Import Black Steel High Quality Dry Gauge — Buy in wholesale FOB from Supplier in China

Ma Anshan Exact Instrument Co., Ltd manufactures a dry-type pressure gauge with black steel case and ring construction, designed for hydraulic and pneumatic systems, compressors, and compressed air installations. The gauge employs a brass Bourdon tube movement and brass socket with connection port, rated to accuracy class 1.6% of full scale. Available ranges span vacuum through compound to 6000 psi, with bottom mounting as the configured entry style. The acrylic window provides instrument visibility while the aluminium pointer and dial complete the indicating assembly.

The black steel case and ring offer mechanical protection and a neutral finish for industrial environments where stainless steel is unnecessary. Brass wetted parts suit fluid media that do not clog connection ports or react with copper alloys, making this configuration common in general industrial pneumatic and hydraulic monitoring. The 1.6% accuracy class aligns with EN 837-1 / ASME B40.1 Grade B specifications typical for commercial and light industrial applications. Dry gauges omit liquid filling, so they are lighter and avoid leakage concerns, though they may exhibit pointer flutter in high-vibration locations where glycerin-filled alternatives are standard.

Typical applications include compressor discharge monitoring, machine tool hydraulics, HVAC/R pressure testing, and general plant air systems where operators need local visual indication. Buyers should confirm the exact pressure range, connection thread (typically 1/4 inch or 1/2 inch BSP, NPT, or metric), and whether the application environment requires IP rating, overpressure protection, or vibration damping. The gauge is not specified for corrosive fluids, cryogenic service, or oxygen duty without material upgrade and cleaning verification.
