Precision Zero Stop Pin for Accurate Readings

Pressure Gauge Dial Stopper Pin

Micro precision pin component used in pressure gauges to stop the pointer at zero and protect internal mechanism for accurate readings.

The Pressure Gauge Dial Stopper Pin, also known as a Zero Stop Pin, is a small yet essential component used in pressure gauges to ensure accurate and reliable readings. Installed on the gauge dial plate, it acts as a stop point for the pointer (needle) and helps protect internal gears during sudden pressure drops. Manufactured using high-precision micro-turning processes, it ensures consistent quality and exact dimensions for dependable gauge performance.
