Ashcroft 93116XLL Pressure Gauge 4.5 in 0-1000 Psi Back Mount

Product Description

The ASHCROFT 93116XLL is an analog pressure gauge designed for industrial and mechanical systems requiring accurate, reliable pressure monitoring. Featuring a 4.5-inch dial and a 0 to 1000 psi measurement range, this gauge delivers 0.5% of scale accuracy, making it suitable for demanding service applications. The center back mount configuration positions the connection at the rear of the gauge, allowing for clean panel or pipe installations. The aluminum case keeps weight low while providing durable housing, and bronze wetted parts offer solid corrosion resistance in a wide range of media. Licensed HVAC techs, plumbers, and mechanical contractors regularly specify this type of gauge for pressure monitoring on compressed air, gas, water, and hydraulic lines.

This gauge is well suited for both commercial and light industrial applications where a large, easy-to-read 4.5-inch dial face is needed. The center back mount makes it a practical choice for panel-mounted installations or installations where the supply line approaches from behind the gauge. The no-fill, dry dial design keeps maintenance minimal and eliminates concerns about glycerin or silicone fluid compatibility with the system media. Trades including plumbing, HVAC, and mechanical contracting commonly install this style of gauge on boilers, compressors, pumps, and process piping.

Key Features

• 4.5-inch analog dial for clear, at-a-glance pressure readings
• 0 to 1000 psi measurement range covers a wide range of mechanical applications
• 0.5% of scale accuracy for precise pressure monitoring
• Center back mount for clean panel or rear-pipe installations
• Bronze wetted parts provide corrosion resistance across common system media
• Aluminum case construction reduces overall gauge weight
• Dry, no-fill design requires no filler fluid maintenance

Compatibility

Designed as an OEM-style or direct-replacement pressure gauge for compressed air, gas, water, and hydraulic system applications requiring a 4.5-inch center back mount configuration with a 1/4-inch thread connection.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Always depressurize and isolate the system before removing or installing a pressure gauge. Use appropriate thread sealant on the 1/4-inch threaded connection and tighten to the fitting manufacturer's guidelines using a wrench on the gauge hex fitting, not the dial case. Verify the gauge pressure range is appropriate for the system's maximum operating pressure before placing the system back in service.
