Flat Gaskets
Flat gaskets can be cut by rule die, kiss cut or more complex shapes by water jet cutting. Compression stops or collars can also be incorporated, this leads to reduced hardware costs and negates the need for fixings to be torqued to prevent over compression and damage to the gasket. Self adhesive backing can be applied to the materials prior to cutting.
