Ashcroft 93698XLL Pressure Gauge 4.5 in Dial 0-200 Psi

Product Description

The ASHCROFT 93698XLL is an analog pressure gauge built for industrial and mechanical service applications. It features a 4.5-inch dial face for clear, at-a-glance readings and covers a range of 0 to 200 psi. The case is aluminum construction, and all wetted parts are bronze, making it suitable for a wide range of compatible media. Accuracy is rated at 0.5 percent of scale, which meets the demands of most commercial and industrial measurement tasks. The rear flange mount design allows the gauge to be flush-mounted directly to panels or enclosures. This gauge is not liquid-filled, making it appropriate for dry-service installations where vibration is not a primary concern.

This gauge is used in HVAC, plumbing, refrigeration, and industrial process applications where reliable pressure monitoring is required. The rear connection and flange mount make it a practical choice for panel-mounted instrumentation setups in mechanical rooms, equipment skids, and utility systems. Licensed HVAC technicians and plumbers commonly install this type of gauge on boilers, compressors, water supply lines, and similar pressurized systems.

Key Features

• 4.5-inch analog dial for easy reading at a distance
• 0 to 200 psi pressure range suitable for common mechanical system service
• 0.5 percent of scale accuracy for reliable measurement
• Bronze wetted parts provide broad media compatibility
• Aluminum case offers a lightweight, corrosion-resistant housing
• Rear flange mount enables direct panel or bulkhead installation
• No liquid fill — appropriate for low-vibration dry service environments

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and commercial mechanical systems requiring a 4.5-inch dial, rear flange mount configuration with a 1/4-inch threaded connection and a 0 to 200 psi range.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Depressurize and isolate the system completely before connecting or removing any pressure gauge. Apply thread sealant or PTFE tape to the 1/4-inch male threads per applicable code — do not overtighten, as this can damage the bourdon tube or crack the socket. For vibrating systems, consider a liquid-filled gauge or an isolation snubber to protect the movement.
