Kammprofile gaskets

Kammprofile gaskets, which are also commonly known as serrated metal gaskets or grooved gaskets, are used for high-pressure and high-temperature sealing applications. They typically consist of a one-piece metallic core with concentric serrations or grooves on both sealing faces, often covered with a soft sealing material such as graphite or PTFE (polytetrafluoroethylene).  

These gaskets are specifically engineered to provide reliable sealing performance under pressure conditions, whereas conventional gaskets are liable to distortion or displacement failure. 

Kammprofile gaskets are manufactured in different materials and noncircular shapes with accuracy. They can also be custom-engineered to fit various applications.

Product Details

Style RK1 

RK1 is manufactured without a guide ring for tongue and groove, or recessed flange applications such as male and female. It is typically used in heat exchanger applications and applied as an upgrade to double jacketed gaskets. It is highly suggested to have the nubbin (if present) machined out as a good practice.  Where pass partitions are required, they are also kammprofiled and laminated. They are the same thickness as the ring, and securely held in place with welds. 

Style RK2 

RK2 is constructed with an integral guide ring for aligning purposes. It is suggested to be used in raised face flanges. The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards. 


Style RK3 

RK3 utilizes a loose fit guide ring. This popular design is preferred for nominal pipe size and pressure class raised face flanges and is used in equipment with excessive radial shear characteristics, thermal cycling, and expansions.  The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards.
