Pressure Gauge Internal Parts – Precision Brass & Copper Components

Essential Spare Parts for Accurate Pressure Measurement

Internal spare parts used in pressure gauges—Bourdon tube, movement gears, pointer, links, and socket components—manufactured in brass/copper/steel for precise motion transfer and reliable readings.

These pressure gauge internal parts are essential spare components used in the assembly and servicing of mechanical pressure gauges. Manufactured using high-quality brass, copper, and steel, they work together to convert pressure into mechanical motion and display it accurately on the dial. The Bourdon tube (copper) responds to incoming pressure by flexing/straightening slightly; the movement mechanism (brass gears) amplifies this motion through the connecting link and sector gear, and the pointer (needle) indicates the pressure value. The socket (threaded connection) forms the inlet base and pressure entry point. Ideal for gauge manufacturers, repair professionals, and instrumentation applications requiring reliable internal components.
