Four Layer Construction Head Gasket - MLS-R

 Not all performance head gaskets are created equal. All Permaseal MLS-R head gaskets incorporate state of the art four layer design

  •Active Layers — the top and bottom outer or active layers are manufactured from NOK’s NBR pre-coated stainless steel ensuring excellent micro sealing of engine fluids with precision embossing around critical sealing points to provide additional fluid sealing performance. The use of pre-coated materials ensures greater control of the coating thickness for optimum pressure distribution over the entire gasket.

•Control Layer — the centre or control layer is manufactured from steel and ensures the head gaskets overall thickness tolerances are met.

•Stopper Layer* — manufactured from stainless steel and measuring only 0.15mm thick the stopper layer features a precision fold around the cylinder bores creating a load point around the combustion chamber. Combined with additional embossing on the active layers the stopper layer delivers truly superior sealing of combustion gases.

*Excludes S2096MLSR which has coined edge due to engine design.

Here is a list of the current applications, with more to be added soon.
