The grooved stainless steel core [1.4571, pitch 1,0 mm] is covered on
both sides with soft material layers made from expanded pure graphite and provided with a loose centering ring [non-integral, half-shells, spot-welded], which prevents vibration breaks in the sealing area.
Grooved gaskets require low minimum sealing surface pressure, but can
also resist very high loads.
Grooved gaskets impress by a high
pressure application limit, low leakage rate and are therefore suitable
for extreme operation conditions. To ensure safety in oxygen applications, we also offer an adhesive-free LE-Safe version of this gasket.
