Ask A Question

Description & Features

The 304 stainless steel construction ensures durability and resistance to corrosion crucial for demanding environments. This liquid-filled gauge features a 2.5-inch dial and a bottom 1/4 NPT brass connection providing clear readings and reliable performance. With an accuracy of 3-2-3% of span this gauge is designed to measure pressures ranging from 0 to 600 PSI or 0 to 40 Bar. The polycarbonate window offers additional protection while the liquid filling helps to dampen vibrations and pulsations enhancing the readability and lifespan of the device. ENGINEERED Speciality Products designed this gauge to maintain optimal performance within a pressure range of 25% to 75% of its maximum scale. The dimensions are A: 2.48 B: 1.21 C: 2.71 D: 0.46 making it compact yet highly efficient for its intended applications. MPN: 63 1008AL 02L 600#-9824 Supplier Part Number: PRO-201L-254K

Question by: Carl E on Feb 3, 2026, 6:05 AM
Running this on a hydraulic press that throws a fair amount of vibration. liquid filled help with that, or am I gonna be replacing it regular?
Answer by: Customer Support on Feb 4, 2026, 1:24 PM
Liquid filling is exactly what handles that kind of environment. The glycerin or oil inside dampens the needle movement caused by vibration and pressure pulsations, which keeps the internal mechanism from wearing out as fast as a dry gauge would. You'll get cleaner readings and a longer service life running it on equipment that cycles hard. One thing worth keeping in mind: if your system regularly runs near that 600 PSI ceiling, pull it back. Normal operation works best between 25% and 75% of the full scale, so keeping your working pressure somewhere in the 150 to 450 PSI range will do the most to extend its life.

got a spot for a bottom-mount gauge with 1/4 NPT threads. is this one a match, and what’s the dial size?
Answer by: Customer Support on Aug 18, 2025, 4:46 PM
It uses a 1/4 NPT bottom connection with a male brass connector. The face is a 2.5 inch dial.

Reckon this gauge would hold up okay outside, or is it more for indoor use?
Answer by: Customer Support on Sep 4, 2025, 6:46 AM
The 304 stainless steel construction is designed to offer good durability and corrosion resistance, which should help it hold up reasonably well in many outdoor environments. Just keep in mind the normal operating pressure recommendation of 25%-75% of the scale.
