Durlon® K40-ETG Kammprofile
Durlon® Kammprofile gaskets have a solid metal core with concentrically serrated grooves machined into the top and bottom faces. The metal core is typically stainless steel, but it can be supplied in various metallurgies as per the customer’s request. The serrated core is covered with soft sealing material and is dependent on the service conditions of the system.
Flexible graphite and expanded PTFE sealing layers are most common, but other soft materials can be used as well. While providing the Durlon® Kammprofile gasket with excellent sealing properties, the soft sealing layers also fill in minor flange imperfections and protect the flange surfaces from damage.

Available systems: Durlon® Kammprofile gaskets are offered in 4 styles in each of the 2 core designs.
A loose fitting centering ring is recommended on applications where thermal or pressure cycling can affect the integrity of the serrated metal core. It allows for expansion and contraction of the core through these cycling conditions.CORE MATERIALS | FACING MATERIALS |

AVAILABLE CORE STYLES:
K40PEF & K40CEF - EXTENDED CORE FLOATING, CENTERING RINGSimilar to the floating centering ring, this style has an extended core whereby providing additional strength and stability to the overall floating design. |

K40PI & K40CI - INTEGRAL CENTERING RINGThe centering ring is used to position the gasket between flat face and raised face type flanges. |

K40P - PARALLEL ROOT COREThis core design is where the main sealing faces of the serrated metal core are parallel to each other. These are the standard design of Kammprofile gaskets. |

K40C - CONVEX ROOT COREThis core design is where the main sealing faces of the serrated metal core are slightly convex in profile. The convex core helps compensate when flange rotation is experienced on the bolt |
