Standard ‘RIR’ gaskets are manufactured to 0.125" (3.2mm) thickness.
The gasket features a solid metal inner ring nominally 0.090" (2.3mm) thick,
as an integrated part of its design. The inner ring provides a positive stop
preventing the gasket from over compression and possible damage.
Special styles are available in other thickness.
