LeaderKAM Kammprofile Gasket Style KV

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.
