Ashcroft 351009S2BLL7.5K Pressure Gauge 0-7500 Psi 3.5 in

Product Description

The ASHCROFT 351009S2BLL7.5K is an analog pressure gauge rated for a pressure range of 0 to 7500 psi, built for demanding trade and industrial service applications. The gauge features a 3.5-inch dial diameter for clear field readability, a stainless steel case, and stainless steel wetted parts for corrosion resistance in harsh media environments. Accuracy is rated at 1 percent of full scale, meeting standard requirements for most mechanical system monitoring tasks. It mounts via a 1/4-inch center back connection, keeping the dial face forward and unobstructed in panel or pipe installations. No liquid fill is used, making it suitable for clean-media, non-pulsating service conditions.

This gauge is well suited for HVAC high-side and low-side pressure monitoring, plumbing and hydronic system testing, compressed air systems, and light industrial process lines where stainless wetted parts are required to resist corrosion from water, refrigerants, or mild chemicals. The center back mount configuration is commonly used in panel-mounted applications and instrument manifolds where a flush or bracket installation is preferred. Licensed HVAC technicians, plumbers, and mechanical contractors are the primary installers of this type of instrument.

Key Features

• 0 to 7500 psi pressure range for high-pressure system monitoring
• 3.5-inch analog dial for clear, at-a-glance readings in the field
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 1 percent of full scale accuracy for reliable system diagnostics
• 1/4-inch center back mount for panel and manifold installations
• Non-liquid-filled design suited for clean, low-pulsation service

Compatibility

Designed as an OEM-style replacement or new-installation analog pressure gauge for use in HVAC, plumbing, compressed air, and light industrial process systems requiring a 1/4-inch center back mount connection and stainless steel wetted components.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or qualified mechanical contractor. Isolate and depressurize the system completely before removing any existing gauge or installing this unit. Apply appropriate thread sealant to the 1/4-inch NPT connection per local plumbing or mechanical codes, and do not over-torque the fitting into the port. Verify the system pressure range does not exceed the gauge maximum of 7500 psi during operation.
