Ashcroft 93005XLL Pressure Gauge 4.5 in Dial 0-30 Psi

Product Description

The ASHCROFT 93005XLL is an analog pressure gauge designed for accurate pressure monitoring in fluid and gas systems. It features a 4.5-inch dial with a 0 to 30 psi range and delivers 0.5 percent of scale accuracy, making it suitable for applications that require reliable, easy-to-read indication. The gauge mounts via rear flange and connects through a 0.25-inch threaded port. The thermoplastic case keeps weight low and resists corrosion in typical service environments. This gauge is installed by licensed plumbers, HVAC technicians, and mechanical contractors during system commissioning, service, or permanent monitoring installations.

This gauge is suited for residential and light commercial plumbing, HVAC, and pneumatic systems where a dry, non-liquid-filled instrument is appropriate. The 4.5-inch dial face provides clear readability at a distance, which is useful in mechanical rooms or utility spaces. The rear flange mount configuration allows the gauge to be panel-mounted or surface-mounted flush to a control enclosure or pipe board. No liquid filler is used, keeping the unit straightforward for standard ambient-temperature service conditions.

Key Features

• 4.5-inch analog dial for high-visibility pressure reading
• 0 to 30 psi pressure range suitable for low-pressure fluid and gas monitoring
• 0.5 percent of scale accuracy for reliable indication
• Rear flange mount for panel or surface installation
• 0.25-inch threaded connection for standard pipe fittings
• Dry, no-fill thermoplastic case — lightweight and corrosion-resistant

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for residential and light commercial plumbing, HVAC, and pneumatic systems requiring a dry analog gauge with rear flange mount and 0.25-inch thread connection.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable IPC or IFGC requirements. Depressurize and isolate the system completely before removing any existing gauge or making threaded connections. Use thread sealant or PTFE tape on the male threads and tighten to snug-plus-hand-tight without over-torquing the thermoplastic case. Verify the system pressure range does not exceed the gauge full-scale rating before returning the system to service.
