Compact, lead-free liquid-filled pressure gauge engineered for reliable pressure measurement in residential and light-commercial piping systems. The ILPG30025-4LNL combines a glycerine-filled movement and a crimped stainless steel ring to stabilize the pointer in high-vibration or corrosive environments while maintaining clear dial readability.

Range: 0–300 psi (engineering scale for general pressure applications).
Dial Size: 2½" (2.5-inch) easy-to-read dial with clear markings.
Case & Ring: Lead-free stainless steel case with crimped stainless steel ring for corrosion resistance.
Movement: Phosphor bronze Bourdon tube for accurate pressure sensing.
Filler: Glycerine (liquid-filled) to dampen vibration and protect internal components.
Connection: 1/4" lower male pipe threaded (MPT/MIP) connection for standard plumbing fittings.
Accuracy: Full-scale ±3% (mid-scale ±2%) for dependable readings.
Compliance & Lens: Lead-free (NSF/ANSI 372 compliant) with clear acrylic lens.
Media: Intended for use with air and water only; not for aggressive or combustible fluids.

This gauge is suitable for service on pumps, water systems, and general plumbing where vibration and corrosion are concerns. Its liquid fill and robust stainless-steel construction reduce pointer flutter for stable readings and longer service life. Refer to the manufacturer documentation for installation guidance, pressure range verification, and any safety or local code requirements before use.
