Grooved gasket without centering ring and both-sided PTFE layers

The grooved stainless steel core [1.4571, pitch 1,0 mm] is covered on both sides with soft material layers made from PTFE [unsintered]. 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.

Grooved gaskets can be manufactured in small thicknesses so that they can be used also in tongue and groove connections in the range of common groove depths.
