Camprofie gaskets (kammprofiel) consist of a metal core with concentric grooves on both sides, topped by sealing materials pressed firmly into the grooves.

The sealing material is thus optimally confined and concentrated in the valleys of the profile, leaving only a thin layer between its tips and the surface of the flange, where a series of concentric seals is created.

This construction improves sealing performance by inducing stress concentrations on the sealing surfaces, while the metal core provides rigidity and resistance to lateral expansion (blow-out).
