Ashcroft 83202 Pressure Gauge 600 Psi 3.5 in Npt

Product Description

The ASHCROFT 83202 is an analog pressure gauge designed for accurate pressure monitoring in mechanical, plumbing, HVAC, and industrial service applications. It features a 3.5-inch dial face with a 0 to 600 psi range and a stainless steel case for corrosion resistance in demanding environments. The liquid-filled design dampens needle vibration, improving readability on systems with pulsating pressure. Accuracy is rated at 1 percent of full scale. The 1/4-inch NPT center back mount connection makes it straightforward to install in-line or on a panel-mounted manifold. Licensed tradespeople in plumbing, HVAC, and mechanical contracting are the primary installers of this gauge.

This gauge suits residential and light commercial applications where a durable, readable pressure display is required. Common installations include boiler systems, compressed air lines, water supply and distribution piping, chilled water loops, and hydronic heating circuits. The center back mount orientation is well suited for panel boards and piping configurations where a front-facing, flush-mounted gauge is preferred. The stainless steel case holds up in wet or corrosive environments, making it a practical choice for mechanical rooms and outdoor-accessible utility systems.

• 3.5-inch analog dial for clear, at-a-glance readings
• Liquid-filled case reduces needle vibration on pulsating systems
• Stainless steel case provides corrosion resistance in wet or harsh environments
• 1/4-inch NPT center back mount for straightforward panel or pipe installation
• 1 percent of full-scale accuracy for reliable pressure readings

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and commercial mechanical systems using 1/4-inch NPT center back mount connections with a 0 to 600 psi pressure range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC mechanic in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and depressurize the system fully before removing or installing the gauge. Apply thread sealant tape to the NPT threads, taking care not to over-tighten, which can crack the gauge body or distort the socket. Verify that the system operating pressure does not continuously exceed the rated maximum to protect gauge accuracy and service life.
