AFANTI 2.5MPa Air Compressor System Pressure Gauge | 0-25 Bar / 0-360 PSI | Black Steel Case | M20 Brass Thread |

When your air compressor system runs above 1.6 MPa, you need a gauge that's rated for the job. This 2.5 MPa model gives you the headroom and the resolution — 0.1 MPa fine graduations let you spot pressure drift before it affects your process. The thick matte black case and oversized brass M20 thread connection are built for installations where vibration, humidity, and heavy use are part of daily life.

Protection	IP54 (dust and splash resistant) Features Fine 0.1 MPa graduations — long tick marks every 0.5 MPa with 5 subdivisions between them. Read pressure changes down to 0.1 MPa without guessing. Ideal for systems where small pressure shifts matter. Thick black steel case — heavier-gauge housing than standard models. Extra wall thickness absorbs vibration from compressor pumps and protects the internal Bourdon tube mechanism. M20×1.5 brass thread — the industry-standard metric thread for high-pressure connections. Deeper thread engagement than M14 or M10, providing a more secure seal under sustained pressure. Single MPa scale, zero confusion — one scale, one unit. No converting between PSI and bar in your head. The dial reads exactly what your system specifications call for. Gold-tone center pivot — clearly visible axis point makes it easy to verify pointer position at a glance, even from a distance. Tempered glass lens — resists shop debris, oil spray, and solvent splashes. Won't scratch like plastic or cloud over time. Typical Applications High-pressure air compressor receiver tanks (above 1.0 MPa) Compressed air distribution manifolds and headers Industrial pneumatic system regulator stations Hydraulic-pneumatic hybrid systems Factory main air supply lines Pressure safety monitoring points Installation Notes Use a copper or aluminum sealing gasket with the M20 thread for best leak prevention. Thread seal tape also works — wrap 3–4 turns, keeping tape back from the first thread to avoid debris entering the system. Tighten using a wrench on the hex nut only — gripping the case will damage the internal movement. For pump outlet installations, a snubber or needle valve between the gauge and pump will absorb pulsation and extend gauge life significantly. Ideal working pressure range: 0.8–1.9 MPa (1/3 to 3/4 of full scale). Recalibrate every 12 months for safety-critical applications.
