Ashcroft 662876151325 Pressure Gauge 0-160 Psi 3.5in

Product Description

The ASHCROFT 662876151325 is a commercial-grade analog pressure gauge designed for accurate pressure monitoring in mechanical, plumbing, and HVAC systems. It features a 3.5-inch dial with a 0 to 160 psi range and delivers 3-2-3 percent of scale accuracy across the full span. The gauge uses a bronze Bourdon tube sensing element housed in a steel case with a polycarbonate lens. The center back mount configuration and 1/4-inch NPT male connection make it straightforward to install on pipe fittings, manifolds, and equipment panels. Licensed HVAC technicians, pipefitters, and plumbers install this gauge where a clear, durable local pressure indication is needed.

This gauge is suited for residential and light commercial applications including boilers, chillers, compressors, pumps, and distribution piping. The center back mount orientation is commonly used on panel-mounted instrumentation and equipment headers where a direct rear connection keeps the installation compact. The analog dial provides a clear visual readout without the need for power or signal wiring, making it a reliable choice for a wide range of static and steady-state pressure monitoring points.

Key Features

• 3.5-inch analog dial for easy readout from a distance
• 0 to 160 psi range with 3-2-3 percent of scale accuracy
• Bronze Bourdon tube for corrosion resistance in common fluid and gas service
• Steel case with polycarbonate lens for durable, impact-resistant protection
• 1/4-inch NPT center back mount for compact panel and pipe installations
• CRN certified for use in pressure-bearing applications where Canadian Registration Number compliance is required

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for commercial and residential mechanical systems using standard 1/4-inch NPT back-mount connections in the 0 to 160 psi service range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes and ASME B40.100 gauge standards. Shut off and depressurize the system completely 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 a final quarter to half turn with a wrench on the gauge hex — do not use the case body as a wrench point. Verify the system pressure range does not exceed the gauge maximum before returning the system to service.
