Ashcroft 92867 Pressure Gauge 0-400 Psi 6 Inch Dial Npt

Product Description

The ASHCROFT 92867 is an analog pressure gauge designed for industrial and mechanical system monitoring where accurate, reliable pressure readings are required across a range of 0 to 400 psi. Featuring a 6-inch dial with a glass lens, this gauge uses a bronze Bourdon tube sensing element housed in an aluminum case. The lower-mount configuration accepts a 1/4-inch NPT connection, making it straightforward to install in piping systems without additional fittings in most applications. Accuracy is rated at 0.25 percent of scale, which meets the demands of process control, HVAC hydronic systems, compressor monitoring, and similar trade applications.

This gauge is suited for residential and light commercial plumbing, HVAC hydronic loops, compressed air systems, and general mechanical service work where a durable, large-dial analog gauge is needed. The 6-inch dial size improves readability at a distance, making it practical for boiler rooms, mechanical rooms, and equipment rooms where gauges are mounted away from eye level. The lower-mount NPT fitting integrates directly into standard pipe fittings and gauge valves common to these installations. It carries a CRN certification, indicating suitability for use in Canadian pressure vessel and piping applications.

Key Features

• 0 to 400 psi pressure range suitable for compressed air, hydraulic, and hydronic monitoring
• 0.25 percent of scale accuracy for precise pressure readings
• 6-inch analog dial with glass lens for clear, wide-angle readability
• Bronze Bourdon tube for durability with common process media
• Aluminum case construction reduces overall weight
• Lower-mount 1/4-inch NPT connection for direct pipe installation
• CRN certified for Canadian pressure system compliance

Compatibility

Designed as an OEM-style and aftermarket analog pressure gauge for mechanical piping systems using standard 1/4-inch NPT lower-mount gauge ports in plumbing, HVAC, and compressed air applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Relieve all system pressure and isolate the gauge port before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per standard practice, and hand-tighten before applying final torque with a wrench on the gauge hex only — never use the case body as a turning point. Reference applicable local codes and the ASME B40.100 gauge standard for installation requirements.
