304SS 2.5" 0-3,000 PSI/ 0-210 Bar Liquid Filled Pressure Gauge, 1/4 NPT Bottom Connection

Ask A Question

Description & Features

Liquid filling dampens needle vibration and protects internal components in high-pulsation environments, making this gauge well suited for compactor and hydraulic pressure monitoring applications. The 304SS 2.5" 0-3,000 PSI / 0-210 Bar Liquid Filled Pressure Gauge, 1/4 NPT Bottom Connection is manufactured by Engineered Specialty Products (ESP) with a stainless steel construction and a brass male connection fitted with a 0.013" throttle plug. The polycarbonate window provides a clear view of the dual-scale dial, which reads from 0–3,000 PSI and 0–210 Bar. Accuracy is rated at ±3-2-3% of span, meaning ±3% over the first and last quarters of the scale and ±2% over the middle half. For reliable service life, normal operating pressure should be kept between 25% and 75% of full scale; in pulsating systems, maximum operating pressure should not exceed 50% of the full-scale range. Compact dimensions (A=2.48", B=1.21", C=2.71", D=0.46") allow installation in space-constrained configurations. The 1/4 NPT bottom connection is a standard fit across a wide range of hydraulic and industrial equipment.

Product Questions & Answers (1)

Question by: Dale B on Aug 18, 2025, 5:26 PM
got a compactor running pretty hard and the needle bounces all over the place on my current gauge, would this liquid-filled one settle that down?
Answer by: Customer Support on Aug 20, 2025, 8:10 AM
Liquid filling does exactly that. The glycerin or similar fill inside the case slows the needle movement so it reads steady even when pressure is spiking and dropping fast. Compactor applications are actually one of the main uses this gauge is built for, so it's a solid match for what you're describing. Just keep in mind that on pulsating systems like yours, you'll want your normal working pressure to stay at or below 50% of the 3,000 PSI full scale. Running it above that range in a high-pulse environment will shorten the gauge's service life.
