Wika 4215818 Pressure Gauge 0-200 Psi 2 in Dial Npt

Product Description

The WIKA 4215818 is an analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and general industrial applications. It features a 2-inch diameter dial with a 0 to 200 psi range, making it well suited for moderate-pressure monitoring tasks. The steel case provides durable protection in typical mechanical room or panel environments, while brass wetted parts resist corrosion from common process media. Accuracy is rated at 3-2-3 percent of scale across the full range. The plastic lens keeps the dial face protected and readable. Licensed plumbers, HVAC technicians, and pipefitters commonly specify this gauge for panel-mount installations.

This gauge is intended for use in residential and light commercial systems where a compact, panel-mounted pressure indicator is required. The U-clamp panel center back mount configuration allows it to be secured directly to a panel or bracket, keeping the connection port centered at the rear of the gauge body. The 1/4-inch NPT back-mount connection makes it compatible with standard threaded ports on manifolds, pressure vessels, and piping assemblies. No liquid fill is used, making it appropriate for non-pulsating, vibration-free service conditions.

Key Features

• 2-inch analog dial with 0 to 200 psi single-scale range
• 3-2-3 percent of scale accuracy across the full pressure span
• Steel case construction for durability in mechanical environments
• Brass wetted parts for corrosion resistance with common process media
• U-clamp panel center back mount for secure panel installation
• 1/4-inch NPT connection for compatibility with standard threaded ports
• No-fill design suited for stable, non-pulsating pressure service

Compatibility

Designed as an OEM-style replacement or new-install analog pressure gauge for residential and light commercial plumbing, HVAC, and general-purpose piping systems requiring a 2-inch dial, 1/4-inch NPT back-mount gauge rated to 200 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauges. Depressurize and isolate the system completely before removing or installing the gauge. Apply thread sealant to the NPT threads per standard practice, but do not overtighten, as brass wetted components can be damaged by excessive torque. This gauge is rated for no-fill, non-pulsating service; installations with significant vibration or pressure spikes should use a snubber or consider a liquid-filled gauge.
