Kammprofile gaskets

At the highest pressures and temperatures, kammprofile gaskets are ideal for sealing flange connections under extreme operating conditions. They combine the good adaptability of soft material gaskets with the high stability of metal gaskets.

Type HST-KMP-MA is for use with flange connections with tongue and groove and male and female faces. Type HST-KMP-ZR with integrated centering ring should be selected for use with smooth flanges and flanges with raised face. With gaseous media, or where there are large differences in temperature between internal and external diameters, type HST-KMP-LZR with loose sheet metal centring ring should be used.

The convex kammprofile gaskets exhibit improved sealing properties compared to standard grooved profiles. The improvement is achieved by the decreasing depth of the groove troughs towards the midpoint of the profile.

With gaseous media or large differences in temperature between the internal and external diameters, type HST-KMP-LZR-B with loose sheet metal central edge should be used.
