Gauge

This precision assembly requires a pointer-indicator to be held to +/- 3 degrees, the concentricity in a molded polycarbonate lens to be held to +/- .002″, and a hermetic seal of the assembly through sonic welding.

Balance Chamber

The valve stroke on a precision assembly is held to +/- .001”. An internal component has flatness held to .002” across surfaces with diameters 1.050” and .720”. An automatic unscrewing core forms extremely fine 40 threads per inch on a 1.216”I.D. in the outer component.
