Ashcroft 95090XLL Pressure Gauge 2.5 in 30-0-300 Psi

Product Description

The ASHCROFT 95090XLL is an analog pressure gauge built for demanding trade applications where accurate readings and corrosion resistance are critical. Featuring a 2.5-inch dial and stainless steel case with stainless steel wetted parts, this gauge delivers 1% of scale accuracy across a compound range of 30 to 0 to 300 psi. It mounts from the lower port using a 1/4-inch threaded connection, making it straightforward to install in-line or on a manifold. HVAC techs, plumbers, and industrial service pros rely on gauges like this for pressure testing, system monitoring, and routine diagnostics on both liquid and gas systems.

This gauge is suited for residential and light commercial applications where a compact, dry-fill instrument is needed. The compound pressure range covers both vacuum and positive pressure, making it useful for refrigeration suction-side monitoring, water pressure checks, and compressed air systems. The stainless steel wetted parts resist corrosion from mildly aggressive media, extending service life in wet or chemically active environments. Lower-mount configuration fits standard tee fittings and valve ports commonly found in plumbing and HVAC installations.

Key Features

• Compound range of 30 to 0 to 300 psi covers both vacuum and positive pressure readings
• 1% of scale accuracy for reliable diagnostic and monitoring use
• Stainless steel case and wetted parts resist corrosion and physical damage
• 2.5-inch analog dial provides clear, easy-to-read graduations
• Lower-mount, 1/4-inch threaded connection fits common trade fittings
• Dry-fill construction — no liquid fill — reduces mess during installation and service

Compatibility

Designed as an OEM-style replacement or direct-fit instrument gauge for residential and commercial HVAC, plumbing, and refrigeration systems requiring a 1/4-inch lower-mount analog pressure gauge.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified service professional. Always isolate and depressurize the system before removing or installing any pressure gauge. Use appropriate thread sealant or PTFE tape on the 1/4-inch male threads and avoid overtightening, which can crack the gauge socket. Verify the system pressure range falls within the 30 to 300 psi scale before applying pressure.
