Why it is specified
Cut, stocked and labelled against the flange tables in this catalogue. A gasket is cheap until it is the reason a plant is down, so the material is chosen against the medium and the temperature, not against the drawer it came from.
Typical applications
- Flange joints on process lines
- Heat exchanger end covers
- Pump and valve covers
- Valve stem sealing
Options and executions
- Certificates for the material batch
- Cut to a drawing you supply
- Kits per flange table, boxed
