Ashcroft 94601XLL Pressure Gauge 3.5 in 0-160 Psi Lower Mount

Product Description

The ASHCROFT 94601XLL is a dry, analog pressure gauge built for accurate pressure monitoring in plumbing, HVAC, and industrial service applications. It features a 3.5-inch dial with a 0 to 160 psi range and delivers 1% of scale accuracy, making it suitable for system commissioning, troubleshooting, and ongoing pressure verification. The stainless steel case provides corrosion resistance in demanding environments, while the bronze wetted parts offer reliable compatibility with common system fluids. Installed via a 1/4-inch lower-mount thread connection, this gauge fits standard gauge ports found throughout commercial and residential mechanical systems. Licensed technicians and service professionals are the primary installers.

This gauge is suited for dry-service installations where liquid fill is not required. The lower-mount configuration positions the gauge directly above the process connection, making it a common choice for panel-mounted or pipe-mounted applications in HVAC equipment, compressed air systems, water supply lines, and general plumbing service points. The 3.5-inch dial provides a clear, readable analog display at close working distances, reducing misread risk during inspections and service calls.

Compatibility

Designed as an OEM-style replacement or service gauge for residential and commercial plumbing, HVAC, and compressed air systems using a 1/4-inch lower-mount gauge port with a 0 to 160 psi pressure range requirement.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Shut off and depressurize the system completely before removing the existing gauge or installing this unit. Apply thread sealant appropriate for the system fluid to the 1/4-inch male threads before installation. Do not over-tighten the gauge connection, as excessive torque can damage the brass socket or distort calibration.
