Ashcroft 93112XLL Pressure Gauge 0-200 Psi 4.5 in Dial

Product Description

The ASHCROFT 93112XLL is a process industrial pressure gauge designed for accurate pressure monitoring in demanding industrial and mechanical systems. Featuring a 4.5-inch analog dial with a 0 to 200 psi range, it delivers 0.5% of scale accuracy, making it suitable for applications where precise readings are required. The gauge uses a 1/4-inch MNPT center back mount connection, a glass lens, an aluminum case, and bronze wetted parts. It ships dry with no liquid fill. Licensed HVAC technicians, plumbers, and industrial maintenance professionals install this gauge on process lines, pneumatic systems, and fluid distribution equipment.

This gauge is appropriate for process and industrial installations in both commercial and light industrial environments. The center back mount configuration suits panel-mounted or inline installations where the gauge face needs to be flush and readable from a direct line of sight. The 4.5-inch dial size ensures clear readability in low-light or high-activity work areas. Its aluminum case keeps weight low at 2.5 pounds while maintaining structural integrity. The bronze wetted parts are compatible with a wide range of non-corrosive process media commonly encountered in HVAC, plumbing, and general industrial service.

Key Features

• 0.5% of scale accuracy rating for reliable, repeatable readings
• 1/4-inch MNPT center back mount for straightforward panel or inline installation
• Aluminum case construction keeps the unit lightweight at 2.5 pounds
• Bronze wetted parts suitable for common non-corrosive process media
• Glass lens with no liquid fill; meets CRN and IP66/NEMA 4X standards

Compatibility

Designed as an OEM-style process pressure gauge replacement for industrial and commercial systems requiring a 1/4-inch MNPT center back mount gauge with a 4.5-inch dial in the 0 to 200 psi range.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with pressurized piping systems and applicable codes such as the IPC or IFGC. Shut off and depressurize the system fully before removing the existing gauge or installing this unit. Apply appropriate thread sealant to the MNPT threads per the system requirements, and do not overtighten, as the aluminum case and bronze fitting can be damaged by excessive torque. Verify the gauge reads zero with no system pressure before returning the system to service.
