<h2>Overview</h2>
<p>The <strong>Festo 162839</strong> pressure gauge is a Bourdon tube analog instrument designed for industrial pneumatic and hydraulic system monitoring. With a measurement range of 0–16 bar (0–225 psi) and a 50 mm diameter dial, this gauge provides reliable, at-a-glance pressure readouts. The model features a centered G1/4 back connection and is rated for operating temperatures from –20 to +60°C (–4 to +140°F), making it suitable for factory floors, machine shops, and field service applications.</p>
