LeaderKAM Kammprofile Gasket Style KB9


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.

Chemical Compatiblity

LeaderKAM Kammprofile Gaskets are suited for a wide variety of media, e.g. a pH range varying from 0-14. Temperature range from –250 °C up to 450 degrees °C (steam 550 °C) with graphite layers. Leadertherm Mica layers can withstand temperatures of 900 °C. Application/ compatibility guide is available on request.

Delivery Options

All dimensions in a wide variety of materials are possible. Non-standard equipment gaskets can be manufactured up to a diameter of 6000 mm. EN10.204 3.1 certificates can be delivered on request, as well as NACE MR0175/ISO 15156 conformity statement.
