Ashcroft 662876116478 Pressure Gauge 0-200 Psi 3.5 in

Product Description

The ASHCROFT 662876116478 is a commercial-grade analog pressure gauge designed for general industrial and mechanical service applications. It features a 3.5-inch dial with a 0 to 200 psi range, a 1/4-inch NPT center back mount connection, and a steel case with a polycarbonate lens. The bronze Bourdon tube provides reliable pressure sensing across the full scale. Accuracy is rated at 3-2-3 percent of scale, meaning the middle portion of the dial holds tighter tolerance than the ends. Licensed HVAC technicians, plumbers, and mechanical contractors install this gauge on pressure systems, test manifolds, and equipment panels where a clear, durable dial indicator is required.

This gauge is suited for residential and light commercial applications where a mid-size dial and NPT back connection are standard. The center back mount configuration allows direct in-line installation on pipe fittings or manifold ports without a separate bracket. It is commonly used on boilers, compressors, pumps, and water distribution systems. The 1/4-inch NPT thread is one of the most common connection sizes across HVAC, plumbing, and refrigeration service equipment, making this gauge a practical fit for a wide range of service scenarios.

Key Features

• 3.5-inch analog dial with 0 to 200 psi range for clear, at-a-glance readings
• 3-2-3 percent of scale accuracy per ASHCROFT Series 1001T specification
• 1/4-inch NPT center back mount for direct pipe or manifold connection
• Steel case construction for durability in mechanical service environments
• Bronze Bourdon tube for corrosion resistance in typical water and air service
• Polycarbonate lens resists impact and provides a clear view of the dial face
• CRN certified for use in applicable Canadian pressure vessel applications

Compatibility

Designed as a direct-fit commercial pressure gauge for systems with 1/4-inch NPT center back mount ports rated within the 0 to 200 psi range. No specific OEM system compatibility was provided in the product data.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Always isolate and depressurize the system before removing or installing any pressure gauge. Apply an appropriate thread sealant to the NPT threads and hand-tighten before snugging with a wrench — do not overtighten, as this can crack the gauge body or distort the socket. Verify the gauge pressure range is appropriate for the system before placing it in service.
