Ashcroft 80298XLL Pressure Gauge 0-150 Psi 4.5 in Mnpt

Product Description

The ASHCROFT 80298XLL is a process industrial pressure gauge designed for accurate pressure monitoring in demanding mechanical and industrial applications. It features a 4.5-inch analog dial with a 0 to 150 psi range and delivers 0.5% of scale accuracy. The gauge uses a 1/4-inch MNPT center back mount connection, making it straightforward to install in line with standard threaded process fittings. The aluminum case provides lightweight durability, and bronze wetted parts resist corrosion in typical process fluid environments. A glass lens protects the dial face. This gauge ships without liquid fill, suited for systems where a dry gauge is specified. Licensed HVAC technicians, plumbers, and industrial service professionals are the primary installers.

The ASHCROFT 80298XLL is used in residential, commercial, and light industrial process systems where reliable analog pressure indication is required. Its center back mount configuration suits panel-mounted or pipe-mounted installations where the gauge face must be flush or recessed into an enclosure. The 0 to 150 psi range covers a broad set of water, gas, and fluid-handling applications. The gauge carries CRN certification and an IP66/NEMA 4X environmental rating, making it appropriate for outdoor or wash-down service environments where moisture and dust ingress are concerns.

Key Features

• 4.5-inch analog dial with 0 to 150 psi pressure range for clear, at-a-glance readings
• 0.5% of scale accuracy meets process-grade measurement requirements
• Bronze wetted parts provide corrosion resistance in water and compatible fluid service
• Aluminum case keeps overall weight low at 2.5 pounds
• IP66/NEMA 4X rating protects against dust ingress and direct water exposure
• CRN certified for Canadian registered pressure vessel applications
• Dry gauge construction with no liquid fill for simplified maintenance

Compatibility

Designed as an OEM-style or replacement process pressure gauge for systems using 1/4-inch MNPT center back mount connections with a 0 to 150 psi service range. Suitable for water, air, gas, and compatible fluid-handling systems meeting the bronze wetted parts specification.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic. Depressurize and isolate the system completely before removing any existing gauge or installing this unit. Apply thread sealant tape or compound rated for the service fluid to the 1/4-inch MNPT threads. Do not over-torque the connection; use a wrench on the hex fitting body only, not on the case or dial.
