304SS 2.5" 30Hg-15 PSI/ -1.0 - 1.0 Bar Liquid Filled Pressure Gauge, 1/4 NPT Bottom Connection

Description & Features

Maximize precision with the 2.5" liquid filled pressure gauge engineered with high-grade 304 stainless steel. Ideal for demanding industrial environments it covers a range of 30Hg to 15 PSI or -1.0 to 1.0 Bar.

Designed by Engineered Specialty Products the robust construction incorporates a 1/4 NPT bottom connection for seamless integration. The polycarbonate window ensures clarity and durability complemented by a brass male connection featuring a 0.013" throttle plug.

Accuracy is ensured across the span with a tolerance of 3-2-3%. The gauge is liquid filled enhancing stability and reducing needle flutter making it suitable for applications with fluctuating pressures.

To maintain optimal performance it is recommended that the operating pressure be kept within 25%-75% of the gauge scale and not exceed 50% if pulsation is present.

Product Questions & Answers (3)

Question by: Ricky G on May 15, 2025, 4:58 PM

Can this handle a little vibration, or does it need to be mounted somewhere real stable?

Answer by: Customer Support on May 17, 2025, 3:08 PM

Liquid filling helps dampen vibration and pulsations, so it should give you more stable readings even if things aren't perfectly still. Keep the pressure within 25%-75% of the scale for the best performance, and under 50% if you've got a lot of vibration.

Question by: Steve H on Feb 7, 2026, 10:57 AM

gauge reads vacuum and positive pressure both, that what the 30Hg to 15 PSI range means, or am i reading that wrong?

Answer by: Customer Support on Feb 8, 2026, 7:47 PM

You're reading it right. That range covers both sides of atmospheric pressure. The negative side goes down to 30 inches of mercury, which is full vacuum, and the positive side tops out at 15 PSI. So if your process pulls a vacuum and then pressurizes, this one gauge handles the whole swing without needing two separate instruments.

Question by: Brett H on Apr 9, 2025, 2:03 PM

got a system that bounces around a bit, will this gauge quit flutterin all over the place?

Answer by: Customer Support on Apr 11, 2025, 6:16 AM

Liquid fill helps steady the needle when pressure is fluctuating, so it is a good fit for systems that tend to pulse or vibrate. For best results, keep normal operating pressure in the 25% to 75% part of the scale, and if pulsation is present do not run it over 50% of full scale.
