Ashcroft 94886XLL Pressure Gauge 0-15 Psi 2.5in Dial

Product Description

The ASHCROFT 94886XLL is an industrial-grade analog pressure gauge designed for accurate pressure monitoring across a wide range of mechanical and process systems. It features a 2.5-inch dial with a 0 to 15 psi range and delivers 1% of scale accuracy, making it suitable for applications that demand reliable readings without liquid fill. The stainless steel case and stainless steel wetted parts offer solid corrosion resistance in demanding service environments. This gauge installs via a 1/4-inch MNPT center back mount connection, a common configuration for panel-mounted and inline installations. Plumbers, HVAC technicians, and industrial maintenance professionals regularly specify this gauge type for low-pressure system monitoring.

This gauge is well suited for residential and light commercial plumbing systems, HVAC hydronic circuits, compressed air lines, and industrial process lines operating in the 0 to 15 psi range. The center back mount configuration makes it compatible with standard panel cutouts and back-mount gauge manifolds. Its dry, no-fill design simplifies installation in environments where liquid-filled gauges are not required or preferred. The polycarbonate lens provides good visibility and impact resistance in field conditions.

Compatibility

Designed as an OEM-style or replacement industrial pressure gauge for low-pressure plumbing, HVAC hydronic, and process piping systems using 1/4-inch MNPT center back mount gauge ports.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial maintenance technician. Shut off system pressure and bleed residual pressure before removing or installing any gauge. Apply thread sealant or PTFE tape to the MNPT threads per standard practice, and avoid over-tightening to prevent case or port damage. Verify the gauge pressure range is appropriate for the system before placing into service.
