Ashcroft 95421XLL Pressure Gauge 0-15 Psi 2.5in Dial Mnpt

Product Description

The ASHCROFT 95421XLL is an analog industrial pressure gauge designed for accurate pressure monitoring in mechanical, HVAC, plumbing, and process piping systems. The gauge features a 2.5-inch dial with a 0 to 15 psi range and delivers 1% of scale accuracy, making it suitable for low-pressure applications where reliable readings matter. The stainless steel case is rated to IP54 and IP65/NEMA 4 for use in wet or dusty environments. A polycarbonate lens protects the dial face. Licensed HVAC technicians, pipefitters, and plumbers typically install this gauge on equipment where continuous visual pressure indication is required.

The 95421XLL is intended for industrial service on systems requiring a center back mount configuration with a 0.25-inch MNPT connection. The no-fill, dry bourdon tube design suits general-purpose installations where liquid-filled gauges are not required. Typical applications include air compressors, water lines, low-pressure gas distribution panels, and HVAC equipment headers where pressures remain at or below 15 psi. The 2.5-inch dial size provides a readable display at close range in panel or wall-mount installations.

Key Features

• 0 to 15 psi range with 1% of scale accuracy for precise low-pressure readings
• 2.5-inch analog dial for clear on-site pressure indication
• 304/316 stainless steel case rated IP54 and IP65/NEMA 4 for wet and dusty environments
• 316 stainless steel bourdon tube with bronze wetted parts for broad fluid compatibility
• 0.25-inch MNPT center back mount connection for direct pipe installation
• Polycarbonate lens with no-fill dry gauge construction for general-purpose service

Compatibility

Designed as an OEM-style replacement or new-installation industrial pressure gauge for systems requiring a 0.25-inch MNPT center back mount analog gauge rated to 15 psi. Compliant with CRN, IP54, IP65/NEMA 4, PED, and RoHS standards.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician following applicable local and national codes. Depressurize and isolate the system before removing or installing the gauge to prevent injury. Apply thread sealant appropriate for the service fluid to the MNPT threads before installation. Do not use pipe wrenches on the gauge case body; use a wrench only on the hex of the process connection fitting.
