Ashcroft 92645 Pressure Gauge 0-100 Psi 6 Inch Dial Npt

Product Description

The ASHCROFT 92645 is an analog pressure gauge designed for accurate pressure measurement in industrial, mechanical, and HVAC service applications. Featuring a 6-inch dial face, it delivers clear readability at a distance — a practical advantage in equipment rooms and mechanical spaces. The gauge covers a range of 0 to 100 psi with an accuracy of 0.25 percent of scale, making it suitable for demanding service work where precision matters. The lower-mount, 1/4-inch NPT connection allows direct inline installation on piping, manifolds, or test ports. A bronze Bourdon tube provides reliable pressure sensing, while the aluminum case keeps weight manageable at 5 pounds.

This gauge is well-suited for residential and light commercial HVAC systems, plumbing pressure testing, compressor monitoring, and general fluid or gas service where a 0 to 100 psi range is appropriate. The 6-inch dial size makes it a strong choice for panel-mount or standpipe installations where technicians need to read pressure from several feet away. The lower-mount NPT connection is a standard configuration compatible with typical service ports and isolation valves encountered in mechanical system work. It carries CRN certification, supporting use in Canadian regulated pressure applications.

Key Features

• 6-inch analog dial for clear, at-a-distance readability
• 0 to 100 psi range with 0.25 percent of scale accuracy
• 1/4-inch lower-mount NPT connection for standard inline installation
• Bronze Bourdon tube for durable pressure sensing
• Aluminum case construction for reduced weight
• Glass lens for scratch-resistant dial protection
• CRN certified for regulated pressure system applications

Compatibility

Designed as a standard replacement or new-installation analog pressure gauge for piping systems, HVAC equipment, and mechanical service applications requiring a 1/4-inch lower-mount NPT connection and a 0 to 100 psi measurement range.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or pipefitters. Isolate and depressurize the system fully before removing any existing gauge or fitting the new one. Apply appropriate thread sealant or PTFE tape to the NPT threads — do not overtighten, as aluminum cases can be damaged by excessive torque. Verify the system pressure range does not exceed the gauge maximum before returning the system to service.
