LeaderKAM Kammprofile Gasket Style KV9L
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 (modified Phlogopite). however also metallic (non-ferro) layers of pure silver or aluminium can be produced.

good for low to high gasket stresses
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. Nova-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.
Temperature
LeaderKAM Kammprofile Gaskets are suited for temperature range from –250 °C up to 450 degrees °C (steam 550 °C) with graphite layers. LeaderTHERM (phlogopite) layers can withstand temperatures of 900 °C
