Ring Plug Gauges
Available Sizes: 203mm, 304.10mm, 354mm, 400mm bore
Product Description
Ring Plug Gauges are used for checking large bore sizes, available for 203mm, 304.10mm, 354mm, and 400mm bores. As the name suggests, these are plug-style gauges built specifically for larger bore diameters, where standard gauge sizes do not apply.
They are supplied in GO and NO GO configurations, allowing a bore to be checked against both the upper and lower acceptable limits in a single verification step.
Because these gauges are used for larger bores, hardness is adjusted for size and ranges from 25-50 HRC depending on the gauge diameter, with larger gauges generally carrying a lower hardness value.
Since accuracy is the primary requirement for a gauge of this kind, manufacturing them involves closer control at every stage, which is reflected in a comparatively higher cost.
These gauges are also produced in low quantities, as demand for large-bore verification tools is inherently limited compared to standard-size gauges.
