looking for a gauge that wont rust out. what material is the case and whats the max pressure it reads
Question by: Curt E on Nov 17, 2025, 2:36 PM
The casing is constructed from 304 stainless steel, offering robust protection against rust. It can measure up to a maximum pressure of 300 PSI or 20 Bar, and the liquid filling helps dissipate vibrations to protect the interior parts.

Can this gauge handle hydraulic oil or just water-based fluids?
Question by: Bonnie E on Oct 14, 2025, 12:02 PM
Gauges filled with liquid, like this one, are suitable for hydraulic oil. The case and inner workings are made from 304 stainless steel, making them durable against petroleum-based fluids, which is perfect for typical hydraulic tasks.

what's the fill liquid inside for
Question by: Neal R on Jul 23, 2025, 8:50 PM
The fill liquid reduces needle fluctuations when there's vibration or sudden pressure changes. This makes the reading much clearer, preventing the needle from erratically bouncing.

Got a setup that runs up to 250 PSI, bottom connection needed. This one gonna hold up for that?
Question by: Peggy H on Aug 28, 2025, 12:54 PM
With a capacity of 0 to 300 PSI or 0 to 20 Bar, it works fine for your needs. The liquid fill stabilizes the needle, and it comes with a 1/4 NPT bottom connection, common for many hydraulic setups.
