groovedgraphiteprofile

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. The integral centering ring [machined] is additionally provided with a pre-determined breaking point, 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.
