Grooved gasket without centering ring and PTFE envelope

The grooved stainless steel core [1.4571, pitch 1,0 mm] is provided with a PTFE envelope, which is closed on the inner diameter instead of the commonly glued soft sealing layers.Especially in GMP applications [e.g. food and pharma industry] avoiding the use of adhesives is an advantage in order to guarantee absolute product purity. In addition, the metallic core is not affected by the contact with the media and is protected by the PTFE envelope.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.
