Ashcroft 92957XLL Pressure Gauge 0-15 Psi 4.5 in Dial

Product Description

The ASHCROFT 92957XLL is a process industrial pressure gauge designed for accurate pressure monitoring in demanding industrial and mechanical system applications. It features a 4.5-inch analog dial with a 0 to 15 psi range and delivers 0.5 percent of scale accuracy. The thermoplastic case and glass lens provide durability in wet or wash-down environments, supported by an IP66 and NEMA 4X enclosure rating. The gauge uses a 1/4-inch MNPT rear flange mount connection, making it suitable for panel or wall-mounted installations. It ships dry with no liquid fill. Licensed HVAC technicians, plumbers, and industrial mechanics typically install this gauge during system commissioning or routine instrumentation replacement.

This gauge is well-suited for residential and light commercial HVAC systems, plumbing systems, and process piping where low-range pressure readings up to 15 psi must be monitored continuously. The rear flange mount configuration allows flush or panel mounting in control enclosures and mechanical rooms. The 4.5-inch dial provides clear readability from a distance, which is practical in boiler rooms, pump stations, or chiller plants where instrumentation is viewed regularly during service rounds.

Key Features

• 0 to 15 psi analog pressure range with 0.5 percent of scale accuracy
• 4.5-inch dial diameter for clear, at-a-glance readability
• Thermoplastic case rated IP66 and NEMA 4X for wet and wash-down environments
• Glass lens for scratch resistance and long-term dial clarity
• 1/4-inch MNPT rear connection with flange mount for panel installation
• Dry gauge, no liquid fill required
• CRN certified for applicable Canadian pressure vessel regulations

Compatibility

Designed as an OEM-style replacement or new-install process pressure gauge for industrial, HVAC, and plumbing piping systems requiring a 1/4-inch MNPT rear flange mount gauge in the 0 to 15 psi range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation technician. Isolate and depressurize the system completely before removing or installing any pressure gauge. Apply appropriate thread sealant to the MNPT connection per local code requirements and tighten to hand-tight plus the manufacturer-recommended turns without over-torquing the thermoplastic case. Verify the system pressure range does not exceed the gauge maximum before returning the system to service.
