Metallic gaskets are available in many forms including:
- Solid metal gaskets that require very smooth, plain surface finishes and high clamping forces in order to seal.
- Combinations with soft fillers such as double-jacketed and spiral-wound that can tolerate greater surface roughness and will seat with lesser compressive forces.
- Light cross-section gaskets that are self-sealing and require minimum clamping forces for effective sealing.
In all cases, however, careful attention must be given to
machining details of the flanges and sizing of the gaskets.
