Grooved gasket [convex-shaped profile] with integral centering ring, pre-determined breaking point and both-sided graphite layers

The convex-shaped 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.
