304SS 2.5" 30Hg-30 PSI/ -1.0-2.0 Bar Liquid Filled Pressure Gauge, 1/4 NPT Bottom Connection

Description & Features

Designed for precise monitoring this engineered specialty product offers reliable performance in industrial pressure measurement. The device features a robust 304 stainless steel construction for enhanced durability and corrosion resistance. With a 2.5-inch gauge diameter it measures pressure ranges from 30Hg-30 PSI / -1.0-2.0 Bar.

Equipped with a liquid-filled mechanism it ensures stable readings even under dynamic conditions. The bottom connection is a 1/4 NPT thread making it suitable for various applications where accurate pressure monitoring is essential. This gauge includes a brass male connection with a 0.013" throttle plug for added reliability.

The unit's accuracy is rated at 3-2-3% of span providing dependable measurements across a wide range. For optimal performance it is recommended to operate within 25%-75% of the scale and not exceed 50% if pulsation is present.

Other notable specifications include a polycarbonate window and specific dimensions (A=2.48 B=1.21 C=2.71 D=0.46). This makes it a versatile option for various industrial settings demanding precise pressure measurement and robust design.

Question by: Carl C on Oct 26, 2025, 9:19 PM

trying to replace a busted gauge. is this one the 2.5 inch face with the 1/4 npt bottom hook-up?

Answer by: Customer Support on Oct 27, 2025, 9:45 AM

Size-wise, it’s got a 2.5 inch face with a bottom connection that’s a 1/4 NPT. Perfect fit for your standard bottom-mount setting.

Question by: Howard F on Jul 6, 2025, 2:50 PM

On the scale, does it read vacuum and pressure, or just one or the other?

Answer by: Customer Support on Jul 9, 2025, 9:24 AM

The scale can read both. It indicates vacuum down to 30 inHg and pressure up to 30 PSI, along with a metric range of -1.0 to 2.0 bar.

Question by: Clint H on Jul 13, 2025, 10:21 AM

need to replace an old gauge on my pump. is the fitting on this one sticking out the back or the bottom? and what size thread we talking

Answer by: Customer Support on Jul 15, 2025, 8:52 AM

The 1/4 NPT brass connector is positioned at the bottom of the 2.5 inch dial, making it suitable for typical vertical installations.

Question by: Larry H on Oct 7, 2025, 1:42 PM

wondering about the dial readings on here. does it show both vacuum pull and positive pressure?

Answer by: Customer Support on Oct 9, 2025, 1:01 PM

The scale accounts for both vacuum and pressure. It descends to 30 inches of mercury for vacuum readings and rises to 30 PSI, with an additional metric range from -1.0 to 2.0 Bar.

Question by: Dwayne C on Oct 16, 2025, 9:41 PM

the liquid fill in this gauge, is that to help with vibration or what exactly does that do?

Answer by: Customer Support on Oct 18, 2025, 2:55 PM

The liquid fill minimizes needle jitters from vibration or pulsation, ensuring a steady reading in bumpy environments. It also keeps internal parts lubricated and shields them from moisture.

Question by: Hubert J on Apr 29, 2025, 4:57 PM

I need something that reads vacuum and pressure both - this one goes from 30 inches mercury vacuum up to 30 psi positive right

Answer by: Customer Support on May 2, 2025, 2:07 PM

That's right. This compound gauge tracks both vacuum and pressure, ranging from 30 inches of mercury in vacuum to 30 psi in pressure, and uses a metric scale of -1.0 to 2.0 bar.

Question by: Danny A on Aug 15, 2025, 5:38 PM

got a hydraulic system that runs around 20 psi, would this gauge handle that range without issues

Answer by: Customer Support on Aug 17, 2025, 11:47 AM

It spans from a vacuum at 30 inches of mercury to 30 psi, or between -1.0 and 2.0 bar, so 20 psi would fit comfortably within that performance range.
