Value Brand 4FMP8 Pressure Gauge Test 3-1/2 In

Purpose and fit

This pressure gauge is built for general-purpose testing where a 3-1/2 inch dial and 1/4 inch NPT male bottom connection are required. It suits technicians who need a stainless-steel cased instrument with an acrylic lens for standard industrial or automotive pressure checks. Buyers needing panel mounting, hazardous-location ratings or a different process connection size should look elsewhere.

Deciding specification

The gauge uses a 316 stainless steel sensor and socket with a 304 stainless steel case, delivering an accuracy of plus or minus 3-2-3 percent across the scale. The 1/4 inch NPT male bottom connection determines whether it fits the intended port without adapters. No IP, NEMA or hazardous-location rating is provided, so it is not suited for sealed or classified environments.

Thermals noise and power

As a purely mechanical dial gauge it has no power draw, produces no audible noise and generates no heat during operation. The 304 stainless steel case and acrylic lens are rated for typical ambient conditions encountered in commercial pressure testing. No active cooling or external supply is required.
