Wika 50786431 Pressure Gauge 0-100 Psi 1-1/2 in Dial Npt

Product Description

The WIKA 50786431 is a 1-1/2 inch dial analog pressure gauge designed for inline pressure monitoring across HVAC, plumbing, and light industrial applications. It reads 0 to 100 psi on a single-scale dial with a 3-2-3 percent accuracy rating, meaning accuracy is within 3 percent at the low and high ends of the scale and 2 percent in the mid-range. The steel case houses brass wetted parts for durability and corrosion resistance in common fluid systems. A plastic lens protects the dial face. Licensed plumbers, HVAC technicians, and pipefitters typically install and service this gauge in pressurized fluid or gas monitoring points.

This gauge is suited for residential and light commercial installations where a compact, panel-mounted pressure indicator is needed. The 1/8 inch NPT center back connection allows direct pipe threading into a manifold, panel bulkhead, or tee fitting. The U-clamp panel mount design secures the gauge to a control panel or enclosure face, keeping the dial visible without additional brackets. It is a no-fill (dry) gauge, making it appropriate for systems where vibration and pulsation are not extreme concerns.

Key Features

• 0 to 100 psi single-scale pressure range
• 3-2-3 percent of scale accuracy across the full dial
• 1-1/2 inch dial diameter for compact panel installations
• 1/8 inch NPT center back connection for direct pipe mounting
• U-clamp panel mount for flush or panel-face installation
• Steel case with brass wetted parts and plastic lens

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and light commercial plumbing, HVAC, and fluid system panels requiring a 1/8 inch NPT center back mount with a 1-1/2 inch dial.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Depressurize and isolate the system before removing any existing gauge or threading in this unit. Apply appropriate thread sealant to the NPT connection per local plumbing codes; do not overtighten, as brass fittings are susceptible to thread damage. Secure the U-clamp hardware to the panel before pressurizing the system and verify there are no leaks at the connection point.
