Ask A Question

Description & Features

The 304SS 2.5" 0-1 000 PSI/ 0-70 Bar Liquid Filled Pressure Gauge with 1/4 NPT center back connection is crafted for precise measurements. Suitable for various industrial applications it combines durability with reliable performance.

This gauge from Engineered Specialty Products utilizes a liquid-filled design to mitigate needle flutter and vibration ensuring accurate readings. The stainless steel material offers excellent resistance to corrosion enhancing longevity in demanding environments.

It features a polycarbonate window for clear visibility and an accuracy of 3-2-3% across the scale. The pressure gauge recommends normal operating pressure be confined to 25%-75% of the scale for optimal performance.

The male connection is designed with brass and includes a 0.013" throttle plug. Dimensions are as follows: A=2.48 B=1.21 C=2.71 making it compact yet efficient.

What's the deal with the accuracy on this thing? Is it spot-on, or what?
Answer by: Customer Support on Jan 10, 2026, 11:58 AM
The accuracy is rated at ±3-2-3% of the full scale. That means you'll see ±3% accuracy over the first and last quarters of the scale, and ±2% accuracy over the middle half.

Running this on a hydraulic system that throws a fair amount of vibration and pulsation. how much of the scale am I actually supposed to be working in on a day-to-day basis?
Answer by: Customer Support on Apr 7, 2026, 7:10 PM
For normal steady operation, keep your working pressure between 25% and 75% of the full scale, so roughly 250 to 750 PSI on this gauge. If your system has pulsation, that upper limit drops further. Under pulsating conditions, you want to stay at or below 50% of the full scale range, which puts your ceiling at 500 PSI. The liquid fill helps settle needle flutter, but it does not change those operating pressure guidelines.

need a gauge that’ll quit bouncing around when the pump kicks on. is this one liquid filled for that?
Answer by: Customer Support on Jun 24, 2025, 6:05 AM
Liquid fill helps dampen vibration and needle flutter, so the reading stays steadier when you have pulsation or general shake in the system.
