304SS 2.5" 0-4,000 PSI/ 0-280 Bar Liquid Filled Pressure Gauge, 1/4 NPT Bottom Connection

Description & Features

This precision-engineered liquid filled pressure gauge provides accurate readings from 0 to 4 000 PSI (0-280 Bar). Crafted with robust 304 stainless steel it ensures enhanced durability for demanding applications. A 2.5-inch dial coupled with a brass 1/4 NPT bottom connection delivers reliable performance and easy installation across various industrial settings.

With an accuracy of 3-2-3% of span this gauge guarantees precise measurement over the full scale range. The polycarbonate window offers clear visibility while the liquid filling helps dampen pulsation effects for optimal performance even in challenging conditions. Recommendations suggest confining normal operating pressure to 25%-75% of the scale to maintain accuracy and extend lifespan.

This gauge is ideal for industries requiring dependable and long-lasting pressure measurement solutions. The brass male connection includes a 0.013" throttle plug further enhancing its robustness for intensive use.

Question by: Neal M on Mar 22, 2026, 8:46 PM

got a 1/4 npt port on the bottom of my gauge block. is this one a bottom mount with a male fitting or am i gonna need adapters?

Answer by: Customer Support on Mar 24, 2026, 6:46 AM

Comes with a 1/4 NPT bottom connection and it is a male brass fitting, so it threads into a female 1/4 NPT port. It also includes a 0.013 inch throttle plug in that male connection.

Question by: Scott W on Dec 15, 2025, 3:41 PM

Running a hydraulic press that gets pretty rough pulsation through the lines, will the liquid fill actually help keep the needle steady, or is that more of a marketing thing?

Answer by: Customer Support on Dec 17, 2025, 9:05 AM

Liquid filling makes a real difference in pulsating systems. The glycerin or similar fill dampens needle movement so you get a readable, stable display instead of a needle bouncing all over the place. That said, if pulsation is present in your process, keep your operating pressure at or below 50% of full scale. On a 4,000 PSI gauge, that means staying under 2,000 PSI in those conditions. The brass connection also includes a 0.013" throttle plug, which further reduces pressure spikes reaching the internals.

Question by: Lance T on Apr 9, 2025, 5:25 PM

What size is the thread on this gauge?

Answer by: Customer Support on Apr 11, 2025, 7:02 AM

The thread is a 1/4 NPT.
