Ashcroft 95436XLL Pressure Gauge 0-30 Psi Center Back Mount

Product Description

The ASHCROFT 95436XLL is a dry analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and industrial piping applications. It features a 3.5-inch dial with a 0 to 30 psi range, delivering 1% of scale accuracy across that span. The stainless steel case protects internal components in corrosive or wet environments, while bronze wetted parts provide reliable contact with common fluid media. It mounts via a 1/4-inch center back connection, making it suitable for panel installations and inline service points. Licensed plumbers, HVAC technicians, and pipefitters install this gauge as a permanent or service-check instrument on low-pressure systems.

This gauge is suited for residential and light commercial applications where low-range pressure monitoring is required. Typical installations include domestic water supply lines, boiler systems, compressed air headers, and low-pressure gas service verification points. The center back mount configuration allows flush panel or bracket installation where a front-mounted stem would obstruct access. The dry, no-fill design simplifies installation and avoids glycerin or silicone compatibility concerns in sensitive fluid systems.

Key Features

• 0 to 30 psi analog pressure range with 1% of scale accuracy
• 3.5-inch dial for clear readability at typical working distances
• Stainless steel case resists corrosion in wet or outdoor service environments
• Bronze wetted parts compatible with water, air, and common non-aggressive media
• 1/4-inch center back mount for panel flush installation
• Dry gauge construction with no liquid fill for simplified serviceability

Compatibility

Designed as an OEM-style replacement or new-install pressure gauge for residential and light commercial low-pressure plumbing, HVAC, and compressed air systems requiring a 1/4-inch center back mount connection.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. Isolate and depressurize the system completely before removing an existing gauge or making the threaded connection. Apply thread sealant tape or pipe compound appropriate for the media being monitored, and hand-tighten before snugging with a wrench — do not overtighten a brass or bronze threaded port. Verify the gauge reads zero at atmospheric pressure before returning the system to service.
