Grooved gasket with loose centering ring [non-integral] and both-sided PTFE layers

  • Article Number: 6713KD30
  • Material: 6713
  • Profile: KD30
The grooved stainless steel core [1.4571, pitch 1,0 mm] is covered on both sides with soft material layers made from PTFE [unsintered] 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.
