LeaderKAM Kammprofile Gasket Style KB9

Description

LeaderKAM Kammprofile gaskets consist of a metallic core with machined concentric grooves. Both faces are produced with soft sealing layers consisting of either graphite, PTFE or LeaderTHERM NXT 1010 (high temp. modified Phlogopite). However also metallic (non-ferro) layers of pure silver or aluminium can be produced.
