Ashcroft 662876753781 Pressure Gauge 2.5 in 0-60 Psi Npt

Product Description

The ASHCROFT 662876753781 is a dry pressure gauge designed for monitoring system pressure in plumbing, HVAC, and light industrial applications. It features a 2.5-inch dial with a 0 to 60 PSI range and a lower-mount 1/4-inch NPT connection. The case is constructed from plastic, while all wetted internal parts are stainless steel, making it suitable for use with a wide range of fluids and gases. Accuracy is rated at 0.5 percent of scale across the full range. Licensed plumbers, HVAC technicians, and pipefitters commonly install this gauge at test ports, manifolds, and system service points where a compact, readable dial is required.

This gauge is well suited for residential and light commercial plumbing and HVAC systems where low-profile pressure monitoring is needed. The lower-mount NPT connection allows for direct installation into standard pipe fittings, manifold blocks, or test tees without additional adapters in most cases. Its black-faced dial and stainless steel wetted parts make it a practical choice for water supply lines, compressed air systems, and hydronic heating circuits where corrosion resistance at the wetted surface matters.

Key Features

• 2.5-inch dial diameter for clear, at-a-glance pressure reading
• 0 to 60 PSI pressure range suitable for low-to-mid pressure systems
• 1/4-inch NPT lower-mount connection for direct pipe or manifold installation
• Stainless steel wetted parts for corrosion resistance with common system fluids
• 0.5 percent of scale accuracy across the full pressure range
• Dry gauge construction — no liquid fill, reducing weight and simplifying disposal

Compatibility

Designed as an OEM-style or replacement pressure gauge for residential and light commercial plumbing, HVAC, and compressed air systems using standard 1/4-inch NPT lower-mount fittings.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauge installation. Depressurize and isolate the system before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the NPT threads before installation and tighten using an appropriately sized wrench on the gauge hex — do not torque through the gauge body or case. Verify the installed gauge range is appropriate for the system operating pressure before returning the system to service.
