gauge with this liquid-filled version reduces pointer flutter in high-vibration environments, improving readability and extending service life. The step up is worthwhile when vibration resistance is critical or when the 300-unit range covers pressures your current gauge cannot. Buyers needing a field-fillable case, a different connection size, or an IP-rated enclosure should look elsewhere.
