KAM Profile Gaskets are high-performance sealing solutions designed for critical flange connections in industries
requiring reliable sealing under extreme pressure, temperature, and corrosive conditions. These gaskets feature
a serrated metal core with a soft facing material, combining the strength of metal with the conformability of
non-metallic layers.
Key Benefits of Kam Profile Gaskets
High sealing performance (low leakage rates) Excellent thermal & mechanical stability Reusable (in some applications) Resistant to blowout under pressure cycling

Storage:
● Temperature: <40°C (to prevent degradation of facing materials)
● Humidity: <60% RH (prevents moisture absorption in graphite)
● Stacking: Store flat to avoid deformation
Installation:
● Flange Preparation: Clean surfaces, remove old gasket residue.
● Alignment: Ensure proper centering (no overhang).
● Bolt Tightening:
● Follow ASME PCC-1 torque sequence (star pattern).
● Re-torque after 24hrs of operation.
Safety:
● PPE: Gloves (for handling graphite/PTFE), safety glasses.
● Ventilation: Required when machining PTFE.
| Issue | Root Cause | Solution |
|---|---|---|
| Leakage | Incorrect facing material | Upgrade to PTFE/graphite |
| Gasket blowout | Over-compression | Use thicker gasket |
| Chemical attack | Incompatible media | Switch to PTFE-lined |
| Bolt relaxation | Thermal cycling | Re-torque after 24hrs |
